Flights Chiang Mai → Phuket (CNX-HKT) — THB Fares, Airlines, Frequency

Chiang Mai to Phuket connects northern Thailand directly with the Andaman coast, with around 14 flights a week.

Block time is about two hours.

Airlines on this route

Three low-cost carriers fly CNX-HKT: Thai AirAsia, AirAsia and Scoot. All operate the route on a budget model with a lean base fare and baggage, seats and food priced separately. The direct service is the main appeal — without it, the journey usually means a connection through Bangkok and several extra hours.

THB fares

As a domestic and short-regional route flown by low-cost carriers, CNX-HKT is reasonably priced, though the direct convenience means it sits above the busiest trunk routes. The Thai high season from November to February and the school holidays lift demand. Two to four weeks of lead time usually secures a low fare in THB, with mid-week flights cheapest.

About Phuket

Phuket is Thailand’s largest island and the main resort destination of the Andaman coast — known for its beaches, its old town with Sino-Portuguese shophouses, and its position as a gateway to the islands of Phang Nga Bay. For travellers from Chiang Mai it offers a complete contrast to the northern mountains, and the direct flight makes pairing the two regions easy.
