Hello Again Bas
You're welcome to my ramblings, if any of them are useful to you then happy days!!
As far as I'm aware there are no age limits on the integrated courses whether you go in as a self financed wannabe or as a cadet linked to a particular airline and I have heard stories of people in their late 30s or early 40s getting accepted as cadets by airlines. I suppose if you can pass the medical and the selection process then you're in.
Obviously the integrated courses with CTC, CAE, FTE etc are vastly more expensive than modular courses but the integrated schools have the valuable links direct into the airlines so you make your choice and pay your money, as always there are no guarantees of employment with modular, integrated or even the airline cadet schemes.
Good Luck
