Flying from Bangkok to Udon Thani
In short
Udon Thani is about an hour's flight from Bangkok, with several airlines on the route. Various airlines fly from Don Mueang (DMK); two fly from Suvarnabhumi (BKK). The straight-line distance is about 451 km.
Plenty of passengers are not staying in Udon at all. The Friendship Bridge to Laos is about an hour away at Nong Khai, so this domestic flight is the usual way from Bangkok to Vientiane without paying an international fare. Others come for Udon itself: the Bronze Age site at Ban Chiang, the lotus lake at Kumphawapi in the cool season, and from 1 November 2026 to 14 March 2027 the Udon Thani International Horticultural Expo, which will make hotels and flights busier than usual. Thai Airways' winter 2026/27 schedule lists 21 Udon Thani flights a week from Suvarnabhumi.
Terminal 2 by the Red Line or Suvarnabhumi connections
Don Mueang domestic flights leave from Terminal 2, a short walk from the Red Line station. Suvarnabhumi suits international arrivals connecting on Thai Airways or Thai VietJet Air. See the Don Mueang guide and the Suvarnabhumi guide for transport to each airport.
Hotel minibus from a former US air base
Udon Thani International Airport is on the south-western edge of the city, only 3 to 4 km from the centre, in two connected terminal buildings on a former US air base. A shared airport minibus drops passengers at their hotels, and taxis and car hire desks are in arrivals. For Laos, a minibus counter sells seats to Nong Khai and the Thai side of the Friendship Bridge, about an hour's drive. The airport closes overnight, roughly 22:00 to 06:00. Our Udon Thani airport guide covers each option.
Low-cost bag fees if you continue to Laos
Four of the airlines are low-cost: their cheapest fares cover a cabin bag, and checked luggage is extra. Thai Airways includes a checked bag in economy. If you are heading on to Laos for a longer trip, price the bag before choosing.
Cool season and the red lotus lake bloom
November to February is cool and dry, and the red lotus lake blooms from about December to February. The hot season peaks in April, and rain falls mainly from June to October.
The 19:00 bus from Suvarnabhumi as an alternative
The flight saves most of a day. Suvarnabhumi's Public Transportation Center sends a long-distance bus to Udon Thani at 19:00 for 428 baht, and another to Nong Khai at the same hour for 464 baht. They suit travellers landing from abroad in the evening who prefer a night on the road to a hotel in Bangkok.
