In 1918, by Decree No. 1889 of the State of Jalisco Congress, municipality title was granted to the town of Las Peñas as well as a new name: Puerto Vallarta; in memory of the illustrious lawyer and Governor of Jalisco, Don Ignacio L. Vallarta.
In November 11, 1954, Mexican airline “Mexicana de Aviación” opened its Guadalajara-Puerto Vallarta route. Back then, Aeromexico airline had enjoyed a monopoly on the route to Acapulco, but Mexicana found in Puerto Vallarta a beach destination to rival the famous bay in Guerrero. Visitors started coming from other Mexican cities and abroad. Among them were Guillermo Wulff, a well-known Mexico City engineer, and the famous film director John Huston, who wrote:
"When I came here the first time, almost thirty years ago, Vallarta was a fishing village of about 2,000 souls. There was only one-way to the outside world and was impassable during the rainy season. I arrived in a small plane, and first had to chase livestock on the outskirts of town to be able to land. "(Huston, 1980. An open book).
Enhanced by heavy advertising campaigns, Mexicana launched the Puerto Vallarta-Mazatlán-Los Angeles route in 1962. Through its affiliation with Pan American Airlines, this promotion was seen worldwide.
