Could Turkish Airlines Really Ghost Boeing — and Swipe an Airbus Instead?

Turkish Airlines’ chair Ahmet Bolat dropped a line in Stockholm that sounds like the opening move of a very expensive chess game: the carrier’s tentative order for up to 150 Boeing 737 MAX jets is conditional — and if engine talks with CFM International don’t land on acceptable economic terms, the airline could pivot and buy Airbus aircraft instead.

The set-up: a presidential handshake… and an asterisk

The Boeing deal — reported as part of a larger package announced around President Erdogan’s meeting with U.S. President Donald Trump in late September — was widely publicized but always carried an important caveat: the 737 MAX purchase depends on a separate engine agreement with CFM. In short: aircraft are one thing; engines are the other — and both have to agree to dance.

Engines: the awkward, expensive heart of the matter

CFM International (a GE–Safran joint venture) is the sole engine supplier for the 737 MAX. Airbus’ A320neo family, by contrast, can be fitted with engines from Pratt & Whitney or CFM — which gives airlines more bargaining chips. Bolat explicitly reminded the industry that, with Airbus, “I have choices.” Translation: competition = leverage.

Why the fight is so bitter (and why it matters)

Airlines and engine makers historically play a long game: engines are often sold close to cost, and the profits come from decades of maintenance and service contracts. But a recent spike in wear-and-tear, parts shortages and maintenance delays has made hourly- or life-cycle pricing riskier — and airlines understandably want protection from sudden cost blowouts. Turkish Airlines is pushing for long-term repair/maintenance terms that shift less risk onto the carrier; CFM has been cautious about offering that — hence the standoff.

The dominoes: what this could do to the Boeing–Airbus scoreboard

If Turkish Airlines flips its order to Airbus, it’s not just a commercial embarrassment for Boeing — it would be a public demonstration that engine-supplier economics can trump manufacturer brand loyalty. For Airbus, it’s a marketing wet dream: “Want options? Buy Airbus.” For Boeing, it’s a reminder that singular supply chains (i.e., one engine choice) can become bargaining liabilities when relationships sour.

The 777X sidebar: love for Boeing, but not “in a rush”

Bolat also signaled that THY hasn’t given up on larger Boeing types such as the 777X — the airline is monitoring the program and said it would order when the timing is right. The 777X program has slipped repeatedly and is now widely expected to enter service around 2027; Turkish Airlines is cautious but interested. So—no full breakup; maybe a very polite break-up text with Boeing, followed by occasional DMing.

Short-term pain, long-term chess: operational consequences

Turkish Airlines already faces engine-related operational stress: Pratt & Whitney delays have grounded dozens of aircraft and created maintenance backlogs that stretch into months. These service bottlenecks have raised fares, increased spare-part prices and forced airlines — including THY — into tough negotiations over who pays for what when engines need major work. That context makes Bolat’s tough stance easier to read: when your network depends on aircraft being available, you can’t afford open-ended maintenance risks.

Why this story is delicious for the industry — and a bit scary for travelers

• It’s a reminder that airplane shopping isn’t just about paint schemes and seat maps — engines and long-term MRO (maintenance, repair, overhaul) economics can decide fleet strategies.
• It shows how geopolitics and presidential-level optics can announce big deals, while the real work — contract minutiae with component suppliers — happens in quiet conference rooms.
• For passengers: if engine shortages and repair backlogs persist across the industry, that can mean fewer available seats and more flight disruptions. Translation: book that holiday, but maybe don’t plan a connecting tightrope walk.

What happens next (a quick playbook)

• CFM and Turkish Airlines continue negotiating. If CFM softens on hourly/long-term repair terms (or offers a price that balances their risk), Boeing stays in the picture.
• If negotiations stall, THY can credibly shift to Airbus — and leverage Airbus’ dual-supplier engine strategy to extract better deals.
• Industry watchers will watch supply chains (engines and parts), political optics, and which side budges first — the one who blinks may still get a better invoice.

