If you’ve ever shivered your way through a flight before, you’re not alone. In fact, plenty of travelers know the feeling all too well: Airplanes can get really, really cold. But, despite the discomfort, this drop in temperatures isn’t just random. There are many reasons for a cold cabin, including for reducing the risk of dehydration at high altitudes, preventing passengers from fainting because of pressure changes, and accommodating the different body temperatures in a plane full of people (it’s a lot easier to add layers if you’re cold than to try and cool down if you’re too warm).
And while some passengers might resort to just bringing a TSA-approved extra blanket onboard, wearing cozy socks, or packing their favorite hoodie (even if they’re traveling to a much hotter destination), these added precautions aren’t always enough for people who get cold easily. Especially when you consider the fact that some seats might feel colder than others on an airplane, depending on their location.
Thankfully, though, the Transportation Security Administration (TSA) allows passengers to bring one more item that can help solve the issue: hand and foot warmers. Typically used for camping, hiking, and other outdoor activities, these warming packs are approved for both carry-on and checked baggage (with some exceptions) according to their regulations. Available in several different styles — including air-activated types that use iron powder, reusable gel and liquid-based warmers, and battery-powered options — most hand and foot warmers are all designed with one common goal in mind: to generate enough heat that’ll keep your hands and feet toasty for hours.

Other ways to stay warm on a flight
Beyond hand warmers, staying cozy on a flight doesn’t have to be a battle of discomfort and frustration. As an overall strategy, layering is still one of the most effective ways to regulate your temperature — even when cabin temperatures start to fluctuate. Ideally, you’ll want to start with a moisture-wicking base layer that keeps sweat away from your skin, then add an insulating middle layer like a light sweater, and top it all off with a removable outer layer that you can put on and take off as needed.
Along with that, a large scarf or shawl is also one of the best things you can wear on a flight. Whether you can use it as a wrap around your shoulders, a makeshift blanket, or even roll it up as a pillow, having an extra removable layer handy can help you adjust a lot easier than if you were only traveling with a large jacket or hoodie (too hot!).
Finally, staying hydrated during your flight is also essential for regulating body temperature. Although typically associated with feeling hot and sweaty, dehydration can sometimes make you feel colder than you actually are. That said, try your best to avoid any excess alcohol and caffeine (both of which can contribute to fluid loss), and pack some extra hydration tablets in your carry-on to help you stay properly hydrated throughout your entire journey.
