Spantax was founded on October 6, 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 – Wiki

Spantax joined the jet-age in 1965 with two ex-American Airlines Convair Coronado 990’s. The Convair 990 was a narrow-body four-jet airliner produced by the Convair division of General Dynamics. Spantax later acquired 12 more CV990’s four of them from Swissair. Several more jets were acquired through the 70’s. A brand new DC-8 and also an ex-DC-8 from Trans Caribbean Airways. Their DC-9’s came from Southern Airways. In October 1978 the airline put into service its first wide-body aircraft, a McDonnell Douglas DC-10-30. No mention where their DC-10 came from. In the 80’s they leased a couple 737’s and a 747. They ceased operations in 1988.
