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.

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.

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.

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.

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.

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.

Avangard Capsule Hotel has queen-sized sleep capsules with charging sockets, reading lights, and a locker.

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.
