What is the current experience like when entering Thailand through DMK Airport?

The report describes a traveler's experience entering Thailand through Don Mueang International Airport (DMK) on May 10, 2023. The airport was mostly empty, with a brief 5-minute wait at immigration, luggage retrieval also taking about 5 minutes, and a straightforward customs process. The traveler noted a midnight onward flight to Chiang Mai with no wait at the Air Asia desk or security, although their flight was delayed by one hour. The comments reflected nostalgia for busier times, acknowledgment of current low travel season, and validation of low traffic at Chiang Mai airport during late hours.
