No, worse. Plenty of threads on this issue elsewhere, which state that the FR take home after maximising own pension contributions averages at about £6k.
Nobody on here seems to know what a Jet2 Captain takes home.
5.6k - 6k after tax and pension contributions, depending on how many hours you are flying.
Biggest selling point is home base and the roster. 2 sector days at decent report times and only 500-ish hours per year, unless you are on the 757 then you'll struggle to make 3-400.
Of course the type / amount of flying can change in future. But at the moment it's quite a nice little number.
