MileagePlus, explained.
Every Nanvero guide and calculator for United MileagePlus, in one place.
The short version
United MileagePlus miles do not expire; United dropped its 18-month inactivity rule in August 2019 and has not reinstated it. A balance is safe from lapsing but not from devaluation, because United prices awards dynamically against the cash fare, so miles held for years tend to buy less than they once did.
