What does sapphire mean on American Airlines?

Oneworld Sapphire is the mid-tier of the Oneworld Alliance program. As a Oneworld Sapphire member, you’ll get priority check-in and standby. For standby privileges, you’d come ahead of any Oneworld Ruby members. You’ll also get priority boarding, though that benefit depends on the airline you’re flying. Mar 25, 2022
