It was founded in 1927 as a scheduled airmail and passenger service operating between Key West, Florida, and Havana, Cuba. The airline is credited for many innovations that shaped the international airline industry, including the widespread use of jet aircraft, jumbo jets, and computerized reservation systems. It was also a founding member of the International Air Transport Association (IATA), the global airline industry association.

Wiki for TWA:

Trans World Airlines (TWA) was a major American airline which operated from 1930 until 2001. It was formed as Transcontinental & Western Air to operate a route from New York City to Los Angeles via St. Louis, Kansas City, and other stops, with Ford Trimotors.
