Log in to your Mileage Plus account at United.com using your username and password to start booking your intended flight with your available air miles.
Check the number of miles you have, and then compare it with the required number of miles for the ticket for your intended travel destination. Use the award chart found in the applicable link in your online account as a guide. Generally, Mileage Plus members can use their miles any time as no blackout dates are imposed on award travels in various destinations.
Decide how much miles you want to use for your intended award travel ticket. You can choose to pay for the entire trip with your available air miles or a combination of miles and money. To save on miles, you can set a priority for getting an United Saver/Star Alliance Award ticket. However, capacity control restrictions apply for this type of award. Since ticket allotment per flight is limited, booking a flight earlier is advantageous so you have a better chance of getting a ticket for your preferred flight destination and date. If no available United Saver/Star Alliance Award ticket is available for your preferred flight, you may get the Standard Award ticket as capacity control restrictions do not apply on this type of award.
Choose the flight you want and the number of miles you want to use in your account. Enter your credit card details in the space provided, in case you choose to use a combination of miles and money for your intended flight ticket. Click the confirmation button and wait for the confirmation-acknowledgment page to appear.
Print or save the confirmation-acknowledgment receipt in your computer for reference.
