Yes, the Chase Sapphire family of cards (Preferred and Reserve) maintains a direct partnership with United Airlines in 2026. This is one of the most valuable benefits of the Chase Ultimate Rewards program, as United is a 1:1 transfer partner. This means you can move your Chase points directly into your United MileagePlus account instantly, allowing you to book award flights across United's global network and its Star Alliance partners. As of early 2026, United has introduced new "dynamic" pricing for some award seats, but the ability to transfer points remains a cornerstone of the Sapphire cards. This partnership is particularly useful for travelers looking to bridge the gap for a premium cabin upgrade or to take advantage of United's "Excursionist Perk" on multi-city international itineraries.
