Moxie Marlinspike's advice comes to mind:
"... whenever I get on an airplane and walk past first class, I inevitably go through a familiar mental process. First, I’m envious ... then, I register who is sitting in those seats. It’s usually almost all predominantly unhealthy looking ... men, who it is clear from a glance have spent literally hundreds of hours of their lives over the past year in these airplanes ... the bulk of the first class passengers resemble each other, just as there’s a reason prison guards tend to act the same. I know that by making choices designed to land me in the first class cabin, it would be difficult to avoid also inheriting the dreariness associated with its current occupants."
