What airports serve Heathrow to Chennai flights?
On the route to Chennai from Heathrow, you’ll depart from London Heathrow Airport (LHR), landing at Chennai International Airport (MAA) once you reach India. Heathrow is well-known as the main international airport that serves London and the UK. While it’s an extremely busy airport, it also houses the most modern facilities for air travellers. It’s just over 15 miles from London city centre, which will take just under 35min to drive, travelling along the M4-A4 route. If you prefer public transport, you can catch the Heathrow Express from Paddington Station in London. On the other side of your journey, Chennai International Airport is one of the busiest three airports in India. It’s also just about 15 miles from the city centre, and the best way to commute from the airport to central Chennai is to catch a train from the airport metro station.
Which airlines fly directly from Heathrow to Chennai?
Unfortunately, there aren’t any direct flights from Heathrow to Chennai, but the good news is that there are plenty of one-stop flights to choose from on any day of the week. The quickest route is flown by Qatar Airways, which leaves Heathrow and makes a single stopover at Doha Hamad International Airport (DOH) before flying across to Chennai overnight. The flight will take just under 14h and is the most efficient way to fly between the two cities. Two-stop routes are also available, and there isn’t much cost differential between them and the one-stop flights, so you can choose one of these too. A good choice is to catch Air India out of Heathrow, which flies to Mumbai Chhatrapati Shivaji Maharaj International (BOM), where you’ll change to GoAir for the flight to Chennai International.
