Reader question: Flying from Bangkok to Chiang Mai, how does that work?

It depends a bit on how you booked, do you have everything in one booking? Then you don't have to worry anyway and the suitcases will be labeled to the final destination cnx anyway. If you have two bookings, it does not necessarily have to be a problem, but then you only know at check-in whether the bags will go through immediately.

In my opinion, it is advisable to also book the domestic flight at the same time, because in that case the carrier gives the guarantee to the final destination, if you are delayed in the meantime, the company is responsible for ensuring that you arrive at the final destination and are taken care of in the meantime. For example, I always fly with Emirates with the last flight from Düsseldorf to Dubai after a short stopover to Bangkok and there with the last flight of the day to Chiang Mai. If I am delayed in Dubai, Emirates is obliged to give me an overnight stay in Bangkok ( and transport) and the first possible onward flight to Chiang Mai, if you do not have ea in the same booking, that obligation lapses. But it has never happened to me and many major airlines including Etihad and Emirates have agreements with Bangkok Airways in this case so that they “hold up” the flight until all transit passengers have arrived.

If you can check in up to and including the final destination on departure and are therefore “tagged through” you will immediately receive all the necessary check-in cards, in the example above 3 pieces, which do not yet contain the gates, which you must check at the next departure airport. When you arrive at Bangkok follow the domestic airport signs (black sign with light letters), you will come to a post; thai Airways and Bangkok Airways where you have to show your check-in card, then you go through customs passport control (and possibly 30 days visa), hand luggage control and walk to the gate. If you smoke you must do so before the check-in card check because as far as I know there are no smoking louches on domestic. Upon arrival in cnx, only your suitcase will be checked, but usually they are already sleeping there, so that is nothing; piece of cake! In this way I skip Bangkok, so to speak, and I feel that it all goes much faster than having to go through customs in Bangkok.

I flew brussels/bangkok/chiangmai about 2 times in the last 8 years, arrived there in the morning
Please note, in the morning in chiangmai usually had a check of luggage, for everyone, by the way, during which the luggage has to go through the x-ray.
For example, you can bring 1 l of wine, they tolerate 2 bottles, but more or 3, they will certainly take out.
You don't get a fine, but you do get a sermon, and you have to hand over the too many bottles

This depends on the ticket, if you have both flights on a ticket, you can immediately indicate your final destination when checking in at Schiphol.
After landing in Bangkok, you can follow the instructions “Connection flight” and your suitcase will automatically go on the plane to Chiangmai, where you can also complete the Customs formality.
However, if you have 2 different tickets, where the "Connection fight" is carried out by another company, you must first receive the suitcase in Bangkok, then complete the Customs formality, and check in again with the 2nd ticket for the Connection flight to Chiangmai.
When booking 2 tickets, with different companies, I assume that you have calculated with a large interval, so that you can check in for your flight to Chiangmai without great stress.
