Viva Air, whose complete name in Spanish was Vuelos Internacionales de Vacaciones (International Vacation Flights,) was founded on 24 February 1988 by Iberia and Lufthansa. Operations began with A320 aircraft. At the beginning flights were mostly from Germany to Spain, in particular to Palma de Mallorca. By 1992, the partnership between Lufthansa and Iberia dissolved and Iberia took over the operations of Viva Air. Shortly thereafter, Viva Air entered the Spanish domestic scheduled market using Douglas DC-9 aircraft but those were quickly replaced by the Boeing 737-300. 

The airline's aircraft stood out with their simple and colourful style livery created by Spanish school children. It was intended to symbolise the Spanish sunshine which most of its passengers sought during their holidays. After the first few years of operation, the airline was one of the first subsidiary airlines of a major carrier (in this case IBERIA) to gain a foothold into London's Heathrow Airport from where Viva Air operated several scheduled services on behalf of its parent company using Viva Air call signs and Viva Air flight numbers.

Since the scheduled flights were losing money, Iberia took over those routes and Viva Air was relegated to charter flights using Boeing 737-300 aircraft of which it had 10 in service by 1995. Owing to heavy competition from other Spanish and European charter companies, Viva Air began to lose money and, by 1999, operations ceased and the airline was liquidated. Iberia took over all staff, aircraft and route licenses as Viva Air ceased to exist and it’s name relegated to the history books.
