IndiGo to Deploy Longest Range Narrow-Body Aircraft in the World

The A321XLR represents the latest evolution in Airbus's single-aisle aircraft family with range up to 8,700 kilometers based on the seating configuration.

India’s largest airline, Indigo Airlines, has announced its second Airbus A321XLR route. The airline will fly the Delhi-Athens route, which joins the previously revealed Mumbai-Athens flights. Both routes are now open for booking, marking IndiGo’s entry into the European market with its long-range narrow-body aircraft.

The airline will operate three weekly flights from each of Delhi and Mumbai to Athens starting late January 2026. This gives Greece six total weekly flights from India on IndiGo, making Athens the carrier’s first European destination using the A321XLR.

Both of the routes will start from January 2026, subject to schedule. IndiGo is expecting to get delivery of its very first Airbus A321 XLR in December 2025. Any delays in that would mean the flights will be pushed to some other date.

The airline is due to begin the Delhi-Athens route on January 24, 2026. IndiGo will operate this route three times a week on every Wednesday, Friday, and Sunday. Flight 6E1901 leaves Delhi at 09:10 am IST and arrives in Athens at 14:25 local time. The return flight, 6E1902, departs from Athens at 16:00 local time and reaches Delhi at 03:10 am IST the next day.

Though the A321XLRs have the range, the Delhi–Athens route will need a detour to avoid Pakistani airspace. January 2026 is still away, but by then, IndiGo will likely have to finalize its optimal routing plan. IndiGo will have to potentially fly via the Arabian Sea and the Middle East in case the Pakistani airspace remains closed.
