Oh, poor naive Beckles!
First of all: DL/UA NO WAY.
Secondly, the Delta points for United flights may work for free flights, but not upgrades on United, which is all *I* care about, anyway. And even if I did cave and get a free ticket, it'd be to the South Pacific (NOT the pacific northwest...) so couldn't use YOUR airline's points anyway.
Third, Ok, you're right about the higher increments get a better exchange rate, I'll give you that one.
Fourth: Everyone KNOWS that Delta's only purpose in life is to serve as a pass-throguh for REAL programs...
