About how long will it take to clear customs at Bangkok's Don Mueang Airport (DMK)? We will be arriving on a Thursday at 10:15 am in a few weeks using Thai AirAsia X Airbus 330. We already have Thai 60 days visa in our passports. Thanks.
No one can tell how long does it take depends how many flights arrived, morning is mostly the busiest time. In 2015 when we arriving in DMK i remember it takes 30-45 min on queueing
Allow one hour from the time the plane touches down until you leave the airport. Possibly a little quicker but you never can tell
Customs. Do you mean immigration formalities? Customs should be a breeze unless you have something to declare.

Immigration formalities shouldn't take too long. However too many planes arriving same time or some mechanical issue could throw a wrench in the works. I would plan on an hour and hope things work faster.
If you are only heading to a hotel in the city area some hotels may not let you use the room before noon check in time. If scheduling a connecting flight I would allow 3 hours to be safe. (Bangkok has 2 airports by the way if scheduling departures.)
