I am hoping someone can help me with this. I normally fly US, but sometimes fly UA as *Gold. When I purchased my last block of upgrades, I asked what happens if the upgrades expire - as I did not expect to be flying UA very much going forward. The agent told me that PURCHASED upgrades will be reissued with a new expiration date???? I called the service center and was told that they would be converted to miles automatically (which they were not). Has anyone else been told this when purchasing e-upgrades?
