is it possible to fly to khon kaen from Suvarnabhumi? if so which airline is the best and cheapest to use any info cost websites would be appriciated thanks

Thai Airways and One-Two-Go fly between Suvarnabhumi and Khon Kaen

Thai Air

One-Two-Go

I normally use THAI but they are the most expensive for domestic flights. One-Two-Go I believe is much cheaper being they're a low cost airline, but I've never used them, only heard a couple of reports on them which were kinda negative.

I know that you asked about airline service, but there is also a bus that is scheduled to leave directly from the transportation center to Khonkaen.

According to the schedule I have, the Khonkaen bus is 311 baht and the ride is 6.7 hours.

I've used long distance busses in Thailand, usually part way through the trip the bus will stop for a (small) free meal, sometimes you get free snacks and water on the bus. Compared to Europe and the U.S. even without any food or snacks, these bus rides are a good deal.
