International: plan ~2.5–3 hours on busy days; domestic cabin-bag can work nearer 90–120 minutes off-peak.

European long-haul banks, Chinese leisure waves, and dense Bangkok LCC turns stack immigration and security in high season (roughly November– April) and on weekend turnarounds. International departures want about 2.5–3 hours curb-to-gate on busy days; domestic cabin-bag can work nearer 90–120 minutes when the bank is quiet. Monsoon weather and the single runway add delay risk.

International and domestic are separate landside halls — boarding pass beats any blog map.

The International Terminal handles overseas flights; the Domestic Terminal handles Thai domestic sectors. There is no published sterile shortcut between them. Screenshot the terminal from the airline app before you message Grab; a wrong-building drop on the ring road burns 15–25 minutes.

Convenience-store and Thai QSR coverage is fine; overnight dining is thin outside lounges and 24h shops.

Landside and airside 7-Eleven counters are the reliable snack and water play. Food courts cover noodles, rice plates, fried chicken, and coffee at tourist-island prices. Sit-down options thin out overnight. If you hold Priority Pass, Coral food is usually the better meal than another mediocre airside sandwich.

Coral covers both terminals; Blue Ribbon is Bangkok Airways-operated only.

Open the Priority Pass app the day you fly. International defaults: Coral Finest Vista (06:00–00:00 near Gate 11) when listed open, or Coral Executive (09:00–00:00 nearest Gate 15). Domestic defaults: Coral Executive (06:00–22:00) or Coral Beach (07:00–21:00). Blue Ribbon is Bangkok Airways operated-flight only. Max stays are typically 3 hours.
