Airlines operate two types of flights: seasonal and year-round services. Seasonal flights target peak travel demand, while year-round services cater to consistent passenger flows. Legacy carriers have increasingly embraced seasonal routes following the COVID-19 pandemic.
United Airlines, a full-service carrier founded in 1931 and part of the Star Alliance, is among those expanding their seasonal offerings. United's CEO Scott Kirby oversees operations from multiple hubs across North America, including Chicago O'Hare International Airport and Los Angeles International Airport.
Seasonal flights differ from year-round services in that they operate only during specific high-demand periods. For example, summer sees increased flights from the U.S. to European destinations like Athens International Airport due to tourist demand. Winter routes often include flights from the Northeast U.S. to Florida or ski destinations such as Jackson Hole International Airport.
