The Aviation Workforce: A Look at the Largest US Airlines

The airline industry is a crucial part of the global economy, and employment numbers can provide valuable insights into the success or struggles of a carrier. The largest US airlines by workforce size are not only a testament to their growth and adaptability but also a reflection of the industry's evolution over the years. American Airlines, for instance, has had a significant fluctuation in its workforce size over the decades. At its peak, the carrier employed over 100,000 staff members, but it dropped to around 63,000 during the economic downturn in the US. However, after the Federal Aviation Administration (FAA) awarded American Airlines and US Airways a single operating certificate, the workforce jumped to nearly 103,000 in the second half of 2015. This growth was largely due to the benefits of consolidation, including the partnership between labor unions and the discontinuation of the US Airways brand. United Airlines, another major player in the industry, has also experienced significant changes in its workforce size. The carrier employed close to 102,000 people in early 2001, but its numbers declined by about 20,000 following the terrorist attacks of September 11, 2001. United filed for bankruptcy in December 2002 and operated approximately 20% of all domestic flights. The airline's workforce steadily declined to about 46,000 toward the close of 2011 before merging with Continental Airlines and experiencing a significant increase in employment numbers.

Delta Air Lines, with its workforce of 100,000, has also undergone significant changes. The carrier reduced its part-time staff from about 2,000 to nearly 500 in 2022, a move likely correlated to schedule reductions. However, Delta's workforce increased to over 80,000 at the beginning of 2010 after merging with Northwest Airlines. Southwest Airlines, a low-cost carrier, comes in fourth on the list with 72,007 employees. The airline employed 70,590 full-time and 1,417 part-time staff. Its workforce increased from about 39,000 in the first quarter of 2012 to nearly 47,000 in April 2012, largely due to the acquisition of AirTran in 2011. JetBlue rounds out the list with 23,603 employees, 19,272 full-time and 4,331 part-time. JetBlue's story differs from that of the other operators on the list because it is comparably newer to the industry. The airline burst onto the scene under the name "NewAir" in 2000 with a staff of 450. Headquartered in New York, it entered service with East Coast routes.
