You can use Chase Ultimate Rewards points to fly on virtually any airline, but the method varies. If you book through the Chase Travel℠ portal, you can use points like cash to pay for flights on almost any carrier, including low-cost airlines. However, for maximum value, you can transfer points at a 1:1 ratio to Chase's 10 specific airline partners: Aer Lingus, Air Canada (Aeroplan), Air France-KLM (Flying Blue), British Airways, Iberia, JetBlue, Singapore Airlines, Southwest, United, and Virgin Atlantic. Because these partners are members of the three major alliances (Star Alliance, SkyTeam, and Oneworld), you can use transferred points to book "award seats" on their partner airlines as well. For example, transferring to United allows you to book on Lufthansa or ANA, effectively giving you access to nearly every major global airline through the partner network.
