There really is no decision to be made. You cannot join Virgin. The pay is low, the morale is lower, the fun has gone and everybody is looking elsewhere. So what the jets are big? You never get to fly them much if you are Airbus and you are worked so hard that you don't want to get on them if you are Boeing.
Virgin is a marketing brand and not an airline, certainly not an airline that puts its employees anywhere near the top of the list of priorities.
Ask yourself why a company has to recruit so many crew, some 900 in the cabin and a significant amount on the flight deck, at a time of little expansion and depressed markets.
You will live to regret it if they throw everybody out again at the slightest risk of war.
Enjoy your command!
