MileagePlus X

MileagePlus X is a mobile app that allows United Airlines frequent flyers to earn award miles and save money when shopping or dining. By using the app to make purchases at participating merchants or restaurants, you earn miles based on the amount spent. These miles can be redeemed for flights, upgrades, or other travel-related rewards. It offers a convenient way to accumulate miles outside of flights, turning everyday shopping into rewards, and helps travelers maximize their loyalty benefits efficiently.
