First class and business class travelers are given ear plugs to drown out the sound, eye masks to keep it dark and little socks to warm their feet. What do you get in economy? A ticket, a seat, a place to store your bags, and a hot meal and complimentary beverage. Most fliers know that their feet will get cold if they remove their shoes. To avoid cold feet which makes relaxing and sleeping difficult, bring a pair of socks (and preferably a pair you don’t mind throwing out because of dirty airplanes).
