Google Wallet on Android now supports Live Updates for flight tracking. After adding your boarding pass, you’ll see a real-time progress notification with flight status, airline and estimated arrival time – visible on the lockscreen and always-on display.
The feature activates shortly before takeoff and includes a progress bar for the journey. It builds on existing Wallet features like check-in reminders and quick QR code access. Live Updates will also expand to trains and other events, similar to Google Maps navigation updates.
