It true all airlines have some some negative feedback but not to the extent of QR. The 5 Star status awarded by Skytrax is meaningless (see the
UK Advertising Standards Authority adjudication on Skytrax ). This is a commercial business funded by advertising and airline membership. QR certainly have lots of money to spend. There is no transparency and it has been suggested that Airline of the Year and awards go the biggest contributors. Skytrax can is not regarded as independent and is very secretive . Ownership is not disclosed.
On employment relations front I get the distinct impression the regime is harsh and unforgiving. From reading these forums it looks like their is a culture of blame and fear. The accounts here show interference with personal freedoms, lack of compassion and an inclination to discard employees without much forethought.
