I just want to be able to fly out of Puerto Vallarta without having my water mugged from me at the gate. You can't buy water, you can't fill up empty bottles -- you are simply not allowed to bring water on the plane, and until that changes, I'm not flying to Mexico again. I can't go 2-3 hours with only a tiny cupfull of water, refilled only if the FA has time and the inclination to do so.
