Las Vegas McCarran is a Southwest Hub and their fleet of B737s, and home to National Airlines, with a good showing of their B757s. In fact, McCarran is an exceptional place for both B737s and B757s, with planes from lots of carriers making appearances. DC10s from United, Northwest, Sun Country and Hawaiian, a B747 from Japan Airlines and a number of business jets all combine to make Las Vegas an interesting and attractive place. Lots of takeoffs and landings.
