Bragging rights today for British Airways with the launch of the first app to offer mobile boarding to users of the new Windows Phone 7.
BA claims it is the only airline in the UK to include such a facility alongside receiving mobile boarding cards after checking in on the Windows device.
[Added: On the global stage, of course, Air New Zealand can stake a claim to being the first airline with similar functionality on Windows 7]
A first for BA and its apps (already has iPhone, Android and Blackberry versions) is the inclusion of airport terminal maps for the first time, making use of what it calls the "dynamic home screen" on the Windows mobile.
Other features include real-time departure and arrival information as well as gate alerts for passengers using London Heathrow Terminal 5.
Perhaps the only wrinkle in BA's wider mobile strategy is that to make use of the mobile boarding system passengers must become members of the airline's Executive Club (although it is free).
BA says the app will be available from the Windwos Phone marketplace service from June 1 2011.
