What feature does American Airlines offer to help passengers track their flights?

The feature that allows passengers to track their flights is through real-time flight tracking via the mobile app. This service enables travelers to receive up-to-the-minute information about their flight status, including departures, arrivals, delays, and gate changes, directly on their smartphones. This enhances the convenience for passengers, as they can stay informed and make timely decisions regarding their travel plans without needing to rely solely on airport information displays or customer service.

Accessing flight information through a mobile app can also allow passengers to receive notifications and alerts which are often more immediate and personalized than other methods of communication, fostering a better travel experience.
