I don't think people should get the impression that 2-3 years to a command is the norm at Virgin. It''s the situation right now but it might not be the case in another 12 months time.
6 E170's going and only 3 E190's coming, new 737's to replace older aircraft. Crew slowly moving to the 4 A330 due over the next couple of years. More A330's expected but who knows how many or when (or even which pilot group will be flying them if they go international - probably PB not
VB).
A fair bit of movement with command upgrades this year but it will probably be much slower (read normal) from 2012 and onwards.
Still, it's a great place to work, just don't join with unrealistic ideas of time to command.
