Answer: Pan American World Airways, commonly known as Pan Am
Pan American World Airways, commonly known as Pan Am, was the principal US international air carrier from the late 1920s until its collapse on December 4, 1991. Founded in 1927 as a scheduled air mail and passenger service operating between Florida (Key West, and later Miami) and Havana, Cuba, the airline became a major company credited with many innovations that shaped the international airline industry, including the widespread use of jet aircraft, jumbo jets, and computerized reservation systems. Identified by its blue globe logo (widely known as "the blue meatball") and the use of the word "Clipper" in aircraft names and call signs, the airline was a cultural icon of the 20th century and the unofficial flag carrier of the United States.
