KAYAK’s top tips for finding a cheap flight from London Heathrow Airport to Sylhet

  • Looking for a cheap flight? 25% of our users found flights on this route for $1,025 or less round-trip.
  • The metropolitan city of Sylhet is situated in north-eastern Bangladesh, and Sylhet Osmani International Airport (ZYL) is the gateway to the region. Biman Bangladesh Airlines uses Sylhet Osmani Airport as a hub of operations and offers uninterrupted flight service from London Heathrow Airport (LHR) to the city. Turkish Airlines and Etihad are other air carriers using this route.
  • It’s going to be a long flight with two stopovers involved. An airport lounge offers a great opportunity to enjoy some complimentary food and beverages amid a relaxed, comfortable setting. You can find Club Aspire Lounge at Gate 18, Level 2, Terminal 5 and Plaza Premium Lounge at Gate A16, Level 4, Terminal 2 of Heathrow Airport.

  • Public transport isn’t your best option when packing heavy, but it may still be more convenient than driving or using airport parking at London Heathrow. Heathrow Express trains run directly from London Paddington station every 15min and reach the airport in less than 20min. Express anytime return tickets cost about £37 and anytime one-way tickets go for approx. £25.
  • If you’re not in the mood for long security queues, pre-book the exclusive security service FastTrack and dispense with wait times once you arrive at London Heathrow Airport. Book yours using the London Heathrow app to take advantage of any discounts or other specials offered by airport retailers. At the very least, you’ll have access to live flight data at your fingertips.

The food quality could have been a little better. Not sure if the flight was late due to weather but that was another thing. Overall it was a good experience.

The food quality could have been a little better. Not sure if the flight was late due to weather but that was another thing. Overall it was a good experience.

It was ok. I wish if they could maintain the time.

Internal air serrulation was poor, felt suffocated after a while. Food was horrible. Seats were not comfortable at all, no leg or arm stretch room at all, even though I am not a big person at all. Dhaka transit passengers' waiting area was also horrible, dirty and unfriendly service. Middle of the journey opening previously checked in baggage was extremely unpleasant experience. I never experienced anything like this before in my 30+ years airplane journey experience.

I like food, look for extra meals or foods please

Late Biman. I will never ever go with Biman again.

There was a lot of kindness on the part of the crew. There was a strong smell throughout the plane.
