IndiGo Launches Non-Stop Delhi-London Heathrow Flights From February 2026

IndiGo is the new kid on the block in the European aviation landscape. The Indian low-cost carrier after having taking over a massive chunk of domestic capacity has started in 2025 its expansion into long-haul flights with services to Europe. The new year will continue to see IndiGo expand its European network as early as February with a London UK flight.

IndiGo Pushes Further Into Europe With London Heathrow Entry

London is a key destination for any airline operating long haul services globally. The city still is a magnet for investment, tourism and immigration. That initial statement is all the more true if contextualized to an Indian carrier and the massive demand there is between UK and India.

IndiGo already operates a London service from Mumbai, it launched in 2025. However, that flight, 6E001, serves the southern airport of London Gatwick and not the mega-hub that is London Heathrow.

Starting February 2nd 2026 IndiGo will have its first London Heathrow service. From such day forward, IndiGo flight 6E003 will connect London Heathrow and New Delhi five times per week. Let’s get into the details of it.

Boeing 787-9 Wet-Lease From Norse Atlantic Airways Enables Interim Long-Haul Growth

All of IndiGo’s European expansion is made possible by a fleet of Boeing 787-9s. They were wet leased from Norwegian low-cost carrier Norse Atlantic.

IndiGo saw the conditions were right to enter the European market with its own flights and didn’t want to wait for its own ordered planes to arrive.

Possibly the idea was to attack the market before Air India would regroup and build up steam. Establishing a strong presence would make them resilient to the return of the TATA group airline.

The wet-lease agreement was a deal that made all parties happy. IndiGo got its shot at operating flights to Europe immediately. Norse on the other hand made some easy cash which it dearly needed to keep afloat.

Actually, the wet lease agreement with IndiGo is proving to make more money than it core business of operating commercial low-cost long haul flights.

A Temporary Widebody Solution Ahead of IndiGo’s Airbus A350 Deliveries

IndiGo took into its operations 5 Boeing 787-9 from Norse Atlantic and is currently using them for all of its long haul operations to Europe from Delhi and Mumbai.

This, however, is only a temporary solution for the airline as it will eventually hit the ceiling on how many flights it can operate with such a limited number of planes.

To continue expanding, which I’m certain IndiGo is keen on, more long haul planes will be needed. Those planes are in the Airbus backlog under the form of A350-900 orders. Once those planes arrive there will no longer be the necessity for the Boeing 787-9s.

Delhi-London Heathrow to Launch on 2 February 2026

Unsurprisingly IndiGo is doubling down on the UK as a destination. As I mentioned above, there is massive demand for flights between India and the UK for socio-economic ties linking the regions.

Following the initial 3 services IndiGo launched to the UK it is now getting a shot at serving the crown jewel of European airports: London Heathrow. Serving flights to LHR is of huge importance from both an operational and status standpoint.

The new flight, 6E003, will launch on February 2nd 2026 with five weekly services, every:

• Monday
• Tuesday
• Thursday
• Friday
• Saturday

As for the timing, here’s how it’ll work:

Sector	Flight no.	Departure	Arrival
Delhi – London	6E003	09:40	14:55
London – Delhi	6E004	17:15	08:15 (+1)

As covered the aircraft for flight is one of the 5 Boeing 787-9 IndiGo wet leases from Norse Atlantic. These planes retained the Norse interior which works quite well for IndiGo in a 2 class rather dense configuration. Each 787-9 is fitted with 338 seats split in:

• 56 Premium Economy in a 2-3-2 setup
• 282 Economy Class seats in a 3-3-3 setup

Fourth UK Route and Sixth European Destination for IndiGo

Flight 6E003 from Delhi to London Heathrow bumps up the total number of flights to the UK to 4 and 6 to Europe.

As mentioned IndiGo already serves the other major London airport of Gatwick with its service to Mumbai. The airline also established in 2025 flights to Manchester from both Mumbai and Delhi.

Outside of the UK IndiGo also launched flights within the EU. Amsterdam and Copenhagen were the first of what will certainly be an expanding list in coming years.

What Heathrow Access Means for IndiGo’s Long-Haul Ambitions

Accessing London Heathrow is a statement IndiGo put out there. It is saying with this strategic move: “We are here to stay”. Clearly the airline’s long haul ambitions will be throttled by the lack of a large wide body fleet of aircraft. However, once that hurdle is overcome I’m certain we’ll see Indigo expand in Europe, Australia and the US even more aggressively than seen so far.
