Planning a trip to Khon Kaen

Collectively, Thai Airways (www.thaiairways.com; tel. 02356-1111), Nok Air (www.nokair.com; tel. 1318), AirAsia (www.airasia.com; tel. 02515-9999) and Thai Regional Airlines (www.thairegionalairlines.com; tel. 02134-7152) offer more than a dozen flights per day from Bangkok’s airports, Suvarnabhumi Airport and Don Mueang International Airport. There are also four trains running daily from Bangkok, and bus services abound. However, with some advanced purchase, the short 45-minute flight can cost as much as the 7-plus-hour train, which is around 700B.
