That is quite a bold statement, especially considering how factually incorrect it is.
New hired SAS mainline pilots and upgrades on forced part time in winter, only variable roster and starting salary below 3500€ gross for new hires and 5500€ gross for new upgrades. Payscale is 24 steps before topping out below SAIL LHR captains pay. Payscale for FOs capped at 5500€ after 14 years. This was all before COVID-19.
Can you please elaborate on how this ”mainline salary cost” hurts our comptetetiveness?
