If you’re an AAdvantage member, you can use miles to request an upgrade, either when booking or later, subject to availability. Elite members (Platinum and higher) can use systemwide upgrades for eligible flights. Paid upgrades are also available, which may be offered at a discount closer to departure or during check-in.
