It honestly will just depend on what airline you want to fly for.

Check out their hiring requirements and see what they're looking for.

There's "Minimum requirements" and there's "Preferred requirements". Look at both if you want to be competitive.

But honestly if/when you get the interview it's not going to matter much what's on your resume. It's going to matter how you interact with everyone around you and if they can see themselves flying a 4-day trip with you.
