Arriving

Bangkok has two airports 46km apart — the first question is which one you are in.

Does it matter which Bangkok airport I fly into?

Yes. Full-service airlines use Suvarnabhumi; low-cost carriers mostly use Don Mueang, 46km away with no rail link of its own.

How do I get from the airport into Bangkok?

From Suvarnabhumi, the Airport Rail Link on floor B1 — or a metered taxi, which adds a THB 50 airport surcharge on top of the meter.

How much alcohol and tobacco can I bring in?

Two hundred cigarettes or 250 grams of tobacco, and under one litre of alcohol. Personal effects are duty-free up to 20,000 baht. Anything above that goes into the box customs puts before the channels — the word the department uses for the alternative is prosecution.

How do I get between Bangkok's two airports?

There is a free shuttle between Suvarnabhumi and Don Mueang, but it is not a public bus. It carries only passengers with a connecting flight at the other airport the same day, and staff check the boarding pass and passport before you board. One bus per hour, 5am to midnight, and the journey time the government publishes is one to two hours.
