Timely arrivals and departures are the hallmarks of our service. We take all necessary steps to ensure our flight schedules are maintained but not at the expense of your safety. Working closely with Thai Airways International (THAI), we operate a code share agreement for all of our flights on the Yangon-Bangkok-Yangon route. This means that all our flights will have two flight numbers, with the flight designator code ("8M" for MAI and "TG" for THAI) and flight number of the airline actually operating the flight shown on the ticket.
