Mastertech Airline (Udon Thani) is a new start-up planning to operate domestic regional flights in Thailand from the northwestern city of Udon Thani. It has acquired a Piper PA-31 Navajo and plans to initially serve Phitsanulok and Ubon Ratchathani with the 10-seat turboprop. It hopes to be able to eventually add larger turboprop aircraft for leisure oriented flights to Hua Hin and Utapao as well as international destinations.
