If you’ve ever been trapped on a plane that feels like the Arctic, you know how miserable it can be to fly without a warm sweater. Especially on long flights, planes tend to crank up the air conditioning to prevent the cabin from getting hot and stuffy from all the passengers’ cumulative body heat. Even if you close the personal air vent above your seat, the cold air can persist from the main AC system, making it harder to relax and get comfortable for your flight.
When you’re on a flight, you may not always be able to walk around to get your blood flowing and raise your body temperature, meaning you can get chilly faster and stay cold longer. This is why you should always carry an extra sweater or lightweight jersey knit cardigan. Look for pieces that are soft and loose-fitting so you don’t feel constricted. Buttoned and open-front options let you easily take them on and off as your body temperature fluctuates.
Even if you don’t need to wear your sweater for the full duration of the flight, you’ll have it with you when you land in case your destination has a cooler climate.
