Sounds like nothing has changed then in the many years since I was there.
Was very much a Hanoi Old Boys flying club then and sounds as though it still is. Blame the foreigner for their own incompetence.
VNA must be getting murdered by the likes of Korean and Cathay on routes to the US, and the Middle East Airlines on routes to Europe. The Asian Low cost carriers sense easy meat and nibble away on their short haul. VNA's domestic monopoly with Government forced low priced tickets will not save them.
What they need is a Non-Vietnamese CEO , who has International experience and the Governments power to hire/fire ANYONE in the Airline.
Otherwise the huge amount of robbing/scamming/fraud/corruption going on at VNA will continue and they will just bleed into insignificance in the region.
Shame, as they could be strong if they got their act in order, and in the meantime, continue to be subsidized by some of the poorest people in Asia.
