HAVE A SAFE FLIGHT

This is one of the dumbest catch phases ever invented. To say the words "have a safe flight" is to insinuate the possibility of a plane crash. The last fucking thing I want in my head right before getting on a plane is "have a safe flight! (Because there's a good chance that fucker will go down you asshole!)"

More appropriate terms to use just before someone travels….

"Good luck with the stewardesses!"

"Have a nice nap!" (The worst that can happen in this situation is one doesn't get any sleep. Much better than a plane crash).

"Join the half mile high club!" (Jerk off in the bathroom"

"I hope you don't sit next to a fat guy!"
