Travel perk: Annual travel credit. The Chase Sapphire Reserve^® offers a solid point earning rate and the potential to transfer points to your United account at a 1:1 ratio. This means you can use your miles for United flights if you want to, but you're not tied down to this option if you find a better deal.

Yes, both the Chase Sapphire Preferred® and Chase Sapphire Reserve® cards work exceptionally well with United Airlines because United is a 1:1 transfer partner of the Chase Ultimate Rewards program. This means you can transfer your Chase points directly into your United MileagePlus account in increments of 1,000 points, and they usually appear almost instantly. This is often considered one of the most valuable ways to use Chase points, especially for booking expensive last-minute flights or international business class "Saver" awards. Additionally, if you have the Sapphire Reserve, you can book United flights through the Chase Travel℠ portal at a value of 1.5 cents per point (1.25 cents for Preferred), which can sometimes be a better deal if cash prices are low. Because United is part of the Star Alliance, you can also use your transferred miles to book flights on partner airlines like Lufthansa, ANA, or Air Canada, making the Chase Sapphire cards a favorite for loyal United flyers who want more flexibility than a co-branded airline card offers.
