Upgrade & Award Space from Chiang Rai (CEI)

Chiang Rai International Airport (CEI) is a small station in Chiang Rai, TH with nonstop service to 4 destinations, served by Royal Flying Doctor Service, Hahn Air Systems, and Thai Vietjet Air. Because the schedule is limited, an upgrade or award opening on a Bangkok flight rarely lasts. 2LNR checks every CEI 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.
