I need to go to SFO on UA in October for work. I have 2 CR1s from a trade that are pending use.
I am Premier on UA (last year flying) PE on CO (status match).

Should I wait for space to open up as a CO PE (UDU) or is it possible to waitlist for a CR-1?
I tried looking at the UA sticky, but could not figure out a definite answer. Thanks

UA shows no upgrade space.

I can go with DL always, but the preferred carrier for this client (and the only nonstop) is UA.
