FlyerTalk Forums - UA Miles + $ CoPay Upgrade (refunded if no Polaris segments are upgraded)

From MileagePlus Upgrade Awards in the T&Cs

Quote:

What is the refund policy for MileagePlus Upgrade Awards that do not clear the waitlist?If you request an upgrade using a MileagePlus Upgrade Award, and none of your travel segments are upgraded, then we will automatically redeposit your miles and co-pay. In most instances, a MileagePlus Upgrade Award will be considered used if any segment of your travel is upgraded. However, if your travel includes requested upgrades to United PolarisSM business class or United Polaris first class, and none of the international premium segments are upgraded, then your MileagePlus Upgrade Award will not be considered used, even if you are upgraded to United First® or United Business® on another segment. In these instances, we will fully redeposit your miles and co-pay. When applicable, these refunds will occur automatically seven to 10 days after travel.

The uncertainty on PS (previously considered BF) segments appears to have been address, as PS flights are not considered Polaris flights
