If you request an upgrade using a MileagePlus Upgrade Award, and none of your travel segments are upgraded, 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 BusinessFirst® and/or United Global First™, and none of the United BusinessFirst or United Global First 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.
