What is a common feature in American Airlines' AAdvantage loyalty program?

In the context of American Airlines' AAdvantage loyalty program, accruing miles for every flight taken is a fundamental feature that encourages customer loyalty. Members earn miles based on the distance flown, the fare class, and their elite status within the program. This system allows travelers to accumulate miles that can later be redeemed for various rewards such as free flights, upgrades, and other benefits.

This feature plays a crucial role in incentivizing frequent flyers to choose American Airlines for their travel needs, as the more they fly, the more miles they earn toward their future traveling experiences. While free companion tickets, exclusive access to third-party airlines, and immediate refunds on canceled flights may be attractive offerings, they do not represent the core strategy of the loyalty program, which primarily focuses on rewarding travelers for ongoing engagement through mileage accrual.
