India’s Largest Airline Steps Into Long-Haul Territory

Starting October 26, 2025, IndiGo will operate daily direct flights from Delhi to London Heathrow, signaling a bold shift from regional low-cost travel to long-haul international service. This strategic leap marks the airline's biggest expansion into global markets since its inception.

The flights will be operated using the Boeing 787-9 Dreamliner, offering improved range, comfort, and capacity—pushing IndiGo into a new competitive tier alongside full-service international carriers.

Flight Schedule: Delhi to London, Daily

IndiGo has announced a new daily flight schedule between Delhi and London Heathrow, pending final regulatory approvals. Flight 6E 1851 will depart from Delhi at 1:10 PM IST and arrive in London at 5:45 PM BST. The return flight, 6E 1852, will depart from London Heathrow at 8:15 PM BST and land in Delhi at 8:55 AM IST the following day.

This new route taps into one of the most lucrative and in-demand international corridors—India to the UK—offering a direct link at a time when global capacity is still rebounding.

Why This Move Is a Game-Changer for B2B Travel

For travel agents, consolidators, and corporate planners, this launch opens exciting opportunities:

B787 Dreamliner Comfort: Designed for long-haul comfort with quieter cabins, better air quality, and mood lighting.