Verdict (with a wink)

This isn’t a rom-com breakup; it’s corporate negotiation theatre where the actors are jetliners, and the props are billions of dollars. Turkish Airlines’ threat to “change to Airbus” is both strategic noise and a genuine card to play: the airline has the scale to make vendors sweat. For Boeing, it’s a reminder that even a presidential backdrop doesn’t close every commercial problem — the fine print does.

TL; DR

• Turkish Airlines may switch a tentative 150-aircraft Boeing 737 MAX order to Airbus if engine talks with CFM fail.
• The Boeing deal was announced around a late-September presidential meeting but depends on a separate engine agreement.
• CFM is the sole 737 MAX engine supplier; Airbus offers multiple engine options — greater bargaining power for airlines.
• Engine supply and maintenance delays (Pratt & Whitney issues among them) have grounded planes and strained airline operations, pushing carriers to demand better long-term repair terms.
• THY still likes Boeing’s 777X but says it will order only “when the time is right”; the 777X remains delayed into around 2027.

SpiceJet just dropped a surprise starter pack for the holiday season — an Airbus A340 wide-body and two Boeing 737s have been added to its operational fleet as the airline kicks off a winter expansion to handle the surge in travel demand. The trio will begin flying between October 10–11, and they’re only the opening act of a much bigger ramp-up.

What landed (and why you should care)

• The hardware: One Airbus A340 (wide-body) and two Boeing 737 narrow-bodies have been inducted into SpiceJet’s operational fleet — the A340 giving the carrier long-haul / high-capacity flexibility while the 737s shore up domestic/trunk routes.
• Timing: Operations for these three aircraft were slated to start between Oct 10–11, timed perfectly to catch the early wave of winter and holiday travel.

Think of it as SpiceJet putting out a bigger table for the festive buffet — more seats, more meals, and fewer people left staring at an empty plate.

The grand plan: damp leases, 20 aircraft, and a comeback script

This is just phase one. The airline said it will induct a total of 20 aircraft under a damp lease model between October and November, then return four previously grounded planes by mid-December, aiming to more than double its operational fleet and triple its ASKM (available seat-kilometers) by December 2025. That’s aggressive growth — and the kind investors love when it comes with a plausible ops plan.

(Damp lease = crew + maintenance support provided by lessor in varying degrees — a fast way to scale without waiting for new aircraft deliveries. Less sexy than fireworks, but far more useful for on-time boarding.)

Markets noticed (and cheered)

SpiceJet stock enjoyed a bump after the announcements — trading in the mid-30s rupees range on the BSE around the news — a sign that Dalal Street is rewarding capacity expansion moves when they come with a credible timeline. That market reaction follows a string of recent fleet and financial moves by the airline.

What this means for flyers

• More seats, more routes: Expect new route announcements and increased frequencies on popular leisure and VFR (visiting friends & relatives) sectors. The A340 could enable longer-haul or higher-density trunk operations.
• Short term bumps: Adding leased aircraft quickly can cause small teething issues — cabin trim, catering flows, slot adjustments — but it’s also the fastest way to reduce waitlists and angry DM threads. (Nobody likes a delay, except true conspiracy-theorists.)
• Fare pressure: More seats during peak demand could slightly dampen fare spikes on some routes — good news if you hate paying premium for holiday travel.

Risks and the fine print

SpiceJet’s expansion is bold, but it’s not risk-free. Rapid fleet growth through leases requires careful crew planning, maintenance arrangements, and cashflow discipline. The airline has recently been active in fixing legacy liabilities and negotiating leases — progress has been visible but the execution will be watched closely by investors and regulators alike.

Also: wet/damp leases and short-term inductions sometimes bring mixed cabin experiences if the interiors differ — so frequent flyers, pack your patience (and maybe a seat cushion).

