THAI adds Siem Reap to its summer timetable

THAI will operate the Bangkok (BKK)—Siem Reap (SAI) route daily using a 164-seat A320 for the one-hour flight.

The start-up date is 1 October, just weeks ahead of the winter peak travel season and the airline’s winter timetable, which kicks in on 26 October.
