Travel slipcovers seem like a great idea. They slip over most transit seats and provide a barrier between you and the presumably germ laden seat. The cover includes a headrest pillow pocket to hold your own travel sized pillow. Unfortunately it won’t stop the coughing guy next to you from spreading the flu. If the germs don’t get you the 100 people waiting in the aisle while you unfold and spread this seat cover just might do you in.
