Norwegian seem to have started a self-sponsored (pay-to-fly) type rating scheme. You can find the application details
HERE.
From what I hear, you pay your own expenses to attend the interview, sim check is on some kind of generic flight training device and, because there is no full sim assessment, you will be assessed during training instead. i.e. you could be leaving one job and then getted chopped during sim or line training as you have no contract of employment until passing final line check.
During training you get €100 per day (only for days of training) and pay your own accommodation (not sure where training is based). Once finished line trng you get Junior F/O pay of €3300 basic (up to 1500hrs) and then €4000 as F/O.
Sounds like a risky move to me, if you already have a permanent contract (I'm staying put!)
Ohh yeah, the cost is around
€23,000 €
