Understanding how free upgrades work can significantly improve your chances of enjoying a better seat without extra cost.

MileagePlus Elite Status Free Upgrades

MileagePlus Premier members are eligible for United Airlines free seat upgrades on select routes, primarily within the U.S. Complimentary upgrades are prioritized by elite tier, fare class, and booking time.
