I know a guy who bought 500h on 320.
he got 400h (small a/c) + 500 320= 900h total.
he finishes unemployed."apply when you have 2000h total"
this guy is good to pay 2 times 500h + 100h.
lost his money for nothing!!!
I'd be willing to wager that if he bought another 1000 hours on the 320 at the same place, so he had 2000 total, they'd tell him to come back when he has 3000 total.
Folks, they're making money having you pay to fly for them, why would they consider hiring you and paying you to fly for them?
And other companies look at you as a high paying passenger, and discount your hours.
