Orbest Orizonia Airlines, S.A., formerly Iberworld Airlines, S.A., was an airline with its head office in the Edificio Orizionia Corporación in Palma de Mallorca, Spain. It operated regular and charter flights to destinations in Europe and the Caribbean, scheduled domestic services, and scheduled international services to Havana. In its 14-year history, Orbest Orizonia flew to four continents and operated routes to over 30 countries. Its main base was Palma de Mallorca Airport. Orbest Orizonia was the air division of the Orizonia Group, Spain's third largest tour operator.
In February 1999, the airline took delivery of their first wide-body aircraft – an Airbus A310 – 300 from Transavia. Later that year, it received its fifth A320 and placed an order for two more of the type. 1999 was Iberworld's first full year of flying and passenger figures rose to over one million, the growth being so considerable due to the gap in the market left by Viva Air (which stopped operations in March 1999). This airline closure allowed Iberworld to open new routes to the Caribbean. On 28 February 2013, it was announced publicly that the Spanish travel agency group Viajes Barceló would buy the airline Orbest along with another travel agent chain called Vibo. Orbest previously employed over 800 employees but with this new deal by the Barceló group, the intention was to employ even more people, just over 900 employees. The airline declared bankruptcy on 5 May 2013 and ceased all operations subsequently.
