Mumbai to London is one of India's busiest long-haul routes, and one of the few where you actually get a choice of nonstop flights. The calculator above is already set to it; here is everything else worth knowing, from the time in the air to what waits for you at Heathrow.
How long is the Mumbai to London flight?
The great-circle distance is about 7,213 km, and a nonstop takes roughly nine and a half to ten hours. Our estimate comes out around 9h 30m, while airlines usually schedule closer to 9h 55m westbound. The return to Mumbai is often a touch quicker, because you fly east with the wind rather than against it, which is the jet stream effect at work.
What time will you land?
This is the part that trips people up, because London runs four and a half hours behind India in the British summer and five and a half behind in winter. So the clock barely seems to move on the way out. Take a common mid-afternoon departure: leave Mumbai at 14:00, add about ten hours in the air, and you would land at midnight India time, but on the London clock that is only about 19:30 in summer or 18:30 in winter. A daytime flight from Mumbai therefore lands the same evening in London, with a whole night still ahead of you. Overnight departures, which several of these flights are, leave late and land in the London morning. The calculator above already has the route loaded, so put in your real departure time and it will tell you the exact local arrival and whether the date rolls over.
Which airlines fly nonstop?
As of 2026, four airlines fly Mumbai to London Heathrow without a stop: Air India, British Airways, Virgin Atlantic and IndiGo, which added the route with leased wide-body jets in late 2025. Air India and IndiGo are often among the more competitively priced. If you are willing to add a few hours for a lower fare, there are also plenty of one-stop options through the Gulf with Emirates, Etihad and Qatar Airways, which can work out cheaper, especially outside the peak season. Routes and carriers on this pair do change, so it is worth a quick check when you book.
IndiGo began its daily Mumbai to Heathrow service on 26 October 2025, per its own announcement and Simple Flying.
What the flight itself is like
Ten hours sounds daunting the first time, but it settles into a rhythm. On a daytime departure you get a meal about an hour in, a long quiet middle stretch for films or sleep, and a second, lighter meal before landing. On an overnight flight the crew usually serve dinner soon after take-off, dim the cabin for the bulk of the flight, and wake you with breakfast an hour or so out. Either way it is a single film-and-a-sleep sort of trip rather than an endurance test. If it is your first long-haul, a window seat ahead of the wing is the easiest place to sleep, and our guide on choosing the best seat runs through the trade-offs. Because you cross four and a half time zones, expect some mild jet lag on arrival, worse coming back east to Mumbai than going out; the jet lag guide has a simple plan for it.
When to fly, and when to book
Fares peak in the British summer, roughly June to August, and again over the Christmas and New Year weeks, when the Indian diaspora travels in force. They ease in the quieter shoulder weeks of spring and autumn, and January and February are usually the cheapest of all. For this route, booking two to four months ahead is the usual sweet spot, longer if you are travelling at a peak, when seats on the nonstops fill early and the fares only climb. Our guide on the best time to book international flights goes into the patterns in more detail.
At Mumbai airport, before you go
International flights to London leave from Terminal 2 at Chhatrapati Shivaji Maharaj International Airport, the big integrated terminal, so head there rather than the domestic Terminal 1. Give yourself three to four hours before departure on this route: check-in for a full long-haul opens early and the queues at check-in, emigration and security all take time at peak hours, especially on the late-evening bank of departures when several long-haul flights leave together. Do your web check-in the day before to lock in a seat and save a queue, and keep your passport, visa and boarding pass together. The order at an Indian airport catches first-timers out: after check-in you clear emigration, where an officer stamps you out of the country, before the security check, not after. Once you are through security you are landside in the duty-free hall with time for a coffee before boarding.
Landing at Heathrow
Heathrow is large and split across terminals, so check yours before you fly. Air India uses Terminal 2, the Star Alliance terminal, Virgin Atlantic uses Terminal 3, and British Airways Terminal 5. Terminal assignments do move around, though, so go by the one printed on your boarding pass. Immigration queues can be long at peak times, so leave plenty of room if you have an onward connection. Once you are through, you have a few ways into central London. The Heathrow Express is the fastest, around fifteen minutes to Paddington but the priciest; the Elizabeth line is slower at roughly forty minutes, far cheaper, and runs straight across the city; the Piccadilly line on the Underground is cheaper still and slowest. For most arrivals landing tired with luggage, the Elizabeth line is the sensible middle. If someone is meeting you by car, agree a terminal and a pickup point before you fly, because Heathrow's drop-off and short-stay charges add up quickly.
Before you fly
Indian passport holders need a UK visa for this trip, so sort that well in advance. It is also worth lining up an eSIM you can switch on as you land, so you are not hunting for a SIM at the airport, and checking your airline's baggage allowance, since it varies by fare. If this is your first long-haul, the first-time flyer guide covers the airport side end to end.
Is the nonstop worth it over a Gulf connection?
It depends on what you value. A nonstop saves you three to five hours and the hassle of changing planes, which matters a lot on a daytime work trip or when you are travelling with children. A one-stop through Dubai, Doha or Abu Dhabi is often cheaper, and can come with a nicer seat or better service for the money, at the cost of those extra hours and a second take-off and landing. The simple rule: if the saving is small, take the nonstop; if it is large and you have time to spare, a single-ticket connection through the Gulf is a sensible trade. Our guide on direct versus connecting flights walks through how to weigh it.
