Spanish Air Taxi Líneas Aéreas S.A. was founded on 6 October 1959 by ex-Iberia pilot Rodolfo Bay Wright and ex-Iberia flight attendant Marta Estades Sáez. The airline was based at Gran Canaria Airport in the Canary Islands, and began operations flying geologists and technicians who were searching for oil in the Sahara and Spanish West Africa. Initial destinations included El Farsia, Gaada, Itguy, Mardesiat, Tindouf, Dakhla, Lagouira and El Aaiún. In 1959 the fleet comprised three Airspeed Consuls, two Airspeed Oxfords, one Auster and a single Avro Anson. A Douglas DC-3 was added to the fleet in 1960.
