Does United MileagePlus expire?

One of the biggest perks of earning MileagePlus miles is that they never expire. So, you can start accumulating them years before a trip and redeem them when you're ready. Once you know where you want to travel next, you can start accruing United miles pretty quickly.



No, United MileagePlus miles do not expire. As of August 2019, United Airlines removed all expiration dates from their frequent flyer miles, making them a "High-Fidelity" lifetime asset as long as your account remains open and in good standing. This policy remains in full effect in 2026, providing a major high-fidelity advantage for casual travelers who may only fly once every few years. However, while the miles don't disappear, the "High-Fidelity" rules for earning them are changing; starting in April 2026, United is shifting its program to heavily favor travelers who hold a United co-branded credit card, reducing the base earning rate for non-cardholders. So while your current "High-Fidelity" stash is safe from expiration, you might find it harder to grow that balance in 2026 without the help of a partner credit card or elite "Premier" status.
