Just had a look at the above wesite, and the starting salary is the same as Virgin
The basic salary is probably the same, but as you may know, its the allowances that really make the difference.
So for example, with BA shorthaul you end up with the following a year:
Basic: £10,213 pa
Allowances: approx £500 per month
So the approx total for a year: £16,213
You can also earn more than this with BA, depending on what flights you bid for. I don't think VS pay as much as this - and thats longhaul!
