Udon Thani to Bangkok flight guide
Flying from Udon Thani to Bangkok
In short
Udon Thani has nonstop flights to both Bangkok airports, which matters if you are coming back from Laos or heading on abroad. Various airlines fly to Don Mueang (DMK), and two fly to Suvarnabhumi (BKK). The flight covers about 451 km and lasts around an hour.
A good share of passengers on this route have just crossed the Friendship Bridge from Vientiane. If that is you, the timing is the hard part: allow for the border queue at Nong Khai and the hour's drive to the airport, and do not book the tightest connection. Thai Airways' winter 2026/27 timetable lists 21 Udon Thani flights a week to Suvarnabhumi, and the Don Mueang airlines spread their departures through the day.
Two terminals, food and the Coral Executive Lounge
Udon Thani International Airport is 3 to 4 km from the city centre, a 10 to 20 minute ride. There are two connected terminal buildings with coffee shops, a buffet restaurant on the first floor and the paid Coral Executive Lounge airside in Terminal 2. Thai VietJet Air's SkyConX product lets you check bags through to Tokyo, Osaka, Taipei and Da Nang via Suvarnabhumi. The airport closes at night, roughly 22:00 to 06:00. Our Udon Thani airport guide has the details.
Don Mueang for the city, Suvarnabhumi for long-haul
Don Mueang is closer to central and northern Bangkok, and domestic arrivals in Terminal 2 are a short walk from the Red Line. It is described in the Don Mueang airport guide. Suvarnabhumi is where most long-haul flights leave, and the Airport Rail Link reaches Phaya Thai in about 26 minutes; see the Suvarnabhumi airport guide. If you must switch from Don Mueang to Suvarnabhumi, the free shuttle from Terminal 1, Gate 6, takes passengers with a same-day ticket, but traffic can be slow.
Room for shopping from Laos and Udon's markets
The low-cost airlines usually sell a checked bag as an extra. Buy it with the ticket if you are carrying shopping from Laos or Udon's markets. Thai Airways includes a checked bag in economy.
Free shuttle from Gate 6 or minibus 555
The free shuttle between Don Mueang and Suvarnabhumi runs from 05:00 to midnight from Gate 6 on the first floor of Don Mueang's international terminal, and you need to show your onward ticket. Minibus 555 makes the trip from Suvarnabhumi's Public Transportation Center back to Don Mueang between 06:30 and 20:00 for up to 60 baht.
