The revamped Don Mueang International Airport Terminal 2 will offer "sleep box" accommodation for late-night domestic passengers, along with many more new services, when it officially opens Mar 8
While the latest installment will consist of 25 sleep boxes in total, only five will be put to use upon launching this week. Rental fees for the boxes, which more closely resemble small rooms than sleep pods, will be charged by the hour and depend on travelers’ period of stay.
The Airports of Thailand's (AOT) renovation of the 100-year old airport will also see construction of a new passenger terminal connecting to the future BTS Red Line, which will better link Don Mueang with Suvarnabhumi’s Airport Link. 
AOT will also soon commence work to modernize Don Mueang Terminal 1. 
Stay tuned for more.
