Hi,
So, it looks like it’ll be "Krung Thep Aphiwat" station.
- 5 stops to Makkasan on the Airport Rail Link, then transfer to the blue metro line from Petchaburi (the station, not the city ;)) for 10 stops north to Krung Thep Aphiwat. Around 1h30 total travel time. Expect some corridors.
- Free airport shuttle to the bus terminal (quick since it’s nearby), then bus S6 to Krung Thep Aphiwat (runs until 10 PM). The cheapest option but also the longest—anywhere from 1h30 to 2h30 depending on the time.
- Taxi from the departures level (only if you know what you’re doing) or queue at the official taxi counter. Timing depends on traffic (worst during 6:30–10 AM and 3–8 PM). Budget for the "airport pickup fee" (only applies if you use the official counter) on top of the metered fare, plus expressway tolls paid by you as you go (a common way to break a big 1000-baht note, since drivers usually don’t carry much change for safety).
Refuse any driver who asks for a fixed price—metered fare is the rule.
