However, BCal eventually arranged for two aircraft to be leased from BA and Aérospatiale respectively and to have them maintained by either BA or Air France. It became necessary to find additional work for BCal's envisaged two-strong Concorde fleet to increase the aircraft's utilisation, thus permitting a cost-effective operation. Therefore, BCal decided to use the second aircraft to launch a supersonic service between Gatwick and Atlanta, with a at either Gander or Halifax. It also considered using the aircraft to serve Houston and points on its South American network at a later stage.
