Air Line Pilots Association

The Air Line Pilots Association, International — universally known as ALPA — is the largest airline pilot union in the world, representing more than 78,000 commercial airline pilots at 40 airlines across the United States and Canada. Founded in 1931, ALPA has shaped aviation safety standards, negotiated pilot compensation and work rules, and influenced federal aviation regulation across nine decades of commercial aviation history.

What Is ALPA?

ALPA is a labor union affiliated with the AFL-CIO in the United States and the Canadian Labour Congress. Its membership encompasses the entire spectrum of commercial aviation: captains and first officers at major network carriers like Delta, United, and American; low-cost carriers like Southwest and JetBlue; regional carriers including SkyWest and Republic Airways; cargo specialists at FedEx and UPS; and Canadian carriers such as Air Canada. Each ALPA-represented airline has its own Master Executive Council (MEC) that negotiates the collective bargaining agreement (CBA) specific to that carrier, while the national organization provides legal, safety, and advocacy resources.

How It Works in Practice

ALPA operates through a democratic structure in which member pilots at each airline elect their MEC, which in turn elects representatives to the national Executive Board. The MECs conduct all direct negotiations with airline management on pay, work rules, scope clauses, scheduling, and retirement benefits. ALPA's central staff in Washington, D.C., provides negotiating support, actuarial analysis for retirement programs, legal counsel, and lobbying on federal legislation.

On safety matters ALPA has a particularly influential role. The association maintains an Air Safety Organization that conducts independent investigations of accidents and incidents, files comments on FAA rulemaking proposals, and publishes technical guidance for member pilots. Following the 2009 Colgan Air 3407 crash, ALPA supported the passage of the Airline Safety and FAA Extension Act of 2010, which tightened pilot qualification requirements and introduced the 1,500-hour ATP rule. ALPA's Washington office consistently advocates for increased rest requirements, updated fatigue science implementation under Part 117, and restrictions on single-pilot commercial operations.

Financially, ALPA functions through dues paid by member pilots, typically a percentage of gross pay. At a major U.S. carrier, annual dues for a senior captain earning $300,000 might be $5,000 to $6,000 per year. These funds support contract negotiations, grievance arbitration, political action, and the Air Safety Organization's investigative work.

Why It Matters

ALPA's influence extends well beyond the contracts it negotiates. Because it represents the workforce at airlines responsible for the overwhelming majority of U.S. commercial aviation, ALPA testimony and technical submissions carry significant weight at the FAA, NTSB, and Capitol Hill. The organization's advocacy contributed directly to the implementation of Crew Resource Management training standards, the strengthening of flight time and duty period regulations, and the establishment of Aviation Medical Assistance Act provisions for in-flight medical emergencies. For individual pilots, ALPA membership provides contract enforcement, back pay and benefits in bankruptcy proceedings, legal defense in certificate actions, and peer support through the Pilot Assistance Program.

ALPA's role in safety advocacy is structured through its Air Safety Organization (ASO), which deploys trained investigator-pilots as party representatives in NTSB accident investigations. When a major accident occurs, ALPA's go-team arrives at the site alongside NTSB and FAA personnel, providing specialized pilot knowledge to the investigation. ALPA also maintains formal positions on virtually every area of aviation rulemaking: its comments on FAA Notice of Proposed Rulemaking (NPRM) documents for Part 117, ADS-B mandates, and reduced crew operations proposals are substantive technical documents prepared by staff engineers, flight operations specialists, and aviation medical professionals. This institutional capacity — effectively a private regulatory analysis bureau funded by pilot dues — gives ALPA a level of technical credibility in the regulatory process that few other labor organizations in any industry can match.

ALPA has also been a vocal opponent of Extended Minimum Crew Operations (eMCO) and single-pilot operations (SPO) proposals that some aircraft manufacturers and operators have advanced as potential future operational models. The union's position, supported by a body of human factors research, is that the two-pilot crew model has been the single most important contributor to the improvement in commercial aviation's safety record over the past 50 years, and that any reduction in minimum crew should meet an extraordinarily high evidentiary burden before regulatory approval. ALPA's engagement on this issue illustrates the broader dynamic between labor advocacy and aviation safety: the union's institutional interests and aviation's safety interests frequently but not always align, and when they do, ALPA's advocacy carries the weight of both a workforce representative and a genuine safety stakeholder.

Key Facts and Figures

• ALPA was founded April 13, 1931; David Behncke was its first president.
• Current membership exceeds 78,000 pilots at 40 airlines in the United States and Canada.
• ALPA-represented carriers transport approximately 90% of U.S. commercial airline passengers.
• The ALPA strike fund has been invoked in labor actions including the United Airlines pilot strike of 1985 and Delta pilot work actions.
• ALPA's political action committee (ALPA PAC) is one of the largest labor PACs in the U.S. aviation sector.
• BALPA (British Airline Pilots' Association) is the UK equivalent; it represents approximately 10,000 pilots and similarly participates in rulemaking and safety advocacy.
