Barcelona's first airfield, located at El Remolar, began operations in 1916. However, it did not have good expansion prospects, so a new airport at El Prat opened in 1918. The first plane was a Latécoère Salmson 300 which arrived from Toulouse with final destination Casablanca. The airport was used as headquarters of the Aeroclub of Catalonia and the base for the Spanish Navy's Zeppelin fleet. Scheduled commercial service began in 1927 with an Iberia service to Madrid Cuatro Vientos Airport. This was Iberia's first route. During the time of the Second Spanish Republic El Prat was one of the bases of LAPE "(Líneas Aéreas Postales Españolas)".
