Inexpensive and available around the clock, taxis are the most convenient way to get between downtown and the airport. Make sure to have some baht on hand to pay for your taxi. Get a taxi by heading to one of the taxi counters on Level 1, near Entrances 3, 4, 7, and 8. State your destination to the dispatcher at the counter, who will lead you to your taxi. Allow 30 to 90 minutes to get downtown, depending on traffic. A trip downtown will cost between B250 and B300, plus any expressway tolls. Avoid drivers who insist on a fixed price or refuse to turn on their meters.
The Airport Rail Link system is your best option during rush hour. The express train (B150) takes 15 minutes to reach Makkasan Terminal, next to the Phetchaburi MRT subway stop. A local train (B65) that takes 23 minutes stops at the Phaya Thai BTS Station, convenient for those staying on the Skytrain line. The entrance to the system is on the airport's lower level.
Buses and minivans headed for Bangkok depart from the Airport Bus Station, which is reached in 10 minutes via a free shuttle bus you can catch front of the airport.
