Connection from vietnam

[12is12]

Has anyone flown from any viet airport to chiang mai via BKK or DMK ?

Is there direct transit when arriving, with imigration in chiang?

Or will I need to deal with imig and luggage in BKK/DMK ?

BKK - CM is domestic flight, while VN - BKK is international flight, so you 100% will have to walk via immigration, pick up luggage and then go via security in domestic terminal

Moses is not entirely correct.

If you are travelling through BKK or DMK and you have two separate bookings with different booking references, then you will need to pass through immigration and collect your bags at DMK and then check in again for the flight to CNX.

if you are travelling through BKK DMK and both flights are booked under the same booking references, your luggage will be checked through from Vietnam to CNX under the CIQ scheme.  On arrival at BKK or DMK you will need to follow the Transfer / CIQ signs to the transit hall where you will clear immigration and be given be a CIQ sticker to wear on your shirt.  You then proceed to the gate for the flight to CNX.  On arrival at CNX staff at the gate will identify you as an international passenger and direct you to the international baggage claim and you will then clear customs in CNX.

Therefore it is clearly preferable to book both flights as a single booking with one booking reference.

To ensure the flights are booked under a single reference, flights are best booked using the airlines own website or app and not a third party booking site which may book them as two separate flights.    Thai, Bangkok Airways and Vietjet via BKK booked on the airline’s own website or app will automatically book under a single reference with luggage to be checked through to CNX.  If using Air Asia via DMK, you need to check that the flights are marked with the FlyThru symbol when making the booking, if using Lion Air via DMK, check it has LionAir Connect symbol.
