Overview
Chiang Mai is northern Thailand's cultural capital, a relaxed city built around a moated, temple-filled Old City and ringed by forested mountains. It offers UK travellers a genuine contrast to the southern beaches: cooler air, superb food, hill-tribe markets and easy access to national parks. Interest in cheap flights to Chiang Mai rises every autumn as the cool season nears, so it pays to plan ahead.
Best time to fly to Chiang Mai
The cool, dry season from November to February brings the most pleasant weather and the biggest crowds, so book early for these months. March and April are very hot and overlap with the regional agricultural burning period, when air quality can fall noticeably. The green season from May to October is warm with short, heavy afternoon showers, but it is quieter and fares are usually gentler — check the When to book chart above. November also hosts the Yi Peng and Loi Krathong lantern festivals.
Airlines and routes
There are no direct flights from the UK to Chiang Mai, so every itinerary includes at least one change. A popular choice is a one-stop routing via Bangkok with Thai Airways, connecting to a domestic flight of around 80 minutes. Alternatively, a single connection through a Gulf or Asian hub works well with Qatar Airways via Doha, Emirates via Dubai, Etihad via Abu Dhabi, Singapore Airlines via Singapore or Turkish Airlines via Istanbul. London to Bangkok is roughly 11 to 12 hours non-stop; a realistic total journey time to Chiang Mai, including the connection, is about 15 to 18 hours.
Things to do in Chiang Mai
The city rewards slow exploration, with centuries-old temples, markets and mountain scenery all close by.
- Wat Phra That Doi Suthep: a gilded hilltop temple with sweeping views over the city.
- The Old City temples: Wat Phra Singh and Wat Chedi Luang sit within easy walking distance inside the moat.
- Sunday Walking Street: a large weekly craft and street-food market along Ratchadamnoen Road.
- Ethical elephant sanctuaries: observation-based projects in the hills where elephants are not ridden.
- Doi Inthanon National Park: Thailand's highest peak, with waterfalls, trails and twin royal pagodas.
At Chiang Mai International Airport (CNX)
CNX is only about 4 km south-west of the Old City, a 10 to 20 minute drive. You can take a licensed taxi from the airport desk in arrivals, book a car through the Grab app, arrange a hotel transfer, or share a songthaew (red pick-up truck). Transfers are inexpensive in pound terms.
Top tips for finding cheap flights to Chiang Mai
- Book roughly two to five months ahead for peak-season travel, and earlier still for December and the February festival period.
- Fly midweek and consider the green season (May to October) for the lowest fares and thinner crowds.
- Keep your dates flexible and use the price charts on this page to spot cheaper departure days.
- Compare a Bangkok connection on Thai Airways against one-stop Gulf and Asian carriers, as price and total travel time vary widely.
Travel essentials
British passport holders do not need a visa for tourism: Thailand currently allows UK visitors visa-exempt entry for stays of up to 60 days, with a passport valid for at least six months and proof of onward travel. The currency is the Thai baht, and you will usually get a better rate exchanging pounds locally or withdrawing cash on arrival. No vaccinations are required, though it is worth checking routine jabs with your GP and taking out travel insurance with medical cover. In March and April, sensitive travellers may want to monitor local air-quality reports.
