I'm sure others will be able to give you better insight as I never did any of it, but I don't think it's as bad as you hear.
The CS on one of my flights earlier this month was dating another crew for 2 years.
Just got permission for marriage, and they're also moving In together.
A lot of my FOs get busy with crew on layovers and stuff.
I think it's a few UNLUCKY guys that get it bad, and everyone keeps remembering those stories.
Wrap up okay.
