I understood that on an intake a few years back several pilots at Eastern were on a loan arrangement, in that the company took loans out in the pilots name to cover the type rating and line training; providing you stayed the company covered the loan for the 3 or 4 year duration, but in the event you leave well the loan is in your name so you are liable.
I wouldn't object to flying turboprops again, but when I work the figures through a sstr and line training package on a 737 or a 320 is actually financially more viable than spending fours years on a Jetstream Fos salary. I am not saying I support pay to fly schemes; but the awful terms at Eastern (and other turboprop oparetors) are actually something that has probably contributed to the popularity of pay to fly schemes.
