Hi Sebastian,
Alex and I both fly for Atlas. Alex will definitely have a lot more insight on the 74 since that’s what he flies. As for me, I’m on the 73 and have a different perspective since the 73 only does domestic flying and has a lot more time off.
I encourage you to read my post here. The first half is about Atlas in general and applies to all fleets. The company itself is great and I have no real complaints about working here! It definitely can be a destination airline depending and what you truly want out of being an airline pilot.
