I just upgraded Indy-Vegas on AW by calling CO One pass, as always they were very helpful and willing to give 110%. I did use miles vs. ELTC (for fear of it being sold out). The process did take at least 15 min due to CO putting me on hold then they called AW to confirm the upgrade. It did take longer because it was an E-ticket?? Other than that all went very well.

What ever you do don't try to purchase an upgrade on AW thinking you will pay the reduced upgrade fare like CO has always been, they will advise you to purchase one of their upgrade booklets containing 4 coupons good for 500 miles each at the sum of $140. What was supposed to cost $75 at the counter almost double due to the fact that the One Pass agent that did call AW to authorize the upgrade didn't make sure they noted in the computer the $$ amount.
