Something some folks fail to grasp, is that just because you have the licence, it does not entitle you to the job. Newcomers are particularly prone to this, but older folks too. - as the chap above says, hours are not all that count.
He says he has thousands of hour experience on turboprops and a jet, but not obviously the 737 which he makes reference to, so target your job hunting to the airlines who operate the types you are rated on.
Whilst I don't condone airlines forcing you to pay for your own type rating, you can't really expect the airline X to pay for yours when there are still people willing to pay it themselves. It's a strategy which might not earn them friends - but it'll save them the £20K outlay for each new pilot they take on which is what the beancounters are most interested in.
Also a negative approach, admitting your 'consigned to the scrap heap' is not going to help either. You're not going to write the most polished letter nor come across in an interview very well if you already have that outlook.
He supplied his name and address too -
daft so-n-so. I hope he realises now he can only apply to companies who's HR Depts don't have access to Flight.
