Airlines & baggage

Airlines on this route

Five carriers fly BKK-CNX: Thai Airways on the full-service side, with Thai AirAsia, Thai Vietjet, Nok Air and Thai Lion Air covering the low-cost end. Thai Airways fares include baggage; the low-cost carriers price the base seat low and sell baggage and extras separately. On a short domestic flight, comparing the all-in THB cost once add-ons are counted is the fair way to judge value.

Fare trends

BKK-CNX fares stay competitive thanks to the frequency, lifting around the cool-season high season in the north, the year-end holidays and festival periods. The cheapest seats are the low-cost carriers’ early-released fares — booking two to five weeks ahead usually lands a good price, and mid-week departures undercut weekends. The hot-season and rainy months are the quietest and cheapest.

Seasonality & best time to book

Bangkok–Chiang Mai fares move with demand. The cheapest windows fall outside school holidays, Songkran and New Year; book 4–8 weeks ahead for normal dates.

About Chiang Mai

Chiang Mai is the principal city of northern Thailand, set in a valley among forested hills — an old walled centre dense with temples, surrounded by a modern city and, beyond it, the mountains and hill country of the north. It has a distinct northern Thai character, a strong food and craft culture, and a cooler climate than the central plains. For travellers from Bangkok it is the standard northern destination and the gateway to the wider region, from Chiang Rai to the national parks.
