greenslopes,
Virgin Blue bases their pilots in the 4 big cities of one single country and not in some small sh!thole in the middle of nowhere at the far end corner of Europe, pays them a decent salary including a pension and all those things you can only dream of at FR, gives them staff travel tickets say on Delta or Emirates for themselves +family and friends and not nothing at all like FR.....
Virgin Blue and Ryanair,2 completely different things buddy.
As far as non UK pilots working in FR I would guess at least 70%.
