How do I earn MileagePlus miles on partner airlines?

Earning MileagePlus miles on partner airlines is an excellent way to boost your mileage balance. MileagePlus has a robust network of airline partners, which includes both Star Alliance members and other airline alliances. When you fly with these partner airlines, you can earn MileagePlus miles based on the distance flown, fare class, and the airline's own mileage accrual rules. To earn miles with a partner airline, it is essential to ensure that you provide your MileagePlus number when booking your flight or during the check-in process. This number associates your flight activity with your MileagePlus account. Keep in mind that the number of miles awarded for a flight may differ from what you would earn on a United Airlines flight, as partner airlines have their own earning charts. Additionally, when flying with a partner airline, it is critical to know the eligibility of the flight for earning miles. Usually, full-fare tickets earn more miles than deeply discounted fares. It is advisable to review the airline's specific mileage earning policies, as they can vary. For the most accurate information regarding partners and mileage earning rates, United Airlines frequently updates the dedicated MileagePlus pages on their website. Visiting these pages can provide valuable insights into current participating airlines and their respective earning structures.
