I see all of you discussing overseas flights as good mileage runs. I think you can fly east coast to west coast for much cheaper and more miles. I can get some crazy cheap deals roundtrip. flights are routed PDX-PHX-PHL-PVD-CLT-PHX-PDX on us airways that's about 6k miles total without sweating. The PHX-PHL segment is a red eye so generally speaking your out about 24 hours and the airplane is your office for the day.
