Overnight somewhere in the middle to at least get yourself out of a plane. Surely you can get the government to give you that.
But, you must remember, there are far more people who do trips like these in economy than those who ride up front and they turn out just fine. Not quite as rested, but they got to their destination just the same. It seems there are a lot of folks here who would rather not travel at all if it meant sitting with the unwashed masses.
