Some travel agency say that flight between Yangoon and Sittwe aren't reliable and punctual.
Do you know the airline concerned with this problem, and the approximate frequency?
I found 2 Airline that do this trip : "Air Mandalay" and "KBZ Airline".
Did you know other airline?
"Air Mandalay" and "KBZ Airline" don't seem to be full booked, so we can easily buy a ticket the same day without problems?
