Questions about Bangkok to Khon Kaen

Which month is cheapest for Bangkok to Khon Kaen?
February is the cheapest of the next 5 months to travel from Bangkok to Khon Kaen, at €32.59 for one passenger. Each month is priced on its fifteenth, so the comparison is like for like rather than a mix of weekends and midweek departures.
Who runs service from Bangkok to Khon Kaen?
No operator record names Bangkok to Khon Kaen directly. Nok Air, Thai AirAsia, Thai Airways International, Thai Lion Air, Thai Vietjet Air publish service areas covering both ends and may serve it, so we list them as possible operators rather than confirmed ones.

Every service we sell from Bangkok to Khon Kaen is direct, with around 40 departures a day and a fastest journey of 4h 5m door to door. No connection is needed, so there is no missed connection risk to plan around on this corridor.
Which station or terminal do services from Bangkok to Khon Kaen use?
Services from Bangkok to Khon Kaen by flight leave from Bangkok BKK and arrive at Khon Kaen KKC. Allow about 3h 10m in total for reaching the departure terminal and leaving the arrival one, which is already included in every door to door time on this page.
Can I change or refund a ticket from Bangkok to Khon Kaen?
0 of the 5 operators we sell from Bangkok to Khon Kaen allow a change or a refund. A change on a changeable fare costs €5.00. The operator table on this page names which is which, and the condition is shown again before you pay.
Where these numbers come from
Places, coordinates, operators, which operator serves which pair, and every distance on this page are real and come from open data. Where a corridor has a filed timetable the departure times are real too, and ferry fares are the prices the operators publish themselves.
Derived from service area No carrier record names this exact pair. The operators listed publish a service area covering both places at a distance their mode plausibly carries people, which is evidence that the corridor is served and not evidence of a specific service. Pages state which, because presenting the two as the same thing would be dishonest.
Where no operator publishes a fare for a corridor, the price here is our own estimate, worked out from the real distance and the real operator through a fare curve that follows lead time, day of the week and season. It tells you roughly what the journey costs. It is not a seat anyone has agreed to sell, and the payment step will not take it.
