When talking about TOP FO payscale it could only mean you go straight onto SFO pay, even as an FO, or you do have 100% salary from the beginning, and not 90% during the first 6 month. Neither of this I found on the homepage, so I guess paywise nothing has changed.
NonTRSS with full ATPL, pays SFO wages, 90% during first 6months.
Non TRSS with frozen ATPL, pats FO wages, 90% during first 6months.
5/3/5/4 for UK AOC only.
