If you decide to spend the cash on training you'll look back in 20 years from one of four scenarios:
a) Your left seat of a Ryanair 737, earning £45,000 and flying 1200 hours a year due to European Harmonisation. This is your 14th sector today!
b) Your left seat of an EasyJet A319, earning £45,000 and flying 1200 hours a year but with 3 days off a week. This your second JFK today!
c) Your right seat of a One (BA) World AirBo 349, earning £48,000 and flying 1200 hours a year but with 96 year old CSD's and 75year old Captains. It's also 3am in the morning and you're only half way between Aukland and Basingstoke Intl. (They gave up on LHR years ago)
or
d) Your seat in the garden, cold beer in hand, looking up at those who persevered with the proffesion. You're glad you tried it but you're also glad you got out 10 years ago while the going was good.
If you don't, you'll regret it and if you do, you'll wish you hadnt!
