The vast majority of BA cabin crew have a clear preference for the 744 over the 777.
Some of this can be put down to facilities available for crew on board however for many years there has been reports of crew feeling unwell, dizzy, nauseaus etc whilst working on the 777.
Whilst travelling as a passenger my preference is always for the 747 and in particular the upper deck which I always think as akin to a private jet.
I wonder if Virgin cabin crew prefer 747 over A340?
