To upgrade on American Airlines, you can use several methods depending on your ticket and status. AAdvantage miles can be used for upgrades, either when booking or later, if available. Systemwide upgrades are available to elite members (Platinum Pro and higher) and can be applied to eligible flights. You can also opt for paid upgrades, which may be offered at a discounted rate closer to departure or during check-in. If you have a premium cabin ticket, you might be eligible for an upgrade based on availability. Upgrades can be requested via the American Airlines website, mobile app, or customer service.
