Wow, a very thorough and good comparison with little sarcasm. Very rare for this forum. Nice post. I would add that FedEx does a whole lot more day flying than most people realize. I myself prefer the night flying. Cleared direct almost immediately after talking to the first Center frequencey. Fewer convective thunderstorms. Except for in Memphis, no hour taxi delays because of congestion, like I had in Newark on Wednesday afternoon. The day hub turns are too long, unless you live in Memphis and can go home.
Nowadays, with load factors up so high, the free travel benefits isn't worth as much as it used to be.
