Bangkok to Khon Kaen flight guide
Flying from Bangkok to Khon Kaen
In short
Khon Kaen is under an hour from Bangkok by air, and several airlines fly it nonstop. A few airlines leave from Suvarnabhumi (BKK); two leave from Don Mueang (DMK). The cities are about 378 km apart in a straight line and the flight takes around 55 minutes.
Khon Kaen is the commercial and university centre of Isan, home to Khon Kaen University and a growing conference trade, so weekday flights fill with business travellers and students as much as tourists. Thai Airways gives the route real depth from Suvarnabhumi, with 28 flights a week in its winter 2026/27 schedule. Thai AirAsia treats Khon Kaen as its North-East base, which is why it also flies from here to Chiang Mai and Phuket.
Picking the right Bangkok airport for Khon Kaen
If you are flying in from abroad, Suvarnabhumi is the obvious choice: a Thai Airways or Thai VietJet Air connection keeps you in one airport. From inside Bangkok, compare the journey to each airport before comparing fares. Don Mueang is closer to the north of the city and has its own Red Line station, while Suvarnabhumi is linked to Phaya Thai by the Airport Rail Link. Our Suvarnabhumi guide and Don Mueang guide cover both.
Ban Pet terminal off Highway 12
The airport is in Ban Pet, about 8 km north-west of the city centre and just off Highway 12 towards Loei. Everything happens in one four-storey terminal, rebuilt so that it now feels roomy and is rarely crowded. Arrivals and the transport counters are on the lower floors. A city bus runs into town from about 07:30 to 22:30, taxis charge a flat fare for the 15 to 20 minute ride, and limousine and car hire desks sit in the arrivals hall. The airport closes at night, roughly from 22:00 to 06:00. More detail is in our Khon Kaen airport guide.
Cabin-bag fares for a short Khon Kaen trip
Thai AirAsia, Thai Lion Air and Thai VietJet Air price their lowest fares without checked baggage; Thai Airways includes a bag in economy. For a short business trip with cabin luggage, the low-cost fares are hard to beat. For a longer stay, add the bag at booking.
Cool Isan winters and the silk fair
November to February is cool and dry in Isan and the best time to visit. March to May is hot, and the rainy season runs from about June to October. Khon Kaen's silk fair around the turn of the year is a busy period for hotels.
Runway, owner and passenger numbers
The airport lies roughly 8 km west of the city centre and belongs to the Department of Airports. Its single runway is 3,050 m long, long enough for jets of any size on this route, and it handled around two million passengers in 2017.

Frequently Asked Questions (FAQs)
Getting there
Thai Airways International and Thai VietJet Air from Suvarnabhumi, and Thai AirAsia and Thai Lion Air from Don Mueang. All of them fly nonstop.
About 55 minutes for roughly 378 km. It is one of the shortest domestic hops out of Bangkok, so the time at the airports matters more than the flight.
For most people, yes. The drive or bus takes six to seven hours and the train six to eight, while flying takes about three hours door to door.
About 8 km north-west, 15 to 20 minutes by taxi. The airport sits just off Highway 12, the road towards Loei.
Yes. A city bus runs from about 07:30 to 22:30 and is the cheapest way into the centre. It suits travellers with light bags.
No. The aerodrome works roughly from 06:00 to 22:00, so you cannot wait in the terminal overnight.
Yes. Thai Airways International and Thai VietJet Air both fly to Khon Kaen from Suvarnabhumi. On one ticket your bag is checked through after you clear immigration in Bangkok.
