We traveled to Hawaii using CR-1s, part of our trip did not clear but last leg did. Before boarding I requested the gate agent to please return our CR-1 and take 500 miles upgrades. I checked the account Today and CR-1 are still missing and no 500 miles upgrades taken out.

Has someone else experienced similar challenge? How do I get my CR-1's back and give UA 500 miles upgrades.

HELP!
