Gatwick and Heathrow are both accessible by road in under one hour. However, traffic conditions can slow down your journey to the airport. When you land in Bangkok, you will usually touch down at Bangkok Suvarnabhumi Airport (BKK), which is located around a 30 minutes to one hour journey from Bangkok city centre. Passengers can take the City Line Airport Rail link from the terminals and reach the city centre in roughly 30 minutes.

Question 12

Accepted Answer

When you book flights from London to Bangkok, you will usually fly from either London Heathrow or from London Gatwick. Both of these airports are international travel hubs and can be extremely crowded, especially during peak hours. Gatwick may be slightly less crowded than Heathrow, however, it is still advisable to arrive at both airports 3 hours before your departure time. This will give you time to queue at security and check-in. Passengers staying on the north side of London will be best served by booking flights from Heathrow. Heathrow is located in London’s northwest. Meanwhile, if you are travelling from the south, Gatwick is likely to be a better option for you. Although Bangkok is served by two major international airports, flights from London to Bangkok usually land at Bangkok Suvarnabhumi Airport.
