Question: Why is this movie called "Airport"? It is not really a sequel to the original Airport, as Patroni is the only character in both films. Further, the original Airport focused on airport operations. It gave us glimpses of various airport professionals and how they respond to challenges and controversies. That was its appeal. But beyond showing the mobile lounge at Dulles, and it doesn't even introduce us to the pilot, Airport 75 has nothing to do with any airport.
Answer: It's all about branding and marketing. The first Airport film was hugely successful, prompting a sequel. Reusing "Airport" in the title has built-in name recognition that people would immediately associate with the previous film, which helps sell tickets. The movie is part of what became a movie series (four in all) under the collective "Airport" name.
