Oleo,
Plenty of guys have had to relocate to get their commands. I did it myself at a time when my youngest child was 12 months old entailing a 220 mile commute with really only one useful day off at home - but guess what, you could always turn down the course and stay in the rhs! Payrise with some pain or easier life with less money - your choice. The company will offer commands where they are required, they won't invent a vacancy just to suit you. I take your point about DECs though. I eventually returned to my base to find DECs there who 'couldn't accept any other base for personal reasons'. That's just the way it is at Easyjet. I've since left by the way - not particularly unhappy with Easyjet, just wanted to try something different.
10% is a minimum considering the cost of living in the UK - good luck to all.
