United Airlines MileagePlus miles never expire as long as your account is open and in good standing.

Previously, United miles expired 18 months after account inactivity, so the current policy is a nice improvement.

Earning United Airlines Miles

There are many ways to earn United Airlines miles easily:

United Airlines Credit Cards

For most people, I recommend the United℠ Explorer Card or the United℠ Business Card, which each provides a lot of benefits on United for a reasonable annual fee. For more frequent travelers, the United Club℠ Infinite Card is excellent if you want United Club airport lounge access.

Other options include United Gateway℠ Card (no annual fee) and United Quest℠ Card ($250 annual fee).

Transfer Partners

United is a transfer partner of Chase Ultimate Rewards (1 to 1), Bilt Rewards (1 to 1), and Marriott Bonvoy (3 to 1, but 2 to 1 if you transfer in increments of 60,000 Marriott points).

Fly on United

Members earn 5x miles per dollar spent on United or United Express, and Premier elite status members earn extra miles: Silver (7x), Gold (8x), Platinum (9x), and 1K (11x).
