If SLF have to be there in plenty of time to get through security, then so should crew. [This is based on present conditions, I'm all in favour of reduced checks on ID wearers]
That is assuming all crew only do one leg per day.
Should airlines schedule 2-3 hrs between connecting flights for crew?
With 1.15-1.30 hrs to shut down ,go through customs/immigration,do flight planning for next leg, go through security, get A/C set up for next flight, time is not abundant. If we spend 30-40 minutes waiting to go through security, I can guarantee the next flight will not leave on time...
