U.S. airlines' domestic market share
The passenger air transportation market is a thriving industry, taking individuals to locations around the globe. Delta Air Lines was the largest airline in the world based on sales, reaching more than 40 billion U.S. dollars in sales revenue in 2015. Passenger airlines can face much scrutiny for their passenger satisfaction and comfort. A 2016 North American Airline Satisfaction Study by J.D. Power & Associates listed Alaska Airlines and Delta Air Lines as the best traditional carriers for satisfaction, while low-cost airline JetBlue Airways earned the top spot of low-cost carriers tested in the study.
United Airlines, Delta Air Lines, American Airlines and Southwest Airlines are the top ranked airlines based on 2016 domestic market share.

At 358 billion, American Airlines boasted the most passenger kilometers flown in 2015. Chicago-headquartered United Airlines is a subsidiary of United Continental Holdings. United has flights to 238 domestic destinations and 60 different countries, the George Bush Intercontinental Airport in Houston being its largest passenger hub with over 40 million passengers every year.
