As of September 2015, the British Airways app has instant access to upcoming flights. It allows users to do things such as book flights, check in and choose seats, download mobile boarding passes and get gate notifications and lounge Wi-Fi passwords.
While all of those actions are available to unregistered users, Executive Club members have added benefits. They are also able to track Avios and Tier points, view digital membership cards and book reward flights with Avios. The app is free to all users.
Using an Apple watch, users also have access to flight number and route, departure time with a countdown, on-time status and the weather at the flight destination.
