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.

  • What family services are available at the airports?

    All London airports have baby changing facilities. Heathrow, Gatwick, London City Airport, and Suvarnabhumi Airport have several children’s play areas. Gatwick also has strollers available for toddlers.

  • What visa do I need to travel to Bangkok?

    If you’re a UK citizen, you can enter Thailand for 30 days without a visa. For stays beyond this, you will need to apply for a valid visa. This must be obtained prior to travel. Your passport must also be valid for at least 6 months from the date you enter the country.

  • What hotels are there on site at London’s airports?

    You can stay at a hotel if you have an early flight, so you’re not rushed for your departure. For example, Holiday Inn Express can be found at London City Airport (LCY), Courtyard by Marriott is at Luton Airport (LTN) and Aerotel is at Heathrow Airport.

  • How can I reduce my carbon emissions by taking a specific flight?

    If you want to lower your impact on the environment, you can opt for a flight that releases fewer carbon emissions. For example, KLM completes this route releasing about 60% less CO2 than some other airlines. So, rather than roughly 2,362 kg of CO2 per passenger being emitted, it releases around 943 kg.

  • Which airlines provide internet on flights from London to Bangkok?

    If you need to stay connected on your flight, you can use the KAYAK search filter to find airlines that provide internet. For example, KLM offers Wi-Fi to its passengers so that you can stay online from take-off to touchdown.

  • What is the cheapest flight from London to Bangkok?

    In the last 5 days, the lowest price for a flight from London to Bangkok was £242 for a one-way ticket and £422 for a return.

  • Which airports will I be using when flying from London to Bangkok?

    On your way to Bangkok, you’ll fly out from one of these London airports: London City, London Gatwick, or London Heathrow. You’ll be landing in one of Bangkok’s 2 airports: Bangkok Suvarnabhumi or Bangkok Don Mueang Intl.

  • Which aircraft models fly most regularly from London to Bangkok?

    We unfortunately don’t have that data for this specific route.

  • Which airline alliances offer flights from London to Bangkok?

    SkyTeam, oneworld, and Star Alliance are the airline alliances operating flights between London and Bangkok, with SkyTeam being the most commonly used for this route.

  • What is the most popular stopover when flying to Bangkok from London?

    Abu Dhabi is the most popular stopover city among KAYAK users travelling from London to Bangkok.

  • How does KAYAK find such low prices on flights from London to Bangkok?

    KAYAK is a travel search engine. That means we look across the web to find the best prices we can find for our users. With over 2 billion flight queries processed yearly, we are able to display a variety of prices and options on flights from London to Bangkok.

  • How does KAYAK's flight Price Forecast tool help me choose the right time to buy my flight ticket from London to Bangkok?

    KAYAK’s flight Price Forecast tool uses historical data to determine whether the price for a flight to Bangkok from London is likely to change within 7 days, so travelers know whether to wait or book now.

  • What is the Hacker Fare option on flights from London to Bangkok?

    Hacker Fares allow you to combine one-way tickets in order to save you money over a traditional return ticket. You could then fly to Bangkok with an airline and back to London with another airline.

  • What is KAYAK's "flexible dates" feature and why should I care when looking for a flight from London to Bangkok?

    Sometimes travel dates aren't set in stone. If your preferred travel dates have some wiggle room, flexible dates will show you all the options when flying to Bangkok from London up to 3 days before/after your preferred dates. You can then pick the flights that suit you best.

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.
  • London’s airports are very modern and offer great accessibility features for passengers with disabilities. From wheelchair-friendly toilets to hidden disability assistance, your journey through the terminal will be seamless. You should request assistance from your airline in advance and a member of staff will meet you when you get to the terminal.
  • You can travel to London’s airports from a range of cities, making them convenient departure points. You can drive to Heathrow Airport (LHR) from Swindon in around 1 hour. Gatwick Airport (LGW) is about 40 minutes from Brighton, whereas Stansted Airport (STN) is approximately 1h 30min from Norwich.
