The old BA cadet scheme hasn't been around for a few years now. They are screaming for pilots with experience now. Got jet time or heavy prop time, come on down.
The "cadet" schemes have changed in the UK. Now they're more along the lines of QF's. Ie you the prospective pilot pay for it.
There's some variations on a theme eg CTC. They train you (in New Zealand) and place you with an airline. The airline is only beholden to the pilot for 6 months. They can them employ them or let them go. (nice deal with a rather large loan hanging over you courtesy of HSBC)
