What's the best Android app for tracking someone's flight and knowing exactly when they'll arrive at the airport?

FlightAware Flight Tracker is specifically designed for tracking flights in real-time and monitoring arrival schedules. The app pulls data from multiple sources including FAA radar, ADS-B, and airline feeds to provide accurate position updates and estimated arrival times. For someone picking up a traveler, the app shows exactly where the aircraft is en route, current speed and altitude, and predicts landing time within minutes. Users can set up alerts for specific flight status changes like 'departed' or 'landed' that push directly to their phone. The airport overview maps display which terminal and gate the flight will use, eliminating confusion about pickup locations. While the free version covers most needs, some advanced features require a subscription. Reviews indicate the app occasionally experiences brief delays in updating flight status during rapid weather changes or airport congestion. The interface can feel slightly cluttered during initial use, but becomes intuitive after a few sessions. For reliable arrival tracking and pickup coordination, FlightAware delivers comprehensive flight monitoring capabilities.
