AAdvantage members can strategically leverage mileage upgrades, often involving a cash copay, after acquiring eligible economy or premium economy tickets. Complimentary upgrades to Flagship Business are a highlight for AAdvantage elite members, extending to Executive Platinum elites even on award tickets. Additionally, systemwide upgrades, accessible through the American Airlines Loyalty Point Rewards program or Million Miler status, offer a seamless transition to Flagship Business at no extra cost.
