FAQs for booking flights from London to Bangkok

  • Which airport in London is the easiest to access?

    As the only airport within the city limits of London, London City Airport will be the easiest to access from the city centre. City buses and the Docklands Light Railway connect the rest of the city and the London Underground to the airport. Heathrow Airport comes next, due to its direct connection with the London Underground, as well as the Heathrow Express train, which can reach the airport from Paddington Station in 15min. However, if you’re travelling from south London, Gatwick might be a good option, as it is 25 miles south of the city centre (there is also the 30min Gatwick Express train from Victoria Station). Transport options to Stansted are limited unless you are travelling from the north, and the Stansted Express to Liverpool Street Station takes around 45min.

  • Are there on-site hotels at Suvarnabhumi Airport?

    If you’re feeling the jet lag, Suvarnabhumi Airport, fortunately, has three hotels within the airport. Miracle Transit Hotel is within the secure area and features a beauty salon, sauna, and spa. Boxtel has soundproofed rooms with air conditioning, a full bed, and a pillow, as well as a work desk. Avangard Capsule Hotel has queen-sized sleep capsules with charging sockets, reading lights, and a locker.

  • What are my options for transport from Suvarnabhumi Airport?

    The airport is served by city buses as well as regional buses, with connections to Pattaya, Sa Kaeo, Nong Khai, Sriracha, Rangsit, and Phra Ram. Air-conditioned Limo Buses travelling non-regular routes are also available. The Airport Rail Link train service departs from Basement B of Terminal 1 during the hours of 06:00 to 00:00, travelling to Phaya Thai Station with six stops along the way. Car hire services are available 24h, from the second floor of Terminal 1.

KAYAK’s top tips for finding a cheap flight from London to Bangkok

  • London has a whopping six airports, but Heathrow Airport (LHR), Gatwick Airport (LGW), London City Airport (LCY), and London Stansted Airport (STN) are the ones with flights to Bangkok.
  • As Heathrow is the busiest and biggest airport in the UK, make sure to arrive with time to spare – the airport’s size and traffic levels mean longer queues as well as more walking. Fast-track security access can be pre-booked at least 24h before your flight, for around £12.50.
  • Fancy a bit of reading? Newspapers and magazines can be picked up for free from the Green Bug Media stands at Gatwick.
  • Bangkok has two international airports, but flights from London now land in the newer Suvarnabhumi Airport (BKK). Suvarnabhumi Airport serves Bangkok and Samut Prakan and is the main hub for Thai Airways.
  • If you’re in need of Thai baht after landing, Kasikornbank, Siam Commercial Bank, and TMB Bank in the airport offer foreign currency exchange as well as international money transfers.
  • If you would like your journey to be as quick as possible, you can find direct flights from Heathrow to Suvarnabhumi Airport with EVA Air or Thai Airways.

Food tasted like the meat had freezer burn. Another thing all of our 4 check baggage was left somewhere and my oral medication for my diabetes was left in one of the lost luggage..most of the flight attendants did not know how to communicate in English.. the trip was a total nightmare

I put the review all together for the first review

I liked that they gave us a couple of meals and drinks but the meal was not good and not many options especially if we are seated in the back of the plane.

Again on this leg the WiFi wouldn't work. The seats were comfortable with adequate cushion and space between seats for my legs. Very nice 3-hour flight.

The flight from SEA to Taipei was on a Boeing 787-10. Economy seats were unacceptably cramped and the seats themselves were old and lacking cushion. I'm only 5'3" and couldn't cross my legs as my knees were up against the seat in front of me! I could not get WiFi to work most of the time on both flights and crew were invisible except to serve meals. The onboard entertainment also did not work reliably and was very hard to hear through the provided earbuds. The Asian vegetarian meals were interesting. I hope they can provide a fully vegan option though these meals seemed to be already. I appreciate their providing these meals options for vegans. I don't think I'll fly a 787-10 if I can help it. It was the definition of a sardine can in Economy.

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

Premium Economy seats were more comfortable than other airlines I have recently been on. Great staff. Food was unremarkable.

Very nice, I feel I got good value for the price.

Overall is good. But Asian movie selection was not great at all. And also more snack food to give out

Flight attendants are polite and pro. Missing of on flight entertainment is a big miss for a ordinary airline.

Gate and boarding processes were handled smoothly and efficiently. Both (connecting) flights departed and arrived on time. The cabin crew seemed anxious and a bit stressed/rushed. Food service was OK, but the hot food dishes were poor quality.

HAVING ANNOUNCEMENTS FOR PEOPLE TO BOARD ACCORDING TO GROUP IS ESSENTIAL N ENSURING N CUTTING OF QUEUES, EXCEPT FOR PRIORITY CLASS PASSENGERS ON A SEPARATE Q

We still get drinks and a snack. Love the gift bags too.

business class is old but still done very well by the team.

Excellent airline. The plane was clean and the staff were very attentive

Good experience although the boarding gate is at the terminal extension hence need to leave lounge to head over earlier.

Thai Royal First is very good. Easy check in , Private room in the first class lounge and escort from ticketing to the plane. Once on board crew was very polite, food was outstanding, and the ride was smooth as silk. Restrooms were especially clean. Great Experience

I'm not interested in improving the airline. Therefore, I won't explain this in more detail. Next time I'll try a different one.

The flight (boarding) was delayed by 40-50 minutes and there was very crowed. They need to improve on the timeliness & boarding process. (They asked passenger to board in groups, but the 2nd group was standing there waiting for 20 minutes!). However, services from the crew was very good, also the food was good as well. I also found the legroom was quite comfortable.

Need to improve on punctuality. My flight was delayed by 1 hour.

I payed for extra leg room but in last moment my seating place was changed and i got standard one seat. Staff was not able to do anything , so was very disappointed because of this.

