IndiGo expands with New Delhi-London Heathrow route 2026

After years of connecting flights, awkward layovers, and airport meals you only eat because you’ve got nothing else to do, IndiGo is finally going nonstop from Delhi to London Heathrow. Mark your calendars (or your group chat): the first flight takes off on 2nd February 2026, and yes — it’s direct, proper, and very much long-haul.

The route will operate five times a week, giving travellers a new, straightforward way to get from India’s capital to the UK’s busiest airport without collecting extra boarding passes along the way.

And because this is IndiGo doing long-haul its own way, the flights will be operated using Boeing 787 Dreamliners leased from Norse Atlantic Airways. Think widebody comfort, modern cabins, and enough range to cross continents without breaking a sweat.

Stretch or Don’t Stretch — Your Call

Onboard, passengers will find a dual-class configuration: standard Economy and IndiGoStretch, the airline’s more spacious premium offering. It’s designed for travellers who want a bit more legroom, a bit more comfort, and a bit less of that “I’ve been folded into this seat since take-off” feeling by the time you reach London.

This isn’t first class luxury with caviar and pyjamas, but it is a clear upgrade for long-haul travel — and exactly the kind of product you want on a nine-hour flight that lands at Heathrow before your body clock has fully caught up with reality.

London, But Make It Twelve Flights a Week

With the launch of the Delhi–Heathrow route, IndiGo will operate a total of 12 weekly flights to London. That includes its existing daily Mumbai–Heathrow service, which has already proven there’s plenty of demand between India and the UK.

In other words, London is no longer just a side quest for IndiGo — it’s becoming a key destination. More frequencies mean more flexibility, better connection options, and fewer moments of staring at calendars trying to make flight dates work.

For business travellers, families, students, and anyone who’s ever needed to move between India and the UK for reasons that go far beyond sightseeing, that extra capacity actually matters.

Delhi Is Becoming IndiGo’s Long-Haul Playground

This new route also fits neatly into IndiGo’s rapidly expanding international network from Delhi, which is starting to look less like a regional hub and more like a serious long-haul launchpad.

Over the past year, the airline has been busy adding destinations such as Bali, Krabi, Hanoi, Guangzhou and Manchester, with Athens already lined up for January 2026. It’s a route map that says: beaches, culture, business, diaspora travel — and yes, some very good food at the other end.

London Heathrow slots are notoriously hard to come by, so this launch isn’t just another route announcement. It’s a signal that IndiGo is playing a much bigger international game now, and it’s doing so with confidence.

Why This Route Makes Perfect Sense

Demand between India and the UK has always been strong — and not just in peak tourist seasons. Business travel, family visits, education, and year-round connectivity keep planes full in both directions.

A direct Delhi–Heathrow service removes friction from the journey, cuts travel time, and makes life easier for passengers who don’t want to change planes somewhere in the middle of the night.

IndiGo says the new route will support business, tourism and family travel, and that’s airline speak for: “People want this, and they’ve wanted it for a long time.”

The Bigger Picture

Yes, the route is still subject to regulatory approvals — but assuming everything goes as planned, this launch marks another milestone in IndiGo’s evolution from short-haul powerhouse to long-haul contender.

More widebody flights, more global destinations, and more presence at major hubs like Heathrow all point to an airline that’s steadily rewriting its own playbook.

For passengers, it means more choice. For competitors, it means more competition. And for anyone flying between Delhi and London in 2026, it means one less layover, one less sprint through a transfer terminal, and one very welcome nonstop option.

Sometimes progress really is as simple as getting on a plane in Delhi and stepping off in London — no detours required.
