Obviously "the unknown" you will soon be able to make up your own mind however my advice would be to ignore the bitter and twisted comments above. Whenever you get good news there is always somebody waiting to try and spoilt it for you.
I've worked for Virgin for five years and if it was half as bad as "padder" is saying then I would have left a long time ago. Morale is lower than usual at the moment because there was no pay rise this year.
I don't live with daddy and I've got a mortgage as have many of my colleagues. I certainly do not spend all of my time downroute in my hotel room watching every penny of my allowances. I have had many fantastic trips with genuine people and have established some great friendships.
I've used my staff travel on many occasions and have always been upgraded to Premium Economy or Upper Class when there is space available. The crew cannot possibly treat you any differently as a staff passenger because the revenue passengers would notice.
There is not a backstabbing environment. As you will find in every company there are a small minority who are self centred. Let's face it not everybody gets on with everybody however "false and fake gossips" are very few and far between.
My Crew Line Manager has been very helpful and supportive.
"Padder" if you are really as unhappy with the job as you sound then LEAVE. It's as simple as that.
