Khon Kaen Airport

Updated 28th Aug 2026

Khon Kaen Airport (KKC) is operated by Thailand's Department of Airports, a government department, and not by Airports of Thailand. That decides where the airport's official information comes from. Its terminal was rebuilt between 2018 and 2023 and reopened substantially larger.

The terminal that opened in 2023

The rebuild that began in August 2018 is finished, and anything describing it as under way or still to come is out of date. A new passenger building of 28,000 square metres went up alongside the original terminal, which was itself enlarged, giving a combined 44,500 square metres. The car park went from five floors to seven.

Bangkok Post reported in February 2023 that the two buildings were about to be connected to each other. Thai news site MGR Online puts the full public opening, with the new and renovated halves working as one airport, at 1 April 2023. A formal opening ceremony for the new building followed on 18 December 2024, more than eighteen months after passengers were already using it.

The rebuilt airport is designed for 2,000 passengers an hour, or 5 million a year. Before the work it handled 1,000 an hour and roughly 2.88 million a year. MGR Online described the result as the largest terminal in the Northeast, and its design as drawing on local Isan material culture, with references to the khene, a regional wind instrument, and to silk-weaving patterns.

Where Khon Kaen Airport is, and how to contact it

The department gives the airport's postal address in Thai only, on its own contact page for the airport, so the parts of it that carry across are the house number, 68/24, and the postcode, 40000. The telephone numbers run from 043-468170 to 043-468175, and there is a fax on 043-468186.

Published distances from the airport into Khon Kaen disagree, ranging from about 5 to 8 kilometres, so treat any single figure as approximate until you are in the vehicle.

How busy Khon Kaen Airport is

Bangkok Post reported in February 2023 that the airport had handled about 1.4 million passengers on roughly 10,000 flights during 2022, both figures well up on the year before. In June 2026 the same paper put traffic at about 1.8 million passengers a year, against the capacity for 5 million that the rebuild delivered.

In the same June 2026 report, Jucktrit Siripanich, president of the Khon Kaen Chamber of Commerce, called the lack of flights a critical challenge for the city, while noting that international flight slots can be increased.

Which airlines fly to Khon Kaen Airport

Thai AirAsia flies to Khon Kaen from Don Mueang, and launched a Suvarnabhumi route on 1 February 2025. Thai Airways resumed its own Suvarnabhumi service from 1 January 2024. Thai Lion Air flies the route from Don Mueang, and Thai Vietjet Air lists Bangkok to Khon Kaen on its own site.

Thai Smile no longer exists. It was merged into Thai Airways, which took over its Airbus A320 aircraft and its routes, and the brand went from 1 January 2024. Any roster that still names Thai Smile at Khon Kaen is out of date.

Which Bangkok airport Khon Kaen flights use

Bangkok has two airports and Khon Kaen flights use both, so which one you want depends on the airline you booked. Thai AirAsia's position is moving: its Suvarnabhumi service to Khon Kaen is suspended and the flights are consolidated at Don Mueang, reported as lasting until 30 September 2026 with a resumption planned for 1 October 2026. The three-letter code on the booking is what counts, not the city name: DMK is Don Mueang.

Khon Kaen routes with schedules on this site

This site holds schedule pages for two routes out of Khon Kaen:

• Khon Kaen to Bangkok
• Khon Kaen to Chiang Mai

The return legs have pages of their own: Bangkok to Khon Kaen and Chiang Mai to Khon Kaen. The city at the other end of the drive is covered in the Khon Kaen destination guide.

Hiring a car at Khon Kaen Airport

Avis and Budget each list a counter at the airport on their own websites. Avis gives its hours as 08:00 to 20:00, seven days a week. Budget puts its counter in the arrival hall and opens 07:00 to 20:00, also seven days a week, with a complimentary pickup service.

Both firms list their counters as closing at 20:00, so book the car or fix your onward transport before you travel rather than on the day.

What is inside the terminal

The department gives Khon Kaen its own facilities section, and the category pages under it carry no list of shops, food outlets or lounges.

Facilities lists published elsewhere disagree with each other, including on whether there is a left-luggage counter at all, and at least one of them describes the building as it stood before the 2023 rebuild. Anything you read about the facilities is worth confirming when you arrive.
