RRFan, why don't you read up on the subject before commenting
are a good asian airline, managed, serviced and crewed by a mixture of vietnamese, asian, aussie, SA
and other westerners (like most other asian carriers!)
They have mix of modern (777, A321) and tired (B767, A320) jets plus the ATR's.
My experience (four internal and international flights on the 767's, A320 and A321's) was of an airline learning it's craft and with a great future.
I would recommend flying them if you get a chance and at some point in the future look forward to boarding their proposed non-stop LHR
