Top tips for finding a cheap flight from London to Thailand

  • If you’re travelling from London to Bangkok, there are only a handful of direct flights available on this route. You can, however, get cheap one-stop service from London Heathrow Airport (LHR) and London City Airport (LCY) with Lufthansa via Frankfurt or KLM via Amsterdam to Bangkok Suvarnabhumi Airport (BKK). It is the primary airport serving the capital city as well as the main gateway to the country.
  • Thai Airways is one of the few airlines with direct flights from London to Thailand. If you’re looking to save some money on your fare to Phuket, consider taking a flight with Thai Airways to Bangkok and catching a connecting flight from there to Phuket City.
  • Most flights from London to Thailand depart from London Heathrow Airport. From Central London, you can get there in about 15mins on the Heathrow Express from London Paddington Station. One-way tickets are approximately £22, while roundtrips cost around £37 per person. If you choose London City Airport for your flight, Docklands Light Railway (DLR) departs Bank Underground Station every 15mins and takes about 21min to the airport terminal.
  • At London City Airport, there are several ways to unwind before your long flight to Thailand. Airport lounges are fab for enjoying a meal and a drink in a relaxing ambience. Alternatively, you can enjoy some retail therapy at the Aelia duty-free shop. Aerospa offers massage therapies and beauty treatments to ensure you arrive at your destination looking and feeling your best.
  • Most of the London airports offer a fast track service to passengers on flights from London to China. It’s a great way to avoid standing in long queues at airport security checkpoints. You can pre-book fast track passes online at discounted prices or obtain them from kiosks before or after your check-in at the airport.

Never went. Got rescheduled with Phillipine Airlines to Bali, which was fine.

I am really satisfied with Eva Air and will definitely fly with them again.

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.

Service was great. Flight schedule was on time. Staffs are friendly.

This flight was even more crowded that Singapore to Taipei, an extra row of seats and an additional 4th seat in the middle made it extremely crowded. No leg room, no width for room. Terribly uncomfortable flight. The food was disgusting. We will never fly EVA Air again.

From checking at the airport to end of flights, attentive and caring personnel, comfortable seating, great food. I plan on using EVA again. Thank you, all.

Amazing flight crew 👏 one of the best in the air.

Amazing one of the best airlines i have ever traveled with. I live with medical issues called psoriatic arthritis and was in pain on the flight. The flight crew made sure I had fresh ice pack ever hour. Going above an beyond with service and care ⭐️⭐️⭐️⭐️⭐️.

We were very impressed with the modern plane its amenities, as well as the services of flight attendants.

I had knee surgery a few weeks prior. I was using cane walking very slow. Crew were extremely helpful

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.

Seats were uncomfortable and the vegetarian meal was awful. Some of the entertainment didn't work.

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

Flight got canceled due to Middle East conflict. Just fly hasn’t refunded me the money

Unfortunately the flight was cancelled so I never got to go

Food quality and varites were very minimum. Surprised to have no desserts. Business class tickets should have lounge access and seats selection. They should be allowed to board while people with wheel chair, secial assistance and family with childrem.

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 !

On this flight...fine. The one from India to Abu Dahbi, awful.

We have paid premium price for a business class Cabinet and we have received the old 777 with the following apart business class that is not to standard. It was very disappointing and it’s a very bad reputation for a premium airline company. This aeroplane should be the commission from being as a business class. We will pass this knowledge to our colleagues because the quality of business class in Etihad is not consistent and it is a lucky dip that sometimes you’re getting a good aeroplane and sometimes you’re getting their 30 years old aeroplane. The crew of the aeroplane have apologise and said that they hate this aeroplane and they have complained about it multiple times as well. Obviously Etihad is putting the economy in front of the Customer Experience. For the future we will not take this risk anymore and will fly with established company like emirates.

Etihad Check In counter/Station manager in Heathrow was bothering and not helpful at all. They are rude and not customer oriented

It was an old plane with seats not comfortable and with little space for the legs. I must say that the previous flight I had was amazing on a very comfortable new plane

Very disappointing #1 - You have to pay extra to use the business lounge, or else you sit in the cold airport for 7 hours and fall sick #2 - Did an awful job with boarding, they turned on the "last call" notice on the monitor made the passengers come running to the gate, once the passengers came close the crew would tell them - hey we are not boarding yet, this included passengers with children also, this was happening all the time, it was pitiful to see #3 - Did not have the courtesy for the passengers in the business class, there is a reasons why people choose business class, because they need to get to work, that means sleep is very important for them, in the business class, the crew members would themselves cause so much noise by closing the door in a loud way, once the crew member does it then the other passengers are also doing it, #4 - the food did not smell good, #5 - The Abu Dhabi airport is small, so not a whole lot to do, especially when the layover is 7+ hours. #6 - Did not provide the slippers with pajamas, #7 - also the pajamas also I had to ask, only after asking it was provided. #8- Asked for an extra pillow because the pillow they provided was not tall enough, the crew member said there was no additional pillow and gave me something like a blanket, I tried my best to use that as a pillow, but my head kept on sliding and that messed up my sleep and did not get deep thorough sleep Overall the airlines did not have an understanding of how to care for the passengers, especially the business class ones. Overall it was a bad experience, I would much rather spend the money with Qatar airways, the experience with Qatar is so much better.

