Hey! I am crew fro QFCCUK and its a fantastic base, only small so your not just a number with huge opportunities for promotions and other rolls on the ground such as First Hosts, Recruitment, Training and Base Ops. Generally get much more then 3 days off after trips, I had an block of 11 days off on my last roster and currently on a block of 6 days off before my next trip. I could pick up extra trips though if I chose to.
There is a huge amount of flexibility for commuters as you are able to change your roster to effectively suit yourself i.e. pull trips forward, create back to backs etc...I commute from Manchester efficiently by train but a lot of crew commute from Europe, in particular Brussels, Paris and Madrid.
Good luck!
