Air Sul (1991/1992), Francia

Antes de las low cost ... estaban las charter. El mercado europeo estaba fuertemente regulado y la forma de viajar barato era mediante estos vuelos (que, algunas veces, eran un regular "disfrazado" para esquivar la legislación)

Muchos trabajadores de países del sur de Europa, como Portugal, los utilizaban en verano para visitar a la familia, aparte de turistas de norte y centroeuropa que visitaban las playas del Mediterráneo y del Algarve...

A pesar de tenerlo todo para prosperar, la portuguesa Air Sul empezó a tener problemas financieros en 1991 y en 1992 se declaraba en quiebra.

Before low cost airlines there were ... charter flights. European air traffic was heavily regulated and often, the cheapest way to get accros the continent was on a charter airline. Sometimes, charter flights were a "disguised" scheduled operation to avoid regulation.

Not only regular tourists, seeking the sun and beaches in the Mediterranean or Algarve region were users of these airlines, also many expat workers from Southern European countries flew them in the summer to visit their families.

Air Sul was one of these airlines. It was based at the Portuguese Algarve region and it seemed it was deemed to success; It faced financial trouble in 1991 and declared bankruptcy in 1992.
