Flights Chiang Mai to Singapore (CNX-SIN): Airlines, THB Fares

Flights Chiang Mai → Singapore (CNX-SIN) — THB Fares, Airlines, Frequency

Chiang Mai to Singapore connects northern Thailand directly with the city-state, a route that lets travellers from the north reach Singapore without first routing through Bangkok. It carries tourists in both directions, students, business travellers and passengers connecting onward through Singapore. Around 14 flights a week keep it steady.

Block time is about 3 hours. The route is shaped by the northern Thai tourism season and Singapore’s holiday periods, and the all-low-cost line-up keeps fares keen.

Airlines on this route

Three low-cost carriers fly CNX-SIN: Thai AirAsia, Scoot and Jetstar Asia. All three price the base seat low and sell checked baggage, seat selection and meals as extras. On a three-hour route, many travellers still fly cabin-baggage-only; when comparing, count the baggage you need into the total, since the all-in THB cost rather than the headline fare decides value.

THB fares

CNX-SIN fares are competitive, held down by three low-cost carriers on the corridor. They lift around the northern cool-season high season, Singapore’s holiday periods and the year-end. The cheapest seats are the early-released fares — booking two to five weeks ahead usually lands a good THB price, and mid-week departures undercut weekends.
