They need to handle the tight connections the Frontier way. Everyone sit down and those who need off the a/c first raise your hands (just like third grade) to be identified for other passengers to give way upon exiting the plane. You miss a connection then it's a lesson in life not to book them so close, take it easy and enjoy the President's Club or something.
One thing I've learned to discipline myself in for sanity sake is that if you're ticketed coach, expect just that. Never expect an upgrade because when you don't get it, it will ruin your day. You only have a right to be upset about not receiving an F seat when you buy an F ticket.
