Okay, so I have a weird issue. Whenever I try to upgrade flights and click request upgrade on the My Itinearies page, I get a "system error" message. If I go in through the e-upgrades section and hit Request Upgrade, it pulls up the correct screen, but only gives me the option of upgrading using a confirmed instrument. Under each flight, where it would normally let me upgrade using 500s, it always says "500 mile upgrades can only be used to upgrade one travelling companion." Right, I know, but I'm trying to upgrade myself. This used to work fine, but went away at the same time the functionality to sponsor upgrades using 500s did. What the hell?
