Extended availability is a feature of Pro accounts that allows you to view availability for the entire calendar, instead of just 60-90 days from now. Extended availability doesn't update as often, but is a powerful tool for finding harder to book flight awards.

As of July 22nd 2023, all routes now support extended availability and allow you to view the entire calendar. However, shorter routes only support a more limited form of extended availability that can only be found on the Search page.

The icon on the Routes page indicates if a route supports faster extended availability that is visible in both the Explore page and Search page (bright green), or if it supports a slower version of extended availability that is only visible on the Search page (dark green).
