Passenger airlines in the U.S. - Statistics & Facts
The United States has the world's second-largest air travel market, with more than 369 million passengers being transported in 2020. With all the passenger traffic, it is no surprise that the U.S. American passenger airlines are some of the world's largest, with United, Delta, and American Airlines being among the world's largest. Several factors explain the leading position of the U.S. market. First is the country's size in terms of geography, population, and economy. Combined with the lack of a high-speed passenger rail network, these three factors create a huge demand for domestic flights, with this often the only feasible option for long-distance trips. Second is the country's status as a hub for intercontinental travel. Not only do tourism and business travel create a high demand for intercontinental flights, but the U.S. is often a stopover destination for flights to other countries in the region.
Low-cost carriers emerged since deregulation and have fundamentally changed the airline industry by offering significantly cheaper fares than full-service carriers. This is mainly achieved through charging extra for services like checked baggage, food and beverages, and inflight entertainment. U.S. low-cost carrier Southwest is the world's largest, while JetBlue and Spirit Airlines are in the top ten. Other U.S. low-cost carriers include Allegiant and Frontier. Interestingly, several low-cost carriers consistently outscore the full-service carriers for customer satisfaction.
Finally, regional carriers are those with operating revenue of below 100 million U.S. dollars and provide services to communities too small to justify the presence of a mainline carrier. The regional segment differs in that while the overall U.S. air travel industry has been growing, the number of regional airlines and passengers transported has declined. High operating costs, low demand, and the effects of the pilot shortage are the factors generally provided to explain this decline.
Types of airlines
In 2021, 61 airlines in the United States were in operation, of which 18 are classified as major carriers with over one billion U.S. dollars in revenue. Broadly, the airlines in the U.S. can be divided into three main categories: full-service legacy carriers, low-cost carriers, and regional carriers. Legacy carriers are those airlines with established interstate routes at the time of the airline industry deregulation in 1978. In the decades since, the three giant legacy carriers - Delta, American, and United – have collectively merged with or acquired most carriers existing before deregulation. Alaska Airlines and Hawaiian Airlines are the only other legacy carriers operating. The legacy carriers presently account for over half of the domestic market.Low-cost carriers emerged since deregulation and have fundamentally changed the airline industry by offering significantly cheaper fares than full-service carriers.
