The BA World Cargo flights only operated through PIK because they were originating in Frankfurt and the rules in force at that time required a stop in the UK before proceeding to the USA. After realising that they were trucking cargo from PIK to STN they got consent to load here but of the three weekly flights only the Wednesday service ever seemed to have an uplift. The new "Open Skies" situation resulted in a review and since October they now fly direct from Frankfurt to the States.