It was very relaxing and staff were very quick to attend to any requests.

I booked tickets for a family of five and specifically paid extra to select our seats together. We spent nearly $1,000 extra (around $100 per seat) for extra legroom so we could sit near each other. However, despite paying for this, we ended up being separated on the flight. This caused a major issue for our family because my parents do not speak English and rely on me to translate and assist them during the journey. I do not understand why Etihad changed our reserved seats without explanation. I am extremely dissatisfied with this experience. I expect the airline to do better, and I am requesting a full refund for the seat selection fees we paid.

1 hour delay meant missed my connecting flight and 1st day of holiday

The seats seemed smaller than other business class offerings. The entertainment menu was limited. Flight crew was good.

Dear Team, I purchased a full travel package that included 2 checked bags through you and JustFly. However, when I arrived at the airport, my ticket showed 0 checked bags. Since I was traveling internationally to India with 2 bags, It was a $200 per bag at the counter, which was extremely disappointing. For an international trip, why would I ever choose a no‑bag option for only $20–$30 less? This seems like an error in the booking process, and I am requesting clarification and a resolution. I have called JustFly and on phone for 1 hr :53 min and they couldn't help till I show some kind of proof etc which isn't possible but besides that love your service and using it for years !

Early arrival. Good boarding. Deplaning this flight is very slow both coming and going. Baggage arrived quickly for Pearson

Good service. But on flight to Kochi no entertainment except in app. And no working outlets to charge phone.

No entertainment except on app. No outlets working to charge. Good service

Good flight. There were a few issues with the flat bed. It was some technical issues. Otherwise everything was good

The entertainment could have been better, better choice / better headphones, but overall very satisfied

The friendly staff. They kept time. Was suprised to get some drinks.

We did not even get on this flight as the plane never left London. I missed the email that was sent mid morning USA time, so we were not aware the flight was cancelled. There was absolutely no help from the staff at the Norse check in gates, we were told to take a picture of the board they were holding up, to try and claim our money back. We were told to book our own flights to London which ended up costing $10000 due to the last minute. And now we have to return to Miami in 2 weeks. I am not holding my breath about getting on board for that flight either.

Great experience. The flight was smooth with very little turbulence. We were in premium classic, so lots of leg room.

Didn’t know you had to pay for earbuds and food on flight. Sounds awesome and better way to not waste food or items. Comfort of flight is was amazing other than that

Unexpectedly was surprised with the space on flight in economy and the price.

I was not expecting having to pay for headphones, water and basic food in a 9 hours flight. Price for this flight was as high as any other, still I had to pay 4 lbs for a can of sprite. On top of that flight attendance gave a bothered look when I asked her for some ice for my soda. She reluctantly when to get it, brought me literally 3 cubes and walked away without looking at me to avoid another request. I couldn’t believe it. She was soooo rude. I will never book on Norse again and I will let everyone I know about this. Unforgivable, very bad customer service.

Great crew. Customer support is pretty much non existent. I had 2 tickets that were not used, the flight was overbooked. I think I should have been reimbursed for the unused tickets.

The movies were super old. The crew did not offer WATER???? 5 hours os flight and did not get WATER? Norse is the worst company I ever used and never will use again.

Why call us to board if we’re going to be made to stand in the tunnel for 20 minutes. Really hard for people with little children. Plus it took me ages to check in because my seat in Premium was overbooked so I didn’t actually have a seat. I did end up receiving my seat in Premium but there was a lot of stress and confusion beforehand. Hope is it possible to overbook seats? Especially in Premium!

The plane was a long way from departure lounge. The plane looked tired but got us there.

Lovely big plane. Excellent take off and landing. Cabin crew were so nice. Flight in time no delays

Because our ABZ-LHR flight was cancelled by BA for reasons they refuse to tell us--not weather--we did not make this flight and were booked on the following day. BA offered no assistance to us on the phone or in the airport, and we had to find a hotel at Heathrow on our own.

Horrible - flight was delayed by 6 hours - we boarded, were made to de-board due some technical fault; aircraft changed; special meals request on new flight - all went awry. Landed in Dulles airport; breezed thru immigration; as Business Class passengers or baggage was delivered almost 90 minutes after landing; air tags indicated the bags were just near the carousel but the unhelpful BA staff - Maria and Ghina refused to give any update - palming it off on some imaginary invisible “manager” despite air tags evidence showing it right there. So about 50-60 passengers waiting and getting infuriatingly impatient for their bags coz one container was not delivered. Finally after much argument by some other passengers Maria condescended to go to the “ramp” and within 5 minutes the baggage was delivered miraculously. Question is why couldn’t she have done it one hour earlier ? Poor poor experience once again on Business Class BA.

Poor service, antiquated plane with 2-3-2. B-class config upstairs. Tight and not comfortable—not what I expected for paying B-class! AND my bag didn’t make the transfer, bag will be delivered the day after it lands!

Cheap Flight Fares would not provide booking info. I canceled the reservation and we arbitrated with American Express. They provided erroneous info to Amex and it was determined that C.F.F. deserved the price of the ticket. Worse experience I've ever had.

Seating space is appalling. Seats and all surrounding area in "Economy" is built for individuals shorter than 4' 10" and below 120 lbs. Ridiculous. While I'm not expecting fine dining, the food was the worst airplane food that I can recall.

Business class lounge for my gate was closed and no email was sent, causing me to walk back and forth to different gates, etc for over 20 minutes one way. Flight entertainment was mediocre with very poor choices especially for business class cabin. Original flight was cancelled and rebooking was difficult and no reason given for cancellation.

Waiting area not big enough for all the passengers, no airport lounge.

Very comfortable flight and simple and directed one way and back. Amazing price.
