U.S. airlines' domestic market share

The passenger air transportation market is a thriving industry, taking individuals to locations around the globe. American Airlines was the second largest airline in the world based on sales, reaching 44.9 billion U.S. dollars in sales revenue in 2019. Passenger airlines can face much scrutiny for their passenger satisfaction and comfort. A 2019 North American Airline Satisfaction Study by J.D. Power & Associates listed low-cost airlines and JetBlue Airways as the best long-haul and short-haul carriers.
