Summary
- FAA does not mandate specific cabin temperature ranges, instead offers guidelines for airlines.
- Airlines have internal temperature policies, can vary widely between carriers.
- Legislative efforts and union advocacy aim to establish enforceable temperature limits.
The regulation of aircraft cabin temperatures in the United States has become an increasingly pertinent issue due to rising passenger complaints and several high-profile incidents of extreme cabin temperatures. Although there is no specific federal regulation dictating exact temperature ranges, the issue has garnered attention from several aviation and labor groups pushing for more formalized standards.

Current guidelines and policies
FAA recommendations
The Federal Aviation Administration (FAA) does not currently mandate specific temperature ranges for aircraft cabins. Instead, it provides general guidelines to ensure passenger comfort and safety. Airlines are encouraged to maintain cabin temperatures between 65°F and 75°F, but this is not enforced by strict regulation.
Occupational Safety and Health Administration (OSHA) standards
While OSHA provides guidelines for workplace environments, including temperature ranges, these do not directly apply to aircraft cabins. Flight attendants and crew members, who are considered employees, may be subject to different standards, but there is no explicit regulation for passenger cabin temperatures.

Ground air, the APU, and engines supply conditioned air to the cabin.
Airline policies
Airlines often have their own internal policies and procedures for managing cabin temperatures. These policies typically aim to maintain a comfortable environment for passengers and crew but can vary widely between carriers. For instance, American Airlines has protocols to ensure cabin temperatures do not exceed 90°F before boarding, but enforcement can vary.

-
Environmental factors
- Cabin temperatures can be affected by various environmental factors, including the aircraft’s location, altitude, and external weather conditions. This variability makes it challenging to enforce a one-size-fits-all regulation.
-
Technical limitations
- Aircraft air conditioning systems have limitations, especially during ground operations. When aircraft are parked at gates or on tarmacs, the air conditioning may not function optimally, leading to higher cabin temperatures.
-
Passenger & crew comfort
- Balancing the comfort of passengers and crew members is another challenge. What feels comfortable to one person may be too hot or cold for another, making it difficult to set a standard temperature that satisfies everyone.

How & Why Do Airlines Control The Temperature Of Their Cabins?
Aircraft cabins can often feel like a walk-in freezer, here’s why.
Ongoing legislative efforts and union advocacy
Legislative efforts
Recent legislative efforts have aimed at establishing more concrete regulations.
“The House-passed version of this year’s FAA reauthorization bill, H.R. 3935, would require the FAA to examine the issue — but only if industry and unions can’t come to a consensus on a safe cabin temperature.
The Senate’s version, S. 1939, would order a study by the National Academies of Sciences, Engineering and Medicine on the health and safety impacts for temperatures less than 65 degrees or more than 85 degrees during “all phases” of flight.
The Senate Commerce Committee has yet to mark up that bill.”
Union advocacy
Unions such as the Association of Flight Attendants-CWA (AFA) have been vocal about the need for stricter temperature controls. They highlight the health risks posed by extreme temperatures, including heat exhaustion and hypothermia, particularly during long delays on the apron. The AFA’s #2Hot2Cold campaign advocates for setting enforceable temperature limits and has garnered significant support from flight attendants and passengers alike.
Airline initiatives
Airlines have taken proactive steps to address cabin temperature issues. According to Tourism Review, American Airlines will not allow passengers to board its planes if the cabin temperature exceeds 32°C (90°F), while JetBlue has set this threshold at 29°C (85°F).
Notable incidents and public pressure
Recent high-profile incidents
Several incidents have brought the issue into the public eye. For instance, according to Fortune, a United Airlines flight in 2017 saw cabin temperatures soar, resulting in severe discomfort and potential health risks for passengers. Similarly, American Airlines faced criticism when a cabin reached temperatures above 90°F before boarding, leading to calls for regulatory action. According to Politico, a JetBlue flight from the Dominican Republic to Boston had to turn back after a malfunctioning air conditioner sent cabin temperatures up to 97°F.

Public pressure
The discomfort caused by extreme temperatures has led to increased public pressure on both airlines and regulators. According to The Points Guy, passengers have frequently reported incidents on social media, prompting broader media coverage and a call for more stringent regulations.
Industry responses
In response to these incidents, airlines have begun reviewing and updating their cabin temperature policies. Enhanced training for crew members on managing cabin air temperatures and investing in better air conditioning systems are some steps airlines can take to prevent such occurrences in the future.
Technical aspects of aircraft cabin temperature control
For our aviation enthusiasts, here’s a closer look at the technical aspects of how cabin temperatures are managed on modern aircraft:
|
Environmental Control System (ECS) |
The ECS is responsible for maintaining the cabin environment, including temperature, humidity, and air quality. It uses bleed air from the engines, which is conditioned and distributed throughout the cabin. |
|
Temperature Zones |
Most modern aircraft are divided into multiple temperature zones. This allows different sections of the aircraft, such as the cockpit, cabin, and cargo hold, to be controlled independently, ensuring optimal comfort for passengers and crew. |
|
Advanced Thermostats |
Aircraft are equipped with advanced thermostats and sensors that continuously monitor the temperature. These systems can automatically adjust the heating and cooling based on real-time data to maintain the desired temperature range. |
|
Heating and Cooling Packs |
The ECS includes heating and cooling packs that adjust the air temperature before it is circulated in the cabin. These packs can rapidly heat or cool the air to respond to changing conditions. |
|
Humidity Control |
In addition to temperature, the ECS also manages cabin humidity. Maintaining appropriate humidity levels is important for passenger comfort and helps prevent dehydration during long-haul flights. |
|
Backup Systems |
Aircraft are equipped with backup systems to ensure temperature control even if the primary ECS fails. These backups are critical for maintaining safety and comfort, especially during extended flights. |
|
Ground Operations |
While on the ground, auxiliary power units (APUs) or ground power units (GPUs) can be used to power the ECS, ensuring the cabin remains comfortable. Ground air conditioning units (GACUs) can also be connected to maintain cabin temperature without using the aircraft’s engines (making it both fuel-efficient and environmentally friendly). |

Future directions
Technological innovations
Advancements in aircraft technology may offer solutions to cabin temperature challenges. Newer models come equipped with more efficient air conditioning systems and advanced climate control features, promising better temperature regulation.
Regulatory developments
As the aviation industry continues to evolve, there is potential for more stringent regulations on cabin temperatures here in the US. Collaboration between airlines, regulatory bodies, and advocacy groups will be crucial in developing standards that ensure passenger comfort and safety.
Passenger awareness
Passengers can also help manage cabin temperatures by dressing appropriately for flights and staying hydrated. Awareness campaigns by airlines and travel organizations can help educate travelers on how to stay comfortable during flights.
Airline initiatives: ensuring a comfortable flight experience
Maintaining a comfortable cabin temperature is vital for a positive flight experience. While current regulations are limited, ongoing efforts by advocacy groups, airlines, and lawmakers aim to establish better standards. Passengers can contribute to a safer and more comfortable flying environment by staying informed and advocating for improved conditions.
