What is the best way to get in and out of airports in London and Sylhet?

Heathrow Airport lies slightly to the west of Central London and being such a busy airport, transport there is very efficient. The fastest and most convenient way is to catch the Heathrow Express, which takes about 15 minutes. Trains leave from London Paddington Station every 15 minutes. You can catch a bus from the same station, which will take about an hour to get you to Heathrow. Otherwise, a Tube train will take you there in about 50 minutes on the Piccadilly Line. Alternatively, you can drive or take a taxi to the airport in roughly 30 minutes. Once you’ve landed in Bangladesh after flights from London to Sylhet, your arrival airport is much closer to the city. It will only take you about 8 minutes to get there by taxi – unfortunately public transport isn’t available. If you’ve hired a car, you can drive yourself in the same amount of time. Which cities can you get to from Sylhet Airport? You can reach many smaller cities and towns in the surrounding northern area of Bangladesh from Sylhet Airport. We’d recommend hiring a car in advance, as public transport is mainly restricted to the cities, with infrequent buses between towns. You can drive north-east to Sunāmganj, which will take just under 1h 20min. Driving south will take you to Moulvibazar in roughly 1 hour. Closer to Sylhet is Golapganj, which you can reach in about 25 minutes. While you’re online organising your car hire, don’t forget to check on momondo for cheap flights from London to Sylhet as soon as they’re available.

Which airlines fly direct from London to Sylhet?

If you’re after direct flights from London to Sylhet, Biman Bangladesh Airlines is the carrier to choose. It offers a flight every Sunday, Wednesday, Friday, and Saturday, leaving from London Heathrow Airport (LHR). The flight will take about 9h 20min, and you’ll land at Sylhet Osmani International Airport (ZYL) in Bangladesh. The next quickest flights all make at least one stop in-between. You can depart on Qatar Airways, once again from Heathrow, and change airlines at Doha Hamad International Airport (DOH), flying with Biman Bangladesh the rest of the way to Sylhet. This will take about 13h 20min. The other relatively short London to Sylhet flights make two stops and are operated by a combination of three airlines. You’ll depart from Heathrow on Lufthansa and transfer to Qatar Airways at Frankfurt am Main Airport (FRA). From there, you’ll fly to Doha and change to Biman Bangladesh for the final leg to Sylhet.

Passengers with limited mobility or hidden disability needs can arrange for personal assistance in advance. All areas of the terminals are wheelchair-accessible.
