How Safe is the Air Conditioning on a Plane?

ByRalph P. Sita Updated onJanuary 20, 2025

Flying can often be a stressful experience, but one aspect you don’t need to worry about is the safety of the air conditioning system on an aircraft. These systems are meticulously regulated to meet stringent safety standards, ensuring that they are designed to maintain both comfort and health. The air on airplanes is a mix of fresh outdoor air and recirculated indoor air, and it’s quite safe to breathe. While it’s true that some passengers may experience discomfort, such as headaches or nausea, due to the recirculated air, these occurrences are rare. For those sensitive to this, simple solutions like using a high-quality travel pillow and blanket can help create a more comfortable environment, allowing you to enjoy a fresher, more pleasant flight experience.

What are the Risks of Contracting a Disease from the Air Conditioning on a Plane

When you’re flying, the last thing you want to worry about is getting sick.

But unfortunately, the air conditioning on planes can sometimes spread disease.

Here’s what you need to know about the risks of contracting a disease from the air conditioning on a plane – and how you can protect yourself.

The air on airplanes is circulated through a central system that pulls in fresh air from outside and mixes it with recirculated air from inside the cabin.

This allows airlines to save fuel by not having to pump in new, fresh air constantly.

However, it also means that any germs or viruses present in the cabin can quickly spread throughout the entire aircraft.

One of the most common diseases contracted through airplane AC is influenza.

In fact, one study found that during flu season, up to 30% of passengers on long-haul flights were infected with the virus after just four hours in flight!

The good news is that you can take steps to protect yourself from getting sick when flying.

First, make sure to get a flu shot before your trip. And during flu season, try to avoid sitting near someone who appears ill.

Second, wash your hands often and use hand sanitizer when soap and water are not available.

Finally, try to avoid touching your face (especially your eyes, nose, or mouth) while on the plane.

The exact risks are not known because it is difficult to study this issue, but it is clear that there are some risks involved.
