Not sure how many more times I have to say it...the benefit of route 3 over white tail is the 'opportunity' to get an easyJet offer at the end of ground school. Whitetail cadets can't do that and will complete all training before they get near an airline.
The big question is whether route 3 cadets are:
a) essentially "selected pending ground school"
b) the post- ground school selection is a clean slate
Option a) is a slight benefit over the standard whitetail route although it is still a risky propostion. Option b) makes little or no difference IMO. The majority of CTC cadets who do well in ground school will get a job with Easyjet or A.N. other. The risks (ie, not doing so well, global financial meltdown) are identical.
