Before UA and CO merged officially on 03/03/12 I had 5 GPUs and 5 RPUs. Yesterday, I called the new UA reservation desk to sponsor two ONE-WAY upgrades using RPUs: (1) LGA-IAH-PDX (2) CLT-IAD-SFO-OGG Whereas sponsored upgrade (1) was applied without a hitch, sponsored upgrade (2) has been a huge headache. Yesterday, the agent failed to apply the RPU and asked me to call again tomorrow (i.e. today). I called earlier today and I was put on hold for over an hour before the agent came back to tell me that the CLT-IAD segment cannot be upgraded because it is a codeshare, although it is shown as operated by United Express. Since she said that the IAD-SFO-OGG segment was upgradable, I agreed to have the RPU applied, and I thought that was it. I then logged into my account to check my RPU inventory and was shocked to discover that I was not only down to 3 RPUs but also down to 3 GPUs (from 5)! Flabbergasted, I called UA again to find out why it took 2 GPUs and 1 RPU to upgrade a single itinerary (2). According to the agent, there has been a change in UG rules. It now requires a GPU to upgrade flights to Hawaii!!! Clearly, this was a mess due to the merger, where BusinessFirst flights were being confused for standard region 1 flights! I told the agent that the whole thing sounded ridiculous because the last time I checked, Hawaii was still part of Region 1, and there was nothing that indicated that a GPU was required for an upgrade to Hawaii !!! She then put me on hold yet again to check some more, and after another 60 min, with intermittent messages to let me know that the supervisor and IT were working on finding out what the problem may be, I was told that the whole upgrade system appears to have broken down and that I needed to call 1K desk tomorrow because they closed early today after being overwhelmed with similar UG problems. Has anyone out there experienced anything like this?
