To redeem United Airlines miles, customers must log in to a MileagePlus program account to make purchases or reservations and select to pay with miles. Air mileage points earned through the MileagePlus program are redeemable for travel and purchases through United.com and partner websites. Miles can be redeemed for air travel, seat upgrades, hotel stays, cruise tickets and car rentals. Miles are also used to purchase magazine subscriptions, gift cards, concert and theater tickets and gifts from participating merchants.
The cost of travel or reservations made in miles may depend on availability and how much time there is between booking and departure. MileagePlus credit card members receive exclusive miles redemption opportunities. Members may purchase additional miles if there aren't enough available miles for the desired purchase. The Awards Accelerator program lets members purchase additional miles with each trip booked to help earn rewards at a faster rate.
Members are given the option of transferring miles to another MileagePlus member or donating them to charity in lieu of redeeming them. Members can choose from a list of charitable organizations to donate their airline miles to. Miles also can be used to bid on exclusive experiences, such as celebrity events and VIP tickets.
