Suvarnabhumi Airport places the Airport Rail Link station on Level B1 of the main terminal and lists operating hours of 05:30 to 24:00.
Find the station
Follow Airport Rail Link signs down to B1. If you arrive near midnight, verify the last-train timing before assuming rail is available.
Into Bangkok
The line runs toward Phaya Thai with connections into Bangkok’s urban rail network.
Taxi alternative
Official taxis operate 24 hours from Level 1 and may be simpler for groups, late arrivals or hotels away from rail.
Know the station level and service window
Suvarnabhumi places the Airport Rail Link station on Level B1 and currently lists operating hours of 05:30–24:00. That matters for very early arrivals and late-night landings. If the rail service does not fit your schedule, compare the official taxi area and other ground options rather than assuming a train will be available at every flight time.
Sources and verification
Time-sensitive airport, airline, visa, security and transport details should always be confirmed with the relevant official source before travel.
