Despite São Tomé & Príncipe being “blacklisted” as a destination by ICAO (International Civil Aviation Organisation) as it does not comply with EU safety standards and regulations, two certified airlines registered in Portugal serve the destination: TAP, the Portuguese national carrier and STP Airways operated by the Portuguese company EuroAtlantic.
For INAC (Instituto Nacional de Aviação Civi) the mid to long term strategy in coordination with ENASA (Empresa Nacional de Aeroportos e Segurança Aérea) is to work towards lifting the restrictions from ICAO, but so far it has been a challenge that the government has not managed to overcome yet.
