An Outlook at Key U.S. Airline Mergers

Updated: Mar 27

Strategic mergers have continuously reshaped the U.S. aviation industry, and since the early 2000s, major players have entered revolutionary unions. This is a thorough history of the eight mergers that shaped the airline business and made American Airlines, Delta Air Lines, Southwest Airlines, and United Airlines what they are today.

2001: American and TWA.

In a move to enhance competitiveness, American Airlines announced its acquisition of Trans World Airlines (TWA) for $500 million. The deal aimed to position American as the second-largest U.S. airline. However, the aftermath of the September 11 attacks led to restructuring, and TWA's integration saw changes to American's initial plans.


2005: America West and US Airways.

America West Airlines stepped up with a $1.5 billion deal to acquire bankrupt US Airways, marking the first significant merger of the modern era. Led by America West management, the newly formed airline adopted the US Airways name, paving the way for future consolidations.

2008: Delta and Northwest

In a groundbreaking mega-merger, Delta and Northwest joined forces, creating a market leader with a 20% share of domestic and international seats. The $2.8 billion deal reshaped the competitive landscape, solidifying Delta's position as a major player in the U.S. airline industry.

2009: Frontier and Midwest

Despite facing challenges, the merger of Frontier Airlines and Midwest Airlines under Republic Airways marked an attempt to create a major carrier. While this venture did not unfold as planned, it set the stage for future developments in the airline industry.


2010: United and Continental

United Airlines and Continental Airlines announced a game-changing merger valued at $3 billion. This strategic move strengthened United's geographic presence, making it the second-largest U.S. airline by seats and reinforcing the trend of consolidation for increased profitability.


2011: Southwest and AirTran

Southwest Airlines' acquisition of AirTran Airways for $1.37 billion facilitated its entry into the southeast and international markets. Approved in 2011, this merger showcased the importance of geographical expansion for major carriers.


2013: US Airways and American

In a landmark $11 billion deal, US Airways and American Airlines merged to form the largest U.S. airline by seats. This transformative move underscored the significance of scale in the face of industry changes and challenges.


2016: Alaska and Virgin America

Alaska Airlines disrupted JetBlue's growth plans on the West Coast with its acquisition of Virgin America for $2.6 billion. This strategic move expanded Alaska's presence in key markets, emphasizing the competitive dynamics among major carriers.


Pending Mergers

JetBlue and Spirit

A bidding war unfolded as JetBlue countered Frontier's bid for Spirit Airlines with a $3.8 billion offer. If approved, this merger would position JetBlue and Spirit as the fifth-largest U.S. airline, showcasing the ongoing trend of consolidation.


Alaska and Hawaiian

In a recent surprise move, Alaska Airlines announced a $1.9 billion deal to acquire Hawaiian Airlines. If successful, this merger, expected to close by June 2025, would solidify the new entity as the fifth-largest U.S. airline, further reshaping the industry.
