NEW DELHI: Indian carriers flew 864.04 lakh domestic passengers in the first half of 2026, up 1.44 per cent. Seats at Delhi alone rose 6.5 per cent year on year in July. Put those two rates side by side and the sector’s central commercial question comes into focus.
Traffic growth of 1.44 per cent over six months is modest by the standards Indian aviation has taught the market to expect. Capacity, meanwhile, continues to arrive: Delhi offered about 2.60 million seats in July, up 6.5 per cent on the same month last year, with Mumbai at 1.60 million and Bengaluru at 1.56 million. When seats grow several times faster than passengers, the adjustment happens in one of two places — load factors fall, or fares do — and usually in both. That is excellent news for a traveller and a demanding environment for an airline’s revenue management desk, which must fill aircraft without letting yields slide below the level at which the route pays for itself.
The gap that sets fares: seats at Delhi up 6.5 per cent in July against national passenger growth of 1.44 per cent in the half-year. Capacity ahead of demand is a passenger’s market.
Aircraft are ordered five years before they fly. Demand is booked five weeks ahead. The mismatch between those two clocks is most of what airline economics consists of.
At a Glance
• Domestic passengers, H1 2026: 864.04 lakh, up 1.44 per cent year on year
• IndiGo: 555.83 lakh passengers, 64.3 per cent share in the January–June period
• Air India group: 221.67 lakh passengers, 25.7 per cent share
• Concentration: the two groups together account for about 90 per cent of the domestic market
• Capacity, July 2026: Delhi about 2.60 million seats (up 6.5 per cent), Mumbai 1.60 million, Bengaluru 1.56 million
• New capacity: Navi Mumbai International, opened December 2025, ranked tenth by seats in its eighth month
The structural feature underneath all of this is the timing mismatch that defines the industry. Aircraft are ordered years ahead on long delivery schedules, and airport terminals longer still; passengers book weeks ahead and respond to fares almost immediately. Capacity therefore arrives on a schedule set by decisions taken in a different economic climate, and it cannot be withdrawn quickly when it lands into a softer market. Navi Mumbai International is the clearest current illustration — opened in December 2025, tenth in the country by seats within eight months of operation, and adding metropolitan capacity in the same period that national passenger growth slowed to 1.44 per cent. Over a decade that infrastructure will look prescient. Over four quarters it puts pressure on fares.
The constructive frame is that this is what the maturing phase of an aviation market looks like, and India is entering it from a position of strength rather than distress. A ninety per cent share held by two groups gives the sector the balance-sheet depth to absorb a soft patch without the disorderly exits that marked earlier cycles — and the regulatory task, correspondingly, is to keep slot allocation and route access genuinely contestable so that concentration does not harden into pricing power once demand recovers. Meanwhile the capacity being added is not idle: it is the precondition for growth in tier-two connectivity, for international routes flown from Indian hubs rather than through foreign ones, and for cargo. The gap between 6.5 and 1.44 is uncomfortable for a quarterly result. It is exactly the right position to be in when demand turns.
