PB Air was launched by its parent company, P.B. Air Company Ltd. in 1990 for the exclusive service of Boonrawd Brewery, the biggest brewery in Thailand. Its founder, Boonrawd president, Piya Bhirom Bhakdi, originally used the airline solely for flights transporting the brewery’s staff.
By 1995, PB Air applied for and received its license to provide charter flights to domestic and international destinations from the Suvarnabhumi International Airport, flying passengers to Bangkok, Buriram, Lampang, Nakhon Phanom, Nan, Roi-Et, Sakon Nakhon, Mae Sot, and Mae Hong Son in Thailand, as well as Da Nang in Vietnam, and Seoul in South Korea.
PB Air has operated several aircraft for its private brewery use and commercial charter services, which included a Dornier 328, three Fokker F28s, a Boeing 767-300, and two Embraer ERJ 145 LRs. By 2009, the airline was flying on two ATR-72-500s which it leased for use from Bangkok Airways.
Due to huge losses sustained by the airline, it suspended its operations by November 2009, and closed for good by December of the same year.
