India’s 10 Longest Non-Stop Flights

by Staff

One route makes the world’s top 10 longest list.


  • As expected, Bengaluru to San Francisco is India’s longest non-stop route.
  • Yet it is ‘only’ ninth globally.
  • United had scheduled the return of three Indian routes in March/April, all of which are already served by Air India, but they are not bookable.

Between February and June, India’s average flight distance – domestic and international combined – covers 791 miles (1,273 km). For international service, it is two-and-a-half times greater, heavily influenced, of course, by the huge amount of service to the Middle East and Southeast Asia.

India’s 10 longest non-stop routes

They are summarized in the following table. The order will change when Air India finally announces its coming routes to Dallas, Los Angeles, and Seattle. I will update the table as and when it happens.

These were its busiest routes in the year to October.

Notice Bengaluru to San Francisco, comfortably India’s longest non-stop airport pair. Despite the enormous length, it ‘only’ ranks ninth globally for non-stop flights. Number eight is Singapore to Los Angeles, which covers 0.79% more distance, based on GCMap information.

A note on United in India

March 31, the day northern airlines will switch to summer schedules, was to be significant for United’s Indian operation. Looking at its schedules from India shows Mumbai-Newark and Delhi-San Francisco were to resume then; both were last served in early 2022. They were to be followed by Delhi-Chicago O’Hare on April 1 (no joke); it was last served in January 2023.

While the trio remain scheduled in Cirium and OAG, they are not bookable, so they were not included in the table above. Do you think they will return at any point?

What do you make of it all? Let us know in the comment section.
