The only big issue with flydubai is that silly rule that is allowing the first officers to keep their seniority even after they've been upgraded as captains.
I've never heard such thing before, it doesn't exist in any other serious company...Common sense dictate that once you pass your command upgrade (that in Flydubai is quite easy) then you pass behind.....If they keep this rule for the future upgrades they will loose all their valuable and experienced captains because they will never have the chance to become senior, never until the upgraded fo's are in the company....
