Blumenthal & Garamendi Reintroduce Legislation To Protect Passengers And Crew From Toxic Cabin Air

[WASHINGTON, D.C.] - U.S. Senator Richard Blumenthal (D-CT) and U.S. Representative John Garamendi (D-CA), a senior member of the House Committee on Transportation and Infrastructure, today announced the reintroduction of the Cabin Air Safety Act, bicameral legislation to protect airline pilots, flight attendants, and passengers from toxic cabin air. Building on cabin air reporting provisions Blumenthal secured in the Federal Aviation Administration (FAA) Reauthorization Act of 2024, the legislation would expand FAA reporting and investigation requirements, require real-time onboard air quality monitoring equipment, improve crew training, and enhance the collection and public reporting of data on engine oil and hydraulic fluid smoke or fume events to help prevent future incidents and improve aviation safety.

"For too long, dangerous cabin air events have gone underreported, under investigated, and unaddressed," said Blumenthal. "Our measure gives the FAA the tools it needs to identify these events in real time, ensure they are properly reported and investigated, and take steps to prevent them from happening in the first place. Pilots, flight attendants, aircraft mechanics, and passengers deserve to know that the air they breathe is safe."

"Every American deserves safe, clean air when they fly. I'm deeply troubled by the reports of pilots, flight attendants, and passengers falling ill, and in some cases even hospitalized, due to toxic cabin air. This legislation will hold aircraft manufacturers to a basic safety standard: protecting passengers and crew from harmful toxins," said Garamendi.

The legislation is cosponsored by U.S. Senators Edward J. Markey (D-MA) and Tammy Duckworth (D-IL).

"Airline crew members and passengers have the right to breathe safe, clean air, on the ground and in the air. They should never have to worry about breathing in toxic air pollutants that put their health at risk," said Markey. "I'm proud to join Senator Blumenthal in introducing the Cabin Air Safety Act to ensure we put the health, safety, and wellbeing of our crewmembers and passengers first."

"The flying public deserves certainty that the air they breathe during their flight isn't jeopardizing their health and safety," said Duckworth. "When toxic fumes leak into the cabin, it could lead to health issues for passengers and potentially dangerous impairments to the pilots and crew. Our commonsense legislation would equip every cabin with air quality monitors and help prevent these incidents from happening."

The legislation establishes a new chapter dedicated to cabin air quality and safety, with five key provisions:

• Mandatory Air Safety Training: Mandates that pilots, flight attendants, aircraft technicians, and airport emergency first responders receive detailed training to recognize, manage, and report toxic smoke, hazardous fumes, and air contamination incidents on aircraft.

• Standardized Reporting & Public Portal: Directs the FAA to implement a standardized system for crew members to report smoke and fume incidents. The FAA must maintain a searchable, online public database of aggregate, anonymized incident data.

• Incident Investigations: Authorizes the FAA to conduct official investigations into air contamination events and requires an investigation whenever an incident results in crew members or passengers needing medical attention beyond basic first aid.

• Onboard Air Monitoring & Detection: Directs air carriers to install and operate real-time detectors and air quality monitoring equipment within the air supply system to identify contamination sources and alert flight crews to hazardous air conditions.

• Air Quality Standards & Rulemaking: Authorizes the FAA to establish aircraft cabin air quality standards and specific maintenance requirements to mitigate air supply contamination and protect public health.

The Cabin Air Safety Act is endorsed by the AFL-CIO Transportation Trades Department (TTD), Association of Flight Attendants-CWA, International Association of Machinists and Aerospace Workers (IAMAW), Air Line Pilots Association (ALPA), Transport Workers Union (TWU), Association of Professional Flight Attendants (APFA), International Brotherhood of Teamsters, National League of Consumers, American Association for Justice (AAJ), and the American Lung Association.

"No worker in this country should have to show up to their place of employment knowing it could make them sick-yet pilots, flight attendants, and cabin crew members remain at risk of breathing in unhealthy air contaminants on the job. As America's largest transportation labor federation, we strongly support the measures in the Cabin Air Safety Act to protect commercial aviation and air cargo workers, as well as the flying public, from toxic fumes," said Greg Regan, President of AFL-CIO TTD.

"ALPA is grateful to Senator Blumenthal for his continuing effort in the fight to keep our skies safe and healthy. While we have been making progress on helping our industry facilitate open discussions around research, education, standardized reporting, and data collection of air quality or fume events aboard aircraft, it is time to stop ignoring these serious events and start protecting passengers and crew from any hidden and toxic fumes. For too long, cabin air events have gone uninvestigated and the underlying causes have gone unaddressed. This bill would finally give the FAA the tools, and the mandate, to monitor, investigate, and prevent these events before they put a crew or their passengers at risk," said Capt. Jason Ambrosi, President of ALPA.

"The Transport Workers Union strongly supports the Cabin Air Safety Act, which builds on the most recent FAA reauthorization by requiring air quality monitoring equipment that allows flight attendants and aircraft mechanics to identify the sources of toxic cabin air in real time," said Andre Sutton, TWU Air Division Director.

"Most Americans go to work with the expectation of breathing clean air, but until we achieve better standards for cabin air quality, Flight Attendants don't have this guarantee. We applaud Senators Blumenthal, Markey, and Duckworth and Congressman Garamendi for introducing the Cabin Air Safety Act of 2026. We encourage their Senate colleagues to cosponsor this bill ASAP," said Sara Nelson, President of the Association of Flight Attendants-CWA. "Crews and passengers are breathing toxins and it has got to stop. The first step in the solution is training and thorough identification of the problem as defined by this bill. Often crew and passengers have no idea why they feel ill and no guidance on how to get treated. This bill gives us the tools to prevent Flight Attendants, pilots or passengers from suffering the effects of breathing toxic fumes in the cabin."
