Upgrade & Award Space from Ko Samui (USM)

Koh Samui Airport (USM) is a small station in Ko Samui, TH with nonstop service to 9 destinations, served by Bangkok Airways and Scoot. Because the schedule is limited, an upgrade or award opening on a Bangkok flight rarely lasts. 2LNR checks every USM nonstop for confirmed availability, so a rare opening doesn't go unnoticed.

Data current as of July 21, 2026, refreshed on an ongoing basis as new schedules and seats are confirmed.
