I was just deciding bet. DL & AA.I went DL since I fly intl alot they have a better prog. for getting free ups even if M is the lowest fare many times its not that much more and this way you dont use up your miles for thatI've heard great things about CO, but I dont care for their award levels I'd need 80,000 to up a disc. tkt. or 80,000 for a free off-peak coach to where I fly to.DL cant help me to europe but from Europe to NY & on to LAX its 40,000 so I guess coach here I come BUT my suggestion is work out to where you will be flying & on a piece of paper list what is good and bad about each airline and then decide that's what I did .Actually, had AA not dropped their BOS to LGW then I would have gone AA too many bonuses to have pasted up,I feel that I'll be going to AA in 2001.
