Fortunately (or maybe unfortunately) they called at about 2:00 a.m., confirming our upgrades for next weekend.
Really, just how urgent is this news???

I will be gladly awoken at any hour to find out an upgrade cleared, especially long-haul such as SFO-NRT!
However, did UA the person call, or did EasyUpdate call? You can specify "privacy hours" within EasyUpdate so you're not disturbed.
