Help with upgrade strategy
 

Doing a multi-city trip.
I'm CO Plat and UA 1K.
I purchased it on CO.com to get double miles on my Chase One Pass plus card and used my CO Plat #.

I have 4 CO 2010 SWUs which I never used yet. No UA Swu's or CRs.

1. [*]
2. [*]

I still have til tomorrow 5pm or so to cancel. Basically I want best odds of getting First or Biz on the longer portions.

I have the 4 SWUs on CO but would probably have to use miles on UA and I think I can't use them on codeshare, but not sure how the complimentary upgrades work.

Thanks for the help!

I'll throw it out there - no int'l trips planned between now and EOY/Jan'12 or whenever they expire? SWUs are incredibly valuable for those.

I'd use your UA number on ORD-SFO on UA. 10am flight, not prime business time, bet you could get it complimentary. Codeshare shouldn't have any effect on UDU.

I have a bunch for work but I get to fly biz.
I have trip to Paris but used miles so SWU not relevant.

So 1K gets your better chance than CO Plat? Can I change it after my first leg just so I can still try to get the SWU on the first CO leg?

It might be worth calling to try and swap your mileage UG for the SWUs. Or , worst case, keep watching, and if you see the R space open up, cancel and re-UG with SWUs.

Yes, 1K better than CO Plat on UA. And yes, you can change it after the first flight. You have 6 days in-between which is perfect, as 1K window is 100 hours.

OK Thanks for the info. FYI the first leg I am waitlisted via CO SWU not miles.
