Agency Being handles all Facebook activity for the BA campaign, and recently created the carrier's Facebook app that encourages people to "like" each other's holidays.
BA's upcoming campaign aims to use the heritage of the brand to rekindle pride among its staff and consumers, by addressing five decades of the carrier and its role within the history of aviation.
