ALV2500,
I don't think age is really a factor with BA/Virgin. If you have the required experience and fit into one of the companies molds ;-) then they will take you.
One problem facing us 'oldies' is the time to captaincy. Obviously with up to 20 years to LHS I will be pushing retirement age by then! However, after 15 years of decision making as captain behind me, I don't personally see that as a great problem. As I say, that's my personal opinion, there are those that absolutley have to have that LHS power

.
Have a look for both companies on PPJN.COM and you will see that the FO scale far outweighs the captaincy scale for most budget operators, so the money issue is not there.
There were three mid thirty pilots taken from the twelve in my interview. The others, not taken, ranged from early 20's to mid 40's. Read in to that what you will.
Hope that helps
