Bangkok Suvarnabhumi (BKK) Bangkok Don Mueang (DMK)
Suvarnabhumi to Don Mueang is 50 km across Bangkok — brutal in rush hour. Free AOT inter-airport shuttle bus for connecting passengers is the go-to; taxi is faster off-peak.

Stay overnight in Bangkok?
If your connection is 8+ hours or overnight, a hotel between the two airports beats an airport chair.
Frequently asked questions
How long does BKK to DMK take?
Taxi off-peak: 45-75 minutes. Rush hour (07:00-10:00, 16:00-19:30): 90-120 minutes. Free AOT shuttle: 60-120 minutes depending on traffic. Public transit: 90-140 minutes with 2 transfers.
Is the BKK to DMK shuttle really free?
Yes — but only for connecting passengers with a same-day boarding pass showing both airports. Show it at BKK Level 2 Gate 3 or DMK Level 1 Gate 6. Non-connecting passengers pay taxi or Grab.
How much time between BKK and DMK?
Minimum 4 hours between arrival at first airport and departure at second. Bangkok traffic can turn a 45-minute drive into 2+ hours — add extra buffer during rush hour or Songkran.
Should I use Grab or metered taxi?
Metered taxi with expressway tolls is usually 15-20% cheaper (฿400-700 + ฿100 tolls vs Grab ฿600-900). But Grab locks in the price up front — no risk of getting scammed on rate.
