Flights Bangkok → Ubon Ratchathani (BKK-UBP) — THB Fares, Airlines, Frequency

Bangkok to Ubon Ratchathani links the capital with one of the principal cities of the Isan region, in Thailand’s far northeast near the Mekong and the Lao border. The route runs largely on residents, students, business travellers and family movement between the northeast and the capital, with a smaller share of tourism. Around 28 flights a week keep it frequent.

Block time is just over an hour. As a route shaped by everyday travel rather than a tourism season, BKK-UBP demand is fairly even through the year, lifting mainly around the major Thai holidays when people return home to the northeast.

Airlines on this route

Three low-cost carriers serve BKK-UBP: Thai AirAsia, Thai Vietjet and Nok Air. All three price the base seat low and sell checked baggage, seat selection and meals as extras. On a short domestic flight, many travellers fly with cabin baggage only and keep the fare minimal; when comparing, the meaningful figure is the all-in THB price once you have added whatever you need to check.

THB fares

BKK-UBP fares are low and competitive, kept that way by the all-low-cost line-up and the short distance. The cheapest seats are the early-released fares — booking two to five weeks ahead usually lands a good THB price, and mid-week departures undercut weekends. Demand and fares lift around the major Thai holidays, when northeastern families travel home in large numbers.
