Higher Fuel Costs Force Indian Carriers to Reduce Slots

The festive travel surge that usually accompanies Ganesh Chaturthi, Navratri and Diwali is being met with a contraction in airline seat supply for September 2026. OAG data reveals a year‑on‑year decline of 4.5% in total scheduled seats, falling from 2.38 crore to 2.27 crore. The domestic segment bears the brunt, with seats dropping 5.6% to 1.5 crore, while international capacity fell 2.1% to 77 lakh.

The catalyst behind the capacity cut is the rise in aviation turbine fuel (ATF) prices, which climbed 5.46% to Rs 121.28 per litre on 1 September. Fuel expenses represent a substantial share of airline budgets, and the spike has compelled carriers to withdraw from marginal routes.

Additional pressures stem from airspace limitations linked to the West Asian conflict, forcing airlines onto longer detours. The continued prohibition of Indian aircraft over Pakistani airspace further inflates travel time and fuel burn on several international corridors.

While a reduction in seats does not automatically translate into higher fares, the market dynamic of strong demand versus shrinking supply often results in price pressure. The DGCA reports that average fares on 72 major domestic routes rose roughly 20.5% between March 2025 and June 2026. Seat load factors in July remained high at 83.1%, indicating that airlines are still operating near full capacity.

Carrier‑specific impacts are evident: IndiGo’s September seat inventory fell 4.5% to about 1.12 crore, Air India trimmed 8.8% to 32.2 lakh seats, and Air India Express reduced its offering by 2.6% to 25.4 lakh seats. Air India also highlighted a 15% capacity reduction from June to August caused by aircraft shortages and delayed deliveries.

Among the ten busiest Indian airports, only Delhi and Pune have posted a marginal rise in seat numbers. In Kerala, domestic routes such as Mumbai‑Kochi and Bengaluru‑Kochi have actually increased, whereas flights to Gulf destinations have been curtailed. Travelers planning to fly during the holiday period should book early, as the combination of fewer seats, higher fuel costs and sustained demand is likely to make last‑minute tickets more expensive.
