||Original, linen backed vintage travel poster: U.S. Virgin Islands Via Caribair. Caribair was an international airline that was based in San Juan, Puerto Rico. The air carrier served many islands in the Caribbean region as well as Miami, which was the airline's only destination on the U.S. mainland. Caribair was also the first Puerto Rican-based airline to operate jet aircraft on scheduled passenger services. The Caribair service was popular both with local residents and tourists alike traveling between Puerto Rico and other Caribbean islands. Caribair continued to expand during the 1950s and 1960s, and by 1962, the international airline was serving a number of destinations including San Juan, Santo Domingo in the Dominican Republic, Guadeloupe, St. Thomas, St. Croix and St. Maarten.