Why this matters to Indian aviation

India’s domestic market is one of the fastest recovering and growing in the world. If SpiceJet nails this plan, it could meaningfully increase competition on leisure and secondary city routes, push incumbents to add capacity or face yield pressure, and offer more travel options during the festive surge. If it stumbles, the longer-term recovery narrative may slow. Either way: buckle up — it’ll be interesting.

Closing (with a smile)

SpiceJet’s three-aircraft induction reads like the pilot episode of a comeback series: a wide-body leading the plot, two 737s as reliable sidekicks, and a whole season of planes promised down the road. If you love airports, route maps, or the smell of jet fuel at dawn — this is popcorn-worthy aviation theatre.

TL; DR

• SpiceJet inducted one Airbus A340 and two Boeing 737s, starting operations between Oct 10–11.
• This is phase one of a plan to add 20 aircraft via damp leases (Oct–Nov) and return 4 grounded planes by mid-December.
• The airline aims to more than double its operational fleet and triple ASKM by Dec 2025.
• Markets reacted positively; shares traded in the mid-30s rupees range around the announcement.
• Upside: faster capacity, more routes, better holiday seat availability. Downside: execution risks around leases, crew, and maintenance.

The short answer: apparently, yes — and it’s making airlines do a very unsexy thing called “wait.”

Turkish Airlines’ finance chief warned the aviation world this week that painfully long repair times for Pratt & Whitney engines — averaging around 200 days — will leave dozens of its Airbus A320neo-family jets parked well into 2027. The carrier expects to end 2025 with about 45 Airbus jets grounded (up from 35 earlier this year) and says the problem will likely persist “at least” until mid-2027.

What actually happened (the boring-but-important timeline)

• Pratt & Whitney’s geared turbofan (GTF) engines — hugely efficient but currently beset by inspection/repair bottlenecks — have needed replacement parts, special inspections and complex shop work. That backlog has translated into turnaround times that are, astonishingly, measured in months rather than in weeks.
• The result: whole A320/A321neo aircraft powered by those engines sit idle while airlines wait for engines to be fixed and returned to service. Turkish Airlines reports about 200 days on average per engine turnaround for affected units.

Who’s getting burned (spoiler: passengers and airline balance sheets)

This is not just a Turkish-only headache. Carriers across Europe have seen the pain: Wizz Air, for example, has also reported dozens of grounded jets and has predicted the disruption could stretch into 2027 for its fleet planning. The shortage of available aircraft has pushed fares up, squeezed capacity, and sent the price of engine spares skyward — a textbook supply-shock.

Why it isn’t fixed yet (and why optimism is polite, not confident)

Pratt & Whitney (owned by RTX) has been working to ramp repair capacity and innovate (including additive manufacturing for parts), but fixing global shop capacity and specialized tooling — and recovering from strikes and complex inspections — is not a pop-up shop job. RTX executives have said the number of aircraft on the ground has stabilized and that more work remains to bring things down, while MRO workloads are growing fast. Those steps help, but they take calendar time.

The dominoes: how one engine problem ripples into bigger moves

• Airfares: fewer aircraft = fewer seats on popular routes = higher prices for passengers.
• Negotiations: airlines are renegotiating maintenance deals and seeking compensation where they can. Turkish said it received “some reasonable compensation” from Pratt/W.
• Fleet strategy: To cope with shortages, carriers are accelerating leasing plans, mulling cross-make deals, or even hedging with alternate engine/airframe combinations. Turkish’s big conditional deal with Boeing (225 jets, 150 of them 737 MAX) was reported as contingent on securing engines from CFM — a clear nod to the complexity the engine crisis creates.

Turkish Airlines’ playbook: patience, compensation, and Plan B (a.k.a. renting friends’ planes)

Turkish appears to be doing the pragmatic three-step dance: accept limited compensation from the engine maker, shuffle schedules and route plans (reduce flights where necessary), and put in big orders or leases to ensure long-term capacity. The airline’s CFO bluntly signaled that the spare-parts and shop bottlenecks are not a quick fix: “Next year, it will continue in the same fashion.”

