Upgrade & Award Space from Udon Thani (UTH)

Udon Thani International Airport (UTH) is a small station in Udon Thani, TH with nonstop service to 5 destinations, served by Royal Flying Doctor Service, Thai Lion Mentari, and Nok Air. Because the schedule is limited, an upgrade or award opening on a Bangkok flight rarely lasts. 2LNR checks every UTH 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.
