I'm sure you'll be suprised... but I agree with both of you! But everyone knows... the Cigar likes his CO.
If I were silver i'd be flying AA. And if I was flying mainly international, I'd get a lobotomy (so I wouldn't know I was flying UA) and fly UA.
P.S. I have a house in Los Angeles. I believe that would be west coast... Kinda kills the east coast only theory. I fly to all 50 states each year. Also I do fly some international (and burn miles GASP! for upgrades). But, I do understand the west coast CO problem. I'm forced to fly HP or AK to travel north/south on the west coast.