If an airplane could sigh, this one would. “I just want to fly again,” it says, as it stares at the hangar lights and scrolls job listings for ‘turbo-fan therapist’.

What passengers should expect (practical, not panic)

• Expect higher fares on heavily affected routes while groundings persist.
• If you have a ticket, check airline rebooking policies; many carriers are offering flexible changes to reduce customer pain.
• If you’re a frequent flyer, keep an eye on schedule changes — your upgrade chances may be a rollercoaster (fewer planes = chaotic upgrades on some days, more opportunities on others).

The industry view — possible fixes (and why they’re not instant)

• Scale up MRO capacity — requires trained workforce, test stands, and supply chains; months to years.
• Additive manufacturing & tech fixes — promising and can cut repair times when validated, but adopting at scale is gradual.
• Strategic engine sourcing — airlines may shift future orders to different engine suppliers or diversify suppliers on new aircraft to lower single-supplier risk. Turkish’s Boeing/CFM caveat is an example.

So… is mid-2027 the new landing strip for this problem?

It’s a reasonable (if undesirable) working estimate. Multiple airlines and executives are now flagging 2027 as the horizon when the worst of the backlog could subside — assuming repair ramps go to plan and there aren’t fresh surprises. But aviation loves a plot twist, so yes: mid-2027 is the target, not a guarantee.

Final thought (serious): resilience now, prudence later

This episode is a case study in how a single complex component — albeit an extremely complicated and wonderful piece of engineering — can create system-wide fragility. Airlines will likely reconsider diversification of suppliers, and OEMs will keep investing in MRO capacity and innovations like additive repair. For travelers, the impact is tangible now; for the industry, the lesson should be durable: build redundancy before the next bottleneck appears.

TL; DR

• Turkish Airlines expects the Pratt & Whitney engine repair backlog to last at least until mid-2027, leaving dozens of A320-family jets grounded.
• Around 45 Airbus jets are expected grounded by end-2025 (up from 35 earlier).
• Average engine turnaround times have ballooned to ~200 days, choking capacity and boosting fares and spare-part prices.
• RTX/Pratt & Whitney says cases have stabilized and MRO workload is rising; the company is investing in fixes (including additive manufacturing) — but scale-up takes time.
• Airlines are seeking compensation, rearranging fleets, and hedging future orders (Turkish’s Boeing deal is conditional on engine supply) to reduce future single-supplier risk.

With Inputs from Reuters

Airbus just pulled off a classic underdog-to-top-dog move — except this time the underdog had runways in Toulouse, Hamburg, Mobile and Tianjin. On Tuesday the A320 family officially overtook the Boeing 737 to become the most-delivered jetliner in commercial aviation history after Airbus handed an A320neo to Saudi low-cost carrier Flynas, bringing cumulative A320 family deliveries to 12,260 since the model entered service in 1988. That milestone — verified by aviation analytics firm Cirium — ends a decades-long delivery lead once held by the 737.

Why this matters (beyond vanity plates and bragging rights)

The A320’s leap to No.1 isn’t just a number on a scoreboard. It highlights several industry trends that reshaped global air travel:

• Design + timing = endurance. Launched in the mid-1980s, the A320 introduced fly-by-wire to the single-aisle market — a bold avionics leap that set a new standard for future airliners and made the family adaptable and attractive to many operators.
• Low-cost carriers rewrote the script. Originally built for hub carriers, the A320 family later became the backbone of low-cost fleets worldwide — a strategic pivot that proved hugely lucrative.
• Massive scale of narrow-body travel. Together, Airbus and Boeing have delivered more than 25,000 narrow-body jets (A320 family + 737 family), underlining how single-aisle aircraft continue to drive global connectivity.