While boarding at PVG, there was a ticket checking at the gate, then there was another ticket checking at the bottom of the escalator, which created quite a dangerous congestion. Not sure which idiot made this absolutely unnecessary arrangement.

While boarding at PVG, there was a ticket checking by the gate, then there was another ticket checking right at the bottom of the escalator, which created quite a dangerous congestion. Don't understand why the duplication?

I was traveling alone with an infant, so the crew was incredibly helpful. Both the international and subsequent domestic flights were impeccable.

Plane was good. But food was bad and air host was so rude. I will never fly with China Eastern again

The flight was delayed by 2 hours, although to their credit they delayed my connecting flight so people could reach it. Also their site is a nightmare to navigate on a phone. Everything else was good.

The ticket was last minute buy so no concerns about the pricing this time, but the crew in general could have been more accommodating, helpful.

CTU-KMG-CNX with 1.5 hr connection at KMG. Doable but just barely bc immigration exit from China is at the last flight leg, here: KMG to CNX. We hauled out of the domestic terminal to reenter at the international departures (luggage checked thru to CNX thankfully). Immigration had only two agents, even though KMG gets a HUGE number of foreigners. It took forever for such a shot line. Then security also took a while, so I just just made the connection. Recommend if you exit China with domestic international transfer, plan for 2+ hrs to avoid a heart attack. Airline personnel don’t suffer if you miss the flight, you do. Plan accordingly.

China Eastern as a member of Sky Alliance airlines should have the same standards overall of their partners, Besides the seats comforts everything else is bellow the standard for a business class travelers. A BIG ISSUE FOR NON-CHINESE PASSENGERS IS THE ABILITY TO CHECK IN ONLINE, by making so difficult or almost impossible there is no chance to get a seat assignment ahead of time then go to the airport and get what is left. THIS IS NOT a SKY TEAM modality.

2 parts to the journey. First leg covered in a newer plane with decent staff + POOR FOOD QUALITY but the second half didn’t leave a positive impression at all as the plane itself was an older built and the crew didn’t serve properly. Language is an issue with China Eastern flights as always, but unmotivated crew just makes it even bad.

I alrady responded to this request, and expllaned at length that this was the worst flying experience in my 77 years. I will NEVER fly BA again.

Airbus A350 is poorly designed for wheelchair users and reduced mobility passengers. The angle of the pods makes it awkward to transfer. I was able to but I have ab stability. It could be a real challenge for people with more severe mobility impairments. You'd think Airbus would have come up with a solution for this or thought more about us disabled folks more when designing this aircraft.

The crew has always been great on BA. They are very friendly and accommodating. I like that they have vegetarian options already in the menu. And the free wine is a nice perk.) I noticed (both directions of my trip) minor upgrades/ replacements needed on the plane itself (touch screen didn't work with touch; bathroom light didn't go on). However, this is one of my favorite airlines.

It was not British Air, we were put onto Air Portugal for our London to Lisbon leg.

Everything was spectacular except the boarding. It was just a mob of people while all groups were called over the public address system.

BA code for a Vueling flight. All god but the temperature in the plane (too hot when engine not running but otherwise ok)

The Britts are wonderful to fly with and the crew were very hospitable. Again, I really wish they had been able to retrieve my carryon bag from baggage claim before the flight so I could be in a less worrisome state of mind, but that's not on them. I completely understand. The window seats with the dimmable windows were very cool!

There was a delay for the San Francisco-London flight, but we were all informed via text and email. The staff was very friendly and nice and the food was good. I do recommend that the airline offer something without eggs or something vegan for the vegetarian meal option. A lot of Indians are lacto-vegetarian, while some could be allergic to eggs/dairy.

food options were terrible. for a 10-hour flight, there should be 2 decent meals. Also, flight attendants should come around with drinks more than just at the meals.

Smooth flight. The seats were comfortable but the reclining mechanism didn't work very well. My wife's seat required the flight attendant to push the seat forward while she pushed the button. The leg support didn't want to return to its home under the seat. I ordered the diabetic meal which was full of carbs. It was low in sugar but carbs turn into sugar so was it really diabetic? Overall the flight was pleasant, long but pleasant.
