There is a statement in red at the bottom of each pprune web page:
"As these are........certain reactions".
To post one does not have to prove that one is who one wants to appear.
Perhaps this statement should be considered when reading the posts of some of the more outlandish posters who claim to be cabin crew, persons who do many £'s worth of business with BA etc..
Some posters may even work for another company and may benefit from BA's misfortune.
I certainly have my doubts about some.
