India’s Longest & Shortest Flights in Summer 2025: Key Airline & Route Insights

Leading the way, IndiGo will operate the highest number of flights with 13,896 departures, followed by Air India, which plans 3,720 flights.

As the Northern Summer Schedule for 2025 officially kicked off on Sunday, March 30, 2025, a series of new flight launches, route changes, and operational shifts have been introduced across Indian airlines and airports.

According to the Directorate General of Civil Aviation (DGCA), a total of 25,610 weekly flights have been approved for the summer season. However, data from Cirium, an aviation analytics company, indicates that 23,234 flights are scheduled to take place across airlines in April 2025.

It’s important to note that many of these flights will start progressively throughout the season rather than from day one.

Leading the way, IndiGo will operate the highest number of flights with 13,896 departures, followed by Air India, which plans 3,720 flights. Air India Express, which is experiencing significant growth, has been allocated 3,375 slots, with around 2,715 planned departures.

This route spans 2,481 km, with a flight time of 3 hours and 35 minutes to Port Blair and 3 hours and 50 minutes on the return leg. Air India operates this route using its A320 aircraft.

On the other end of the spectrum, the shortest domestic flights in India are a tie between Diu-Keshod-Diu and Silchar-Imphal-Silchar, each covering just 95 km. These flights are operated exclusively by Alliance Air, using ATR 72-600 aircraft. The Diu-Keshod-Diu flight operates three times a week, while Silchar-Imphal-Silchar runs twice a week.

Airport Operations and Developments

Delhi remains the busiest airport with 3,480 weekly departures. Bengaluru has overtaken Mumbai as the second-busiest airport, with 2,378 departures scheduled, while Mumbai follows with 2,284 departures. Although Bengaluru has experienced rapid growth, its network includes smaller ATR and narrowbody aircraft, resulting in fewer total seats compared to Mumbai, which offers more high-capacity flights.

At Hyderabad and Pune airports, both host eight domestic carriers, offering a wide range of flight options. Interestingly, FlyBig and IndiaOne are absent from these airports.

Out of the 119 airports with confirmed schedules, 41 are served by only one airline. These airports are at risk of service disruptions if the operating carrier faces financial difficulties. Regional airports in India have historically been vulnerable to closure, and these low-frequency routes may face similar challenges. At seven of the top 10 airports in the country, IndiGo holds a frequency share of over 50%.
