Upgrading a UA ticket on US metal
If I buy a UA ticket to fly US metal and use the my US DM number to credit miles, can I still e-upgrade using my status window (SP), or am I stuck into standby at the gate (and if so, can I still use e-upgrades)? I don't see anything on the US site that references this situation.

A "Mileage Run"... is that what they're called? I've been doing them for years and didn't know they had a name.
