Dried Ears,
I'd like to refer you to
this page and specifically the following from it:
If I reach the holding pool, how long will it take to be placed with a partner airline?
We wish we could tell you! Sometimes it can be a week, sometimes 6 months or even a year. It depends entirely on demand from the partner airlines.
Am I guaranteed an airline placement if I get through selection?
There are no guarantees but, since 1994 when the ATP Scheme started, all those who reached the holding pool of short listed pilots were placed with an airline. It is just the timing that is hard to predict.
It's there, quite clearly, in black and white. You're not guaranteed a job, as the FAQ answer says, but the 100% placement record speaks for itself. They even say it might take a year. As far as I can see, they're telling nothing but the truth here. What exactly do you want?