How Airbus climbed the mountain (a short playbook)

• Family philosophy. Airbus designed the A320 as a “family” — A318 to A321 — with cockpit commonality, simplifying crew cross-qualification and airline training costs. Pilots could jump between variants without missing their coffee break.
• Neo payoff. The A320neo (new engine option) program gave airlines a fuel-burn and emissions edge, locking in orders and keeping the product line competitive well into the 21st century. (Yes, “neo” is aviation shorthand for “make your accountants smile.”)
• Global assembly footprint. With final assembly in Europe, the U.S. (Mobile), and China (Tianjin), Airbus distributed production risk and won local customers and political goodwill — handy in a multi-national business.

Boeing’s side of the story: turbulence and a recovery taxi

Boeing’s 737 family was once the unchallenged ruler of narrow-bodies; the company responded to Airbus’s threat over the years (737 Next Gen, 737 MAX). But a series of high-profile crises — especially the 737 MAX accidents and subsequent fallout — dented Boeing’s momentum and reputation. The company has been working on stabilizing operations and culture under CEO Kelly Ortberg, and while deliveries and production are improving, catching up on cumulative historical deliveries is a tall order.

Not a knockout — more like a long, polite boxing match

This is not a moral victory where one company vanishes and the other dances on the fuselage. It’s a shifting of a marathon lead — Airbus now leads in cumulative narrow-body deliveries, but Boeing still holds the proud lineage of the 737 and remains a global aerospace heavyweight. Both companies have powerful backlogs, and both are carefully weighing whether — and when — to develop next-generation narrowbodies (engine tech and economics will be the referees).

The futurist footnote: who’s next at the gate?

New challengers are circling: China’s COMAC, evolving Brazilian strategies at Embraer, and nimble startups proposing radical designs. Still, for now, the duopoly’s cash cows — Boeing’s 737 variants and Airbus’s A320 family — are delivering profits and keeping airlines happy. Neither giant is in a rush to replace a cash-generating product without a leap in engine or design tech that justifies the cost.

A few delightful data crumbs (because numbers are plane-tastic)

• A320 family deliveries reached 12,260 with Flynas’s A320neo handover — the specific milestone tracked by Cirium and widely reported. 
• Airbus reported strong delivery momentum and a global production footprint; their official orders & deliveries dashboard shows the scale of the company’s operations heading into 2025.

So — champagne for Toulouse or cake for Seattle?

Both, obviously. Airbus has earned a major commercial milestone; Boeing has earned the right to retool, reorganize, and maybe come back swinging when the next big technological sea change arrives. The airline passenger wins either way — more efficient jets mean smaller bills for carriers and (eventually) fewer emissions per passenger. Also, more in-flight Wi-Fi. Priorities.

TL; DR

• Airbus’s A320 family became the most-delivered jetliner ever after an A320neo delivery to Flynas raised the total to 12,260.
• The A320’s legacy rests on fly-by-wire innovation, a family-type approach, and strong adoption by low-cost carriers.
• Airbus and Boeing together have delivered 25,000+ narrow-body jets, reflecting the single-aisle market’s dominance in global travel.
• Boeing has faced safety and production crises in recent years (737 MAX era), but is stabilizing under CEO Kelly Ortberg and remains a major competitor.
• Neither Airbus nor Boeing is rushing to replace their cash-cows — they’re waiting for engine and tech advances before betting the farm on a new narrow-body design.

With Inputs from Reuters

As the Festival of Lights approaches, India's aviation sector prepares for one of its busiest periods. With Diwali scheduled for October 20, 2025, millions of travellers are planning journeys home to celebrate with loved ones. This festive migration has prompted India's civil aviation authorities to take decisive action, ensuring that surging demand doesn't translate into unaffordable ticket prices. The response involves a massive expansion of flight operations and stringent regulatory oversight to protect passenger interests during this crucial travel season.

