Airlines are falling over themselves trying to keep engaged with passengers before and long after they sit in an aircraft seat - and British Airways is no exception.
After the launch of the Perfect Days Facebook application in August 2011, BA has pushed the service to its more logical place: the mobile phone.
The service, currently available just for the iPhone, allows users to create and share their own personalised travel guides, and automatically integrates with the existing Facebook service.
Users can upload pictures and a description, tag the location on a map and then submit to the wider database of so-called Perfect Days, so other users can get ideas for things to do in a location.
One rather nifty feature is a "Meet Me" tool, which allows users to send their position quickly via an SMS text message to other users if they are arranging to meet at a location.
The expansion of the Perfect Days tool to a mobile platform comes less than a year on from the closure of the MetroTwin social network service, originally launched by BA three years earlier to encourage users visiting New York City and Mumbai to create guides and content on a dedicated microsite.
Certainly if MetroTwin (another in-house social network which fell victim to the rapid rise of Facebook in the late-2000s) had gained traction, a mobile service along similar lines to Perfect Days would have been the likely outcome.
