AIP referenceVTCC — Royal Thai AIP, AD 2.VTCC (CAAT eAIP Thailand)
Operating hoursH24 since 1 November 2023 (previously 06:00–24:00) — aerodrome administration, ATS, customs, immigration, fuelling and handling all operate round the clock per the current CAAT AIP (AD 2.3), which also states no night curfew (AD 2.20). A 2005 EIA condition caps night operations (22:00–07:00) at roughly 6% of daily flights (about 12 flights/night) — an environmental guideline, not a curfew.
TerminalsSingle combined international/domestic terminal complex (two connected buildings, ~31,300 sqm total) with 20 aircraft stands (6 with jet bridges, 14 remote); a ~24bn baht expansion is underway — new international terminal on the south side plus renovation of the existing terminal for domestic use — targeting ~20M pax/year capacity (up from a design capacity of ~8M) by around 2034.
Runways (1)
- 18/36 · 3,400 m / 11,155 ft · 45 m wide · Asphalt · ILS CAT I (RWY 36 only, LOC 109.9/GP 333.8, 3° glidepath, DME CH36X); RWY 18 has no precision approach. A single displaced threshold near the RWY 18 end sets declared distances at RWY 18 TORA/TODA/ASDA 3,400m with LDA 3,100m, and RWY 36 TORA/TODA/ASDA/LDA all 3,100m (current CAAT AIP AD 2.12).
Airport contact
Thailand's fourth-busiest airport and the main gateway to the north, already running well above its ~8M pax/year design capacity (9.5M+ in 2025) on a single 18/36 runway with ILS CAT I on RWY 36 only, H24 with no curfew (though a legacy EIA condition softly caps late-night flight volume). Base for Thai AirAsia, Bangkok Airways and Nok Air, with Thai Airways as a focus city; also served by Thai Lion Air and other carriers. AOT is expanding the existing terminal (target ~20M pax/year by ~2034) and has a longer-term plan for a second airport, Lanna International, near Lamphun.

Ground handling
Available · 4 providers
AOT Ground Aviation Services Co., Ltd. (AOTGA)
AOTGA is AOT's own ground-handling subsidiary, created to serve AOT-group airports; however direct review of aotga.com's services page did NOT list Chiang Mai (CNX) among served airports - it explicitly names Don Mueang (DMK), Phuket (HKT) and Suvarnabhumi (BKK) for its handling lines. CNX coverage is plausible given AOTGA's mandate but is not confirmed by the operator's own site, so the earlier "confirmed via services page" claim is corrected here.
