Hmmm... I'm not so sure it's just the roster Johnny. It depends on base and whether you are on a permanent UK contract at FR. I have a close friend that is a Captain on the 737 at Jet2. We had a discussion about this and I earned more last year than he did as a UK based FR 737 Captain. He works less overall however. So if you are talking about take home pay on a UK permanent FR contract then Jet2 doesn't win on all counts according to our recent comparisons. There is also scope for the right people with the required competencies and ability to earn more at FR by joining the training department in positions such as LTC and TRI/TRE. This is purely based on the fact that the airline is expanding to over 500 aircraft over the next number of years. However with all that said I know quite a few ex colleagues in both seats at Jet2 and by and large they are happy. I'm not knocking it by any means.
Safe Flying.
