Thanks for the replies.

I"m leaving this weekend and I don't have any UA SWUs, just the 2010 CO Swu's.

Out of curiousity, had I booked the flight directly on LH's site, rather than booking it on CO's site and getitng the CO flight #, would I have been able to do *A miles upgrade?

I booked on CO.com for 2 reasons 1) to get more revenue as a CO flyer and 2) I have CO One Plus card and wanted to get double points.

Forgot 1 more question:

1. is there a way to "see" how full 1st is? e.g. can you use the CO PDA site to see this flight?

(though if htere are no complimentary upgrades and I can't use an instrument not sure why I care! LOL)
