Got a discount on a couple rooms at the crew hotel for me and the wife and my sister and her husband in a cool city for new years. While hanging at the bar with my brother in law and waiting for the girls to get ready, I ask about a crew discount. Bar keep says we get 20% off. Already impressed by the deal we got on the hotel, my brother in law looks at me and says "Jesus man! Why do you airline people just get to live your whole life 20% off!?" I didn't have a good answer.

It's not an especially good story but it is a long way of saying: best perk? 20% off everywhere!!!
