"Good move for Virgin - mixed fleet flying 340/330 will help costs, crewing and more choice of routes for the drivers"
That's a good point BRAKES HOT about the choice of routes (a nice side benefit). I am sure the current 400 drivers would probably appreciate some more variety (even though beach time in Antigua or Havana every week wouldn't be bad at all) and vice versa. I am sure Orlando gets a bit old after a few trips...
