  • Can I book a direct flight from London Heathrow (LHR) to Bangkok Suvarnabhumi International Airport (BKK)?

    Thailand’s national airline, Thai Airways and the Taiwanese EVA Air both operate direct flights from LHR to BKK throughout the week. The airline operates out of London Heathrow. There are other, connecting flights operated out of LHR by airlines such as Swiss Air, KLM Royal Dutch Airlines and Lufthansa that may provide more flexibility.

  • Is it possible to exchange currency on arrival into Bangkok Suvarnabhumi International Airport?

    Yes, it is possible. There are currency exchange bureaus, operated by Siam Commercial Bank and Kasikorn Bank, that are located in the Arrivals hall on the second floor and the Meet and Greet area on the third floor of the Main Terminal building. These exchange kiosks are open 24/7. Alternatively, there are non-bank exchange booths that are located next to the Aerolink train platform and these are open from around 06:00 to 00:00.

  • Is there an airport hotel at BKK?

    If your flight from London to Bangkok arrives late in the evening or has been delayed you could always book into the Novotel Suvarnabhumi Airport Hotel, which is located a 3-minute walk from the main airport terminal and can be accessed via an underground walkway. Staying here will save on navigating the traffic into the city at night.

  • How do I get from Bangkok Suvarnabhumi International Airport into the city and beyond?

    There is an Airport Rail Link train into the city which avoids the traffic on the roads. This service costs between ฿15 (around £0.37) and ฿45 (around £1) depending on the length of the journey. The journey into the city will take around 30min. Alternatively you can take advantage of the airport taxi service, booking a taxi at the desk in Terminal 1 before joining the queue for the next available car. This service is slightly more expensive and will be in the region of about ฿240 (around £6).

Amazing customer service. BUT!! It would be nice if the flight attendants SMILE a little more, I know they are doing their job, but it is importantly to smile back and be warm to passengers. Nobody is trying to hit on them, it’s just being polite. So, please Taiwanese flight attendants: SMILE MORE WHEN YOU INTERACT WITH PAYING CUSTOMERS

What could have been better, was we were delayed from takeoff for two hours. Initially we were informed that we were delayed for refueling. Then we taxied out on the tarmac, then just waited there for a long time, with no explanation of the delay. Were we just waiting on takeoff clearance or was there some other reason for the delay? The pilot, nor none of the crew informed us passengers. That was not good customer service. That needs to be improved, whenever a delay, inform the passengers for the reason.

More new and classic movies in English. Boarding was a bit chaotic. Nore, clearer information during boarding to customers.

More seat space More bathrooms Charging outlets Plane was old

It was easy going check in was easy and pretty fast entertainment was up to date on movies and food was ok

The soft service on EVA was superb from the quick and attentive flight attendants, to the turn down service, and excellent food. This all made my 11 hour flight very comfortable and relaxing.

Flight attendants were very helpful and nice. Would be nice to board on time.

I love EVA airline, but the KAYAK website for not in emergency, urgency and personal issues. For instance, on January 5/2026 with already booked the flight, I have a 15 hours of delay between airport when booked before as my choice. But if I want to go back home (U.S) early, then I have to contact the KAYAK office at I was in other country without phone service and nothing that EVA can do for me. Even I offered to pay more to change from another flight to go to the U.S early, not wasting at15 hours of delay, but EVA could not help me until I call KAYAK at an Island of nation. No office of KAYAK from any nation and times of difference in the world. However, everything and everyone is the best. Therefore, please KAYAK making much more easy for both the airline and passenger in some issues at the middle of nowhere in some country when no need to call KAYAK for some emergency, urgency, sick, etc or personal reference. Please, please, please no need to call KAYAK office for any changes of flights from urgency or private.

Don’t preorder the diabetic meal if you don’t have to. Whoever creates those meals thinks everyone loves fish, and hates seasoning. In a world where we can find diabetic friendly candy and low card bread, it’s surprising that places are still serving flavorless gelatin and rice cakes. Boarding in Taipei was chaos. They tried to form a line but didn’t manage it. So once the gate was opened, the line didn’t matter and everyone just mobbed to the front.

Excess baggage fees are outrageous ($250 per bag). Flight crew and planes are nice.
