The number of miles required and the corresponding co-pay amount will depend on the origin and destination cities, as well as the type of ticket purchased. If you purchase a higher booking class and request an upgrade using miles, the co-pay may be lower or may not apply.

Over the past several months our valued members have provided us feedback about the introduction of a co-pay for United Mileage Upgrade Awards. We took those views into consideration and have adjusted our policy to give our members greater flexibility:

• Tickets in B class (United Economy) will not require a co-pay if upgraded with miles.
• Tickets in Z class (discounted United Business) will be eligible to be upgraded with miles and a co-pay, effective January 12, 2010.
