FAQs - booking Thailand flights

  • Do you need a tourist visa to visit Thailand coming from Boston?

    No, tourist visas are not required for U.S. citizens traveling to Thailand.

The fastest and cheapest way of getting to the city center from the airport is probably taking the Airport Rail Link. It takes passengers to the Phaya Thai district in central Bangkok in about half an hour, and you can expect to pay only about THB 45 (USD 1.50) for the ride.

    Hacker Fares allow you to combine one-way tickets in order to save you money over a traditional round-trip ticket. You could then fly from Boston to Thailand with an airline and back with another airline.

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

Top tips for finding cheap flights to Thailand

  • The main airport to fly into in Thailand is Suvarnabhumi Airport (BKK) in Bangkok, the capital city. This airport is closest to some of the country’s top sites like The Grand Palace, the Wat Arun Ratchawararam temple and the Temple of the Emerald Buddha.
