I was looking at the AQC course at CTC based entirely on the fact that it seems to give a better opportunity of being placed with an airline post-training.
I have no evidence to actually back this up, and of course CTC would tell you this, but I know that you can do a CPL/ME/IR cheaper at the likes of Stapleford or BGS and certainly the MCC/JOC courses are cheaper than the AQC. However, as far as I can see the extra money invested in CTC is purely down to the (supposedly) better opportunity it provides post-training.
Happy to be corrected, of course, but as far as I can see it is the only reason they would cost more than elsewhere, given that I'm led to believe the standard at the likes of Stapleford and BGS is also very high.
