You’ll need between 10,000 and 40,000 points to book a free one-way economy flight through Ultimate Rewards Travel. You’ll need even more points to fly mixed class, premium economy, or business class. Keep in mind that the exact number of points you’ll need for a free flight depends on the destination, time of day, date of travel, demand, and other variable pricing factors. Also, you can redeem points for outsized value by transferring your Ultimate Rewards to one of Chase’s airline partners, but the average number of points you’ll need varies widely depending on the transfer rate and a specific airline’s rewards schedule.
