Just as an example,
I am UK based and have been since Line Training (aside from 2 weeks in MRS). A friend started at the same time as me, trained in LTN, was then BRS based and is now in NRN. He is 200 hrs better of than me which at the current rate is 14,100 euro over 18 months or 9,400 a year.
Its a trade of I guess with more money abroad or less at home. Then again I think all new guys are being based in the canaries or the other new bases.
good luck all
