There's nothing better than napping on a plane since it's good to rest while making time go by much faster. That means a blanket is a much-needed item, but you might want to stay away from the provided plane blankets. Although they often appear clean, they might not have been washed as thoroughly as you'd like. Thankfully, packing your blanket is easy enough, and you can use it as needed.
Since airlines focus on efficient travel, cleanliness isn't always at the top of their list, but bringing a clean blanket can ensure you stay warm and germ-free on your journey.
