Trans World Airlines, commonly known as TWA, was a major American airline that operated from 1930 until 2001. It was headquartered in Kansas City, Missouri, and became known for its extensive domestic and international routes. TWA played a significant role in the development of commercial aviation and was one of the first airlines to offer jet service. In 2001, TWA was acquired by American Airlines, leading to the airline's eventual dissolution. At its peak, TWA was recognized for its iconic red and white logo and its contributions to air travel, including innovations in passenger service and safety.
