I see Indigo have announced daily services from Heathrow from 26 October. As with their Manchester and Amsterdam flights, they will use a Norse 789 aircraft, so only premium economy and economy, not business. They haven't confirmed whether this will be to Mumbai or Delhi. They took a similar approach with AMS and MAN, before confirming Mumbai. I expect this will be Mumbai too. Indigo will be cheap and shoukd keep airfares low.

More Indian operated flights means more flights for UK carriers as it's essentially a reciprocal air agreement. Both Indigo and Air India have huge aircraft orders and I expect the UK-India market to balloon in coming years. Short of non-stop flights a lot of traffic is pushed via the Gulf or mainland Europe. At an event in Delhi earlier this year, BA said it was already their second largest market after the US. Flights typically go out full with business class often sold out in advance.

I'm curious to know where they're getting their LHR slots from. They just increased their cooperation with Skyteam and perhaps a Skyteam carrier at Heathrow has done a deal. Anyone know?
