The reality is no-one was ever guarenteed a position - condition 2 on the conditional offer letter clearly said it was dependent on there being places available.
If you left your job then you took a risk that didn't pay off - that wasn't QFLink's fault.
The unfortunate thing about aviation is there are too many negative people who feels the world owes them - lets just sum up the QFL traineeship to date:
1. They established a program that allows for recruitment of pilots well below any direct entry requirements of any airline in Australia,
2. They paid for airfares & accom for applicants to travel to the recruitment (which not many airlines do - including QF),
3. They made exceptionally quick conditional offers & didn't hold people after the recruitment days for months as other airlines (including big brother) does,
4. Once in they will refund an amount of ATPLs,
5. Once in they pay for bridging courses to get you up to scratch,
6. You are remunerated far better once in then others with the same experience elsewhere,
7. QFL didn't cancel the program but instead have at least enabled to keep it going.
As someone with a conditional offer I'm happy that the program is still in one piece and can't really see where they have ever been non-transparent with us?
I'd suggest that if you can't deal with a minor set back like this in your fast tracked career then as krusty said this may not be the right industry for you.
