Following on from WillyPete and only considering the financial side of being a pilot; can I float an idea?
I would suggest that there would be a higher percentage of disillusioned pilots in the S/SE of England factoring in cost of living.
For example, a £100k/yr Captain would be a 'rich' man in some parts of the UK(and no not just the bad parts), as that is still very very BIG money in some parts.
There are new build 3 bed, detached houses, with a garage in a country village in my part of the world selling for £145K, good luck getting a similar deal for twice the price in say Gloucestershire. They are 25 mins drive from my local airport where RYR, J2, EZY and TCX are based.
Spelling it out, £100k/yr would easily pay for a house and family in some NICE parts of the world.
Not suggesting that relocating your entire life is/or should be an answer, just think I'm spotting a trend!
