The majority of Captains in the UK are permanent. And those that are not more often than not chose not to be.
Every FO at my base that applied for a permanent contract before Christmas got one.
Permanent FO in UK base can expect a P60 of about 61k
Permanent training FO (SFI) £80k to £85k.
Captain between £119k to £125k
Training Captain about £137k
Thats the situation in the UK with those directly employed with the company.
