People should not get route 3 mixed up with route 4.
Route 4 (at OAA) is simply whitetail, you must do an interview with easyJet at the end of it your training.
Route 3 is exactly as m585 explained ... you are an easyJet cadet.
My reservations are that I personally want the MPL and think the ATPL course is quite steep in price, but that is a personal thing for me.