Diwali Fare Increases

The Directorate General of Civil Aviation (DGCA) has stepped in to address concerns about skyrocketing airfares during the festive period. The aviation regulator has committed to maintaining rigorous oversight of fares and capacities throughout the festival season. This proactive approach comes as domestic routes historically experience significant price spikes when travel demand peaks. Although India operates under a deregulated airfare system, the DGCA retains the authority to monitor pricing trends and intervene when necessary to prevent excessive increases that could burden travellers.

Massive Flight Expansion

In response to regulatory directives, India's leading airlines have announced substantial capacity additions. IndiGo, the country's largest carrier, plans to deploy approximately 730 additional flights covering 42 routes. Air India and its subsidiary Air India Express will jointly introduce 486 extra services across 20 sectors. Meanwhile, SpiceJet is contributing 546 supplementary flights spanning 38 routes. This collective expansion totals over 1,700 additional flights, representing a significant boost to domestic aviation capacity.

SpiceJet has also launched special daily non-stop connections to Ayodhya from Delhi, Bengaluru, Ahmedabad, and Hyderabad starting October 8, 2025, catering to the spiritual tourism surge during the festive season.

Price Concerns

Recent reports indicate that domestic flight tickets from Delhi and Mumbai to major northern cities have surged to 30,000, while international flights to destinations like Thailand, Malaysia, and Singapore remain available for approximately 17,000. This pricing disparity has generated considerable frustration among domestic travellers, highlighting the challenges of balancing demand with affordability.

Bottom Line

The Indian aviation industry is gearing up for the Diwali travel rush through coordinated efforts between regulatory bodies and major airlines. With over 1,700 additional flights planned across key routes, carriers are attempting to accommodate the festive surge while regulators maintain vigilant oversight of pricing practices. 

Despite these capacity enhancements, concerns about elevated domestic airfare persist, with some routes commanding prices higher than international destinations. The success of these measures will ultimately be determined by whether travellers can access affordable options during this peak travel period, as the aviation sector balances commercial viability with consumer protection.

Yes, apparently, it’s complicated — and the Supreme Court just agreed to peek under the hood. Strap in: this one’s about legal labels (is it a good or a service?), tax drafting that looked like a fix but smelled like an expansion, and an airlines-versus-taxman drama that keeps looping through the courts.

The short version (aka “what just happened?”)

On 6 October 2025 the Supreme Court issued notice to InterGlobe Aviation (IndiGo’s parent) after hearing an appeal by the customs department about whether IGST should be levied when goods (aircraft engines/parts) are re-imported after being sent abroad for repairs. The bench (Justices B.V. Nagarathna and R. Mahadevan) sought IndiGo’s response and the matter is listed for further hearing (the Economic Times reports the next hearing is on 21 November 2025).

Why this tax fight matters — in plain English (and with some aviation coffee)

When airlines send expensive parts overseas for maintenance, there are two relevant things that happen:

• They pay the overseas repair bill (a service).
• The fixed parts are then re-imported into India.

The government’s position (as reflected in a 2021 notification and later CBIC clarifications) was that IGST could be levied on such re-imports — effectively taxing the transaction again when the repaired item returned. Airlines like IndiGo argued this is double taxation: the transaction is an import of services (repair service) not a fresh import of goods that should attract IGST under customs rules.

The legal timeline (fast but accurate)

• Pre-GST (1996 rule): Re-imports after repairs were taxed only on repair cost, insurance and freight — no double taxation.
• July 2017 (GST rollout): Notifications carried forward the idea that IGST/cess should apply only on repair cost, insurance and freight (not the full value).
• 19 July 2021 (CBIC circular): CBIC issued a clarification reiterating IGST applies to repair/insurance/freight only — but subsequent notifications and wording caused confusion.
• March 2025 (Delhi High Court): The Delhi HC struck down a portion of a 2021 customs notification that effectively expanded IGST/cess on re-imports, calling that expansion unconstitutional — a big relief to airlines. The HC said IGST on imported services can only be imposed under Section 5(1) of the IGST Act, not by a customs notification.
• 14 July 2025 (Supreme Court earlier ruling): In an earlier episode the Supreme Court dismissed a CBIC plea seeking retrospective IGST on re-imports — the bench said retrospective tinkering cannot be used to impose new tax liabilities. That was applauded by industry as legal certainty.
• 6 Oct 2025 (latest): The customs department is back before the Supreme Court and the court has issued notice to IndiGo — the hearings continue (next listed for 21 Nov 2025 per reporting). So — yes — the story isn’t fully over.

