    The train timetable from Khon Kaen to Bangkok

    The journey times are taken from the Rail Thailand timetable of January 2026 and the copy of the SRT timetable from Travelfish of February 2026. Line 134 departs from Vientiane at 18:25 and line 26 from Nong Khai, so both may arrive late in Khon Kaen.

    The night train to Krung Thep Aphiwat

    The best way to use night trains in Isan

    Heading south, you can catch the night trains at convenient times. The Special Express No. 26 departs from Nong Khai, leaves Khon Kaen at 9:49 PM, and arrives in Bangkok around 5:30 AM. It offers first-class compartments as well as air-conditioned second-class sleeper cars. On 12Go, a second-class sleeper car costs approximately 1,197 baht in mid-November, and first class from around 1,684 baht. Thailandtrains lists fares at individual stations as 907 and 1,394 baht. The Rapid No. 134 departs from Vientiane, leaves Khon Kaen at 10:51 PM, and arrives in Bangkok at 7:30 AM – a more convenient arrival time. Inexpensive third-class and second-class seats are available.

    I would book train number 134 if I didn't need to be somewhere early, and number 26 if I wanted to arrive earlier and travel first class. Both stop at Don Mueang station, directly opposite the airport, at 5:15 a.m. and 7:15 a.m. – ideal for a late-morning domestic flight. Since train number 134 originates across the border, there can be delays upon arrival in Khon Kaen, so check the departure board at the station before you travel.

    During the day, express train No. 76 departs at 10:11 AM and arrives in Bangkok at 4:35 PM. A stopover in Ayutthaya is possible around 3:39 PM. According to SRT booking regulations, seats from Khon Kaen can be booked approximately 90 days in advance on the SRT website (D-ticket), at the train station, or via 12Go (for a fee).

    • Flight from Khon Kaen to Bangkok

    Select the airport based on your next travel destination.

    Khon Kaen Airport is located approximately 11 km northwest of the city center and can be reached by car in about 15 minutes. A 12Go flight overview for a weekday in mid-November showed seven departures to Suvarnabhumi Airport between 8:30 am and 8:15 pm with Thai Airways and Thai VietJet, and six flights to Don Mueang Airport between 7:35 am and 9:10 pm, primarily with Thai AirAsia and Thai Lion Air. Flight times were approximately one hour. Prices ranged from approximately 1,050 to 1,400 baht to Don Mueang and 1,235 to 2,075 baht to Suvarnabhumi.

    If you have a connecting flight abroad, try to fly to Suvarnabhumi Airport on a single ticket if possible. Don Mueang Airport is 60 to 90 minutes from Suvarnabhumi, and this is where tight connections can cause problems. If you're staying overnight in Bangkok, both airports are suitable, although Don Mueang is usually cheaper.

    Buses to Mo Chit

    Buses to Bangkok depart from Khon Kaen 3 bus station, located on the outer ring road, about 6 km from the city center. Most buses are operated by Nakhonchai Air. Gold-class buses depart from 6:30 am for approximately 443 baht (via 12Go), while some first-class buses cost around 591 baht. Chandchai Tour express buses cost approximately 380–550 baht. Late at night, Chan Tour offers express buses at 11:00 pm, 12:30 am, and 1:00 am, arriving in Mo Chit between approximately 5:40 am and 6:10 am. The journey takes about six to seven hours. Some Nakhonchai buses also stop in Ban Phai and Phon, south of the city.

    The buses terminate at Mo Chit in Chatuchak, from where you can reach the Mo Chit BTS station and the Chatuchak Park MRT station by taxi or in a few minutes. Nakhonchai Air also stops at its own bus terminal in Bangkok.

    By car

    The route via Highway 2 through Korat and Saraburi is approximately 440 km and takes about five and a half hours without traffic; in Bangkok's heavy traffic, it takes correspondingly longer. Rental cars with drivers from hotels in Khon Kaen to Bangkok are offered on 12Go from approximately 4,400 to 9,800 baht, depending on the vehicle type.
