Timely thread...
I have a UA-coded, CO-operated B-class res that I have upgraded in advance as a UA elite.
On .bomb, the reservation is a mess, with some segments out of order and others gone completely.
On CO.com, I have duplicate segments, with one line item in B, and the other in ZE (upgraded business).
I don't really care about OLCI as I have the seat I want, but should I be worried about my upgrade in this situation?