The arguments (short and spicy)

Customs / CBIC: Says Section 3(7) of the Customs Tariff Act allows an additional duty; the 2021 wording was an attempt to clarify and capture IGST in the customs scheme — and, crucially for revenue, they say they must protect tax collections. They argue the HC shouldn’t have declared those provisions unconstitutional.

IndiGo (and industry): Says those parts remained its property and the overseas activity was a service (repair) that was already taxed as import of services — you can’t tax the same supply twice by recharacterizing it as import of goods on return. IndiGo also says refunds ordered by the HC are getting stuck.

Stakes: Who wins and who pays (and who might cry over spreadsheets)

• Airlines: If the HC view ultimately prevails, carriers avoid potentially large IGST bills and get refunds/relief — meaningful savings for a capital-intensive sector that ships parts for global maintenance.
• Government: If customs win, it could unlock revenue (and precedent to tax similar re-imports) — but at the cost of legal battles and industry pushback.
• Passengers: Indirect impact — higher costs for airlines can eventually ripple into fares or maintenance budgets; relief helps keep operational costs sane. (Economics 101: maintenance is not free.)

Two likely outcomes (and one wildcard)

• Court confirms HC view — IGST cannot be imposed via customs notification where the underlying activity is an import of services. That restores the pre-existing legal certainty and helps airlines recover refunds.
• Court sides with customs (narrowly) — Government gets more leeway to treat certain re-imports as taxable under customs law; expect appeals, policy fixes or a legislative patch.
• Wildcard: The Court may craft a middle path: clarify drafting, limit retrospective effect, and ask CBIC to tighten its rules — which would be a practical, less dramatic fix.

Why lawyers are loving this (and journalists are living on the quotes)

This row tests basic tax grammar: how do statutes interact — IGST Act vs Customs Tariff Act vs administrative notifications? When courts parse language like “tax and cess” or the meaning of “import”, the result cascades through billions in trade. There’s also a constitutional angle — can an administrative notification effectively change the scope of a law? The Delhi HC thought not. The customs department thinks otherwise. The Supreme Court will (again) have the final say.

A quick, slightly cheeky takeaway

Think of a spare aircraft engine as a very expensive pair of shoes: you send them for a shine (pay someone overseas), then bring them back. The question here is whether the government can bill you again at customs as if you bought a new pair — or whether you only ever paid for the shine. The High Court said “you paid for the shine — stop billing us like we bought sneakers.” The customs department has asked the Supreme Court to re-look. Court drama continues.

What to watch next

• 21 Nov 2025 — the date reported for the next Supreme Court hearing. Keep an eye on whether the bench narrows the issue (refunds/compliance) or reopens the constitutional question.

TL; DR

• The Supreme Court issued notice to InterGlobe (IndiGo) on 6 Oct 2025 in a dispute over IGST on parts re-imported after overseas repair.
• The Delhi High Court (March 2025) struck down part of a 2021 customs notification that expanded IGST on such re-imports, saying those are taxable only as imported services under the IGST Act.
• In July 2025 the Supreme Court earlier gave airlines relief by dismissing a CBIC plea seeking retrospective IGST; nevertheless customs has pressed matters again and the SC has taken up the current appeal.
• Key tension: double taxation risk vs. the government’s view of customs’ power to levy additional duties via notifications.
• Next big legal date reported: 21 Nov 2025. Watch for refund payments getting unstuck or a fresh declaration from the apex court.
