The cheek with the CTC ATP scheme is that these days they make you cough up £6,000 for their 'AQC' course without having a guarantee of a place on the ATP scheme: they make the AQC course the final stage of their selection. So it's a bit of a cash cow for them.
They are also rather circumspect about just how many people are swimming in their pool.
Having said that, low hours people have been regularly placed with major UK airlines through the scheme, in fact, ATP people were just about the only non-type-rated pilots that have been hired by UK airlines over the last 12 months.
So you could end up with another expensive piece of paper. Or you could end up with a very good airline job.
Like all things in aviation it's a costly gamble.
