After May 2009, SATA adopted a new brand image and a new logo which was applied to its first new Airbus A320-200, registered CS-TKO and named "Diáspora". The symbol, called BIA (for ""Blue Islands Açor""), consisted of nine geometrical shapes, representing the nine islands of the Azores assembled to form the mythical "Açor" of Portuguese legend. The ""açor"" or "northern goshawk" was thought to have been the bird found circling the islands of the Azores when Portuguese sailors first discovered the archipelago. This form appeared on the tail fin, in addition to a portion located just ahead of the wings on the fuselage. The new scheme was adopted by both SATA Internacional and SATA Air Açores during the fleet upgrades beginning at the end of the 1990s and lasted until 2015.
