1. Fuel: the single biggest cost driver
Aviation Turbine Fuel (ATF) makes up 40-50% of an Indian airline's operating cost — far above the global average of around 25%. The reason is taxation: in addition to central excise duty, individual Indian states levy VAT on jet fuel ranging from as low as 1-4% (Uttar Pradesh, Andhra Pradesh) to as high as 20-30% (Maharashtra, Tamil Nadu, Delhi historically). This makes ATF in most Indian metros 35-50% more expensive than at competing Gulf or Southeast Asian hubs.
Airlines pass this through as the YQ fuel surcharge embedded in your fare. When global crude rises or the rupee weakens, ATF rises, and fares follow within weeks.
2. Capacity consolidation reduced competition
| Event | Year | Capacity impact |
|---|---|---|
| Jet Airways grounding | 2019 | Removed ~15% domestic capacity overnight |
| COVID capacity cuts | 2020-21 | Temporary but deep; slow recovery |
| Go First insolvency | 2023 | Removed ~7-8% domestic capacity |
| Vistara–Air India merger | 2024-25 | Consolidated 2 carriers into 1 |
As of 2026, IndiGo (~62%) and the Air India group — Air India + Air India Express + the merged Vistara (~27%) — control roughly 90% of domestic capacity. With fewer competing carriers, there's less downward fare pressure, especially on routes where only 1-2 airlines operate.
3. Airport charges keep rising
Privatised airports (Delhi, Mumbai, Bangalore, Hyderabad and others under the Adani/GMR groups) levy User Development Fee (UDF) and Passenger Service Fee (PSF) that have risen steadily. These are baked into your ticket as taxes. Tier-1 metro departures carry higher airport charges than smaller airports.
4. Rupee depreciation
Aircraft leases, spare parts, maintenance, and fuel are largely dollar-denominated. As the rupee weakens against the dollar, Indian airlines' costs rise even if global prices stay flat — and that flows into fares.
5. Demand outpacing supply on peak routes + seasons
India's air-travel demand has grown faster than airlines could add aircraft (delivery delays + the Pratt & Whitney engine issues that grounded part of IndiGo's A320neo fleet in 2024-25). On high-demand routes and during festival/wedding seasons, dynamic pricing pushes fares 2-4x base levels.
How to find cheaper flights despite high prices
- Book 3-7 weeks ahead. The cheapest fare buckets sell first. See our best time to book guide.
- Fly Tuesday, Wednesday, or Saturday. Consistently cheaper than Monday/Friday/Sunday.
- Choose off-peak times. Early morning (before 7 AM) and late night (after 9 PM) flights are 10-20% cheaper.
- Avoid festival + wedding-season peaks. Diwali, Dec holidays, May-June, Nov-Feb weddings.
- Fly low-cost carriers (IndiGo, Akasa) over full-service when you don't need the frills.
- Set price alerts + compare nearby airports.
- Book on HappyFares — zero convenience fee saves ₹150-499/passenger vs other OTAs on top of the lowest base fare.
Will flight prices come down?
Structurally, prices ease only when: states cut ATF VAT (a few have, to 1-4%), new capacity arrives (Akasa's fleet growth, IndiGo's A321XLR + wide-body orders), global fuel falls, or the rupee strengthens. The Indian government has been pushing states to bring ATF under GST — if that happens, it would be the single biggest structural fare reduction. Until then, smart timing is your best lever.
Frequently asked questions
Why are flights so expensive in India in 2026?
Indian airfares are driven up by five factors: (1) Aviation Turbine Fuel (ATF) is 40-50% of an Indian airline's operating cost — far higher than the global ~25% — because of high state VAT on jet fuel (4-30% by state) on top of central excise. (2) Limited competition after the Jet Airways + Go First exits left IndiGo + Air India group with ~90% share. (3) Airport charges (UDF, PSF) at privatised airports keep rising. (4) Rupee depreciation raises dollar-denominated costs (aircraft leases, parts, fuel). (5) Demand outpacing capacity on peak routes + festival/wedding-season surges.
How much of a flight ticket is fuel cost in India?
ATF (Aviation Turbine Fuel) is roughly 40-50% of an Indian carrier's total operating cost — among the highest in the world. The global average is ~25%. The difference is taxation: many Indian states levy 20-30% VAT on jet fuel on top of central excise, making Indian ATF 35-50% costlier than in Gulf or Southeast Asian hubs.
Why did flight prices increase after Go First and Jet Airways shut down?
Capacity consolidation. Jet Airways (2019) and Go First (2023) exits removed ~15-20% of domestic seat capacity. With fewer seats chasing the same demand, fares rose — basic supply and demand. IndiGo + the Air India group (incl. Vistara merger, AIX) now control roughly 90% of domestic capacity, reducing price competition on many routes.
Are flight prices higher during festivals in India?
Yes, significantly. Diwali, Christmas/New Year, summer holidays (May-June), and the wedding season (Nov-Feb) see fares 2-4x the base level on popular routes. Airlines use dynamic pricing — as seats fill, the fare bucket steps up. Book 4-8 weeks ahead for festival travel to avoid the steepest buckets.
Will flight prices come down in India?
Structurally, only if: (a) states cut VAT on ATF (some like UP, Andhra have cut to 1-4% — fares from those hubs are slightly lower), (b) new entrants like Akasa add capacity, (c) ATF global prices fall, or (d) the rupee strengthens. Short-term, fares track fuel + season + demand. Off-peak (Feb-Mar, Aug-Sep) and Tue/Wed departures are consistently cheaper.
Which Indian airports have cheaper flights due to lower fuel tax?
States that cut VAT on ATF to 1-5% (vs 20-30% elsewhere) make flights from their airports marginally cheaper: Uttar Pradesh (Lucknow, Varanasi), Andhra Pradesh (Visakhapatnam, Vijayawada), and a few others. Airlines also add more flights from low-VAT airports, improving competition + fares there.
How can I find cheaper flights despite high prices in India?
Book 3-7 weeks ahead, fly Tuesday/Wednesday/Saturday (cheaper than Mon/Fri/Sun), use off-peak times (early morning / late night), set price alerts, compare nearby airports, fly low-cost carriers (IndiGo/Akasa) over full-service, and avoid festival/wedding-season peaks. HappyFares charges zero convenience fee so you save ₹150-499 per passenger vs other OTAs on top of finding the lowest base fare.
What is the YQ fuel surcharge on Indian flight tickets?
YQ is the carrier-imposed fuel surcharge — part of the base fare, set by each airline based on fuel cost. On domestic tickets it ranges ₹500-2,500; international ₹3,000-12,000. It's refundable on cancellation (minus the cancellation fee). Use our fuel surcharge calculator at /tools/fuel-surcharge-calculator to estimate it for your route.
