Chiang Mai International Airport (CNX, ICAO VTCC) is in Chiang Mai, Thailand. It is the based hub of Thai Airways, Thai AirAsia and Thai Smile. In the SiamFlights catalogue, CNX is served by 15 airlines across 11 routes (10 outbound, 1 inbound).

Airport at a glance

Our catalogue records 10 outbound and 1 inbound corridors at Chiang Mai International Airport (CNX / ICAO VTCC), serving Chiang Mai, Thailand, across 15 carriers with 3 of them based here. Time zone Asia/Bangkok. Frequency across the corridors touching this field totals about 324 departures a week.

Coordinates are for checking, not decoration. CNX sits at 18.7668, 98.9626. That is genuinely useful when booking a room or a transfer, because “near the airport” is claimed to wildly different standards. In a large city, map distance and real travel time in peak hours diverge sharply — read the travel time for the hour you will actually move, not the kilometre figure.

IATA and ICAO are used in different places. The three-letter CNX is the IATA code that appears on tickets, bag tags and search screens; VTCC is the four-letter ICAO code used in flight plans, notices to airmen and operational paperwork. IATA codes can collide for historical reasons; ICAO codes do not, and their first letters encode the region. A four-letter code in aviation documentation is not an error — it is a different system.

Airlines serving CNX

Carriers we hold no row for. Jetstar Asia, Zipair and Thai Smile appear at this airport in our catalogue but have no alliance or baggage record in our database, so we print a dash instead of guessing. Check those carriers’ own pages before buying — an empty cell is more honest than an unsourced number.

Outbound

Inbound

Outbound and inbound are asymmetric because this is a catalogue boundary. We record 10 outbound and 1 inbound corridors for CNX. The gap reflects which route guides we chose to build — weighted to what travellers from Thailand search — not one-way service. The return flights exist whether or not we have published a page for them yet.

Corridors & fares from CNX

The 11 corridors at CNX break down as 9 short-haul (<4h), 2 medium-haul (4–7h), serving mainly ASEAN & regional leisure. We hold a cached fare for 10 of 11 routes, the lowest ฿1,179 on CNX–DMK. 15 carriers appear at CNX, 3 of them based at the field.

Most CNX corridors here serve ASEAN & regional leisure travellers. The mix is 9 short hops (under 4 h), 2 medium sectors (4–7 h). Fares are shown in Thai baht (THB), and each route guide below carries live cached prices.

Why some rows have no price. We capture lows in passes, and not every corridor returns a value each time. Seasonal routes, thin routes and routes sold through narrow channels report irregularly. An empty cell means no capture succeeded in the latest pass — not that the route is closed or expensive. We leave it blank rather than interpolate, because plausible-looking estimates are exactly what makes a table untrustworthy.

Everything is shown in baht, and that matters more than it looks. Fares are converted to THB so they compare on one page, but the underlying prices are set in the currency of the market that issues the ticket. The same corridor can price differently issued in different countries, and the exchange rate moves between our capture passes. Read these as a ranking, not as accounting figures.

How to read this list usefully. The frequency figure describes the risk in your plan, not the quality of the route: several departures a day gives you options when something breaks, a few a week means building in a spare day. We hold a cached fare on 9 of the 10 corridors here; the rest have no successful capture yet, which does not mean they cost more.

Direct flights to CNX — 1 route

Our catalogue records 1 inbound corridors into CNX from 1 country, block times 1.2 to 1.2 hours. Frequency figures are estimates combining every carrier on the corridor. The corridors touching this field connect 9 countries in our catalogue. Block times on those corridors run from 1.0 to 6.7 hours.

The destination country sets the rules, not the departure airport. The corridors here span 1 country, each with its own aviation regulator, visa regime and transit conditions. What you are owed changes with the destination and the direction of travel, not with the airport you left from. The route guides carry the detail per corridor.

The frequency figure describes the risk in your plan, not the quality of the route: several departures a day gives you options when something breaks, a few a week means building in a spare day.

Time zone and connecting at CNX

Our catalogue records 10 outbound and 1 inbound corridors here. CNX runs on Asia/Bangkok, the same as Bangkok. The gap is constant year-round. Every time printed on a boarding pass is local to that airport rather than an elapsed duration, so subtracting one from the other gives you the wrong number.

Minimum connection time is not in our data. Every airport publishes one, and the figure differs for domestic-to-domestic, international-to-international and terminal-change connections. A booking system will not sell you less than that on a single ticket — but it will happily let you build less than that yourself across two tickets. That is where passengers most often create risk without realising it.

International-to-domestic is a full re-entry. At most airports that connection means clearing immigration, reclaiming the bag for customs, then checking in and passing security again — even on a single ticket. It takes materially longer than an international-to-international transfer. Plan around the actual steps rather than the gap printed on the itinerary.
