9 Surprising Things NOT Allowed on a Plane

4. Heating Pads

Heating pads sound good when flying on a plane. You just have to plug the pad into the electrical outlet found at the bottom of your chair, and that’s it! This would be especially useful if you were sitting in one of those cramped economy-class seats.

A heating pad on board could relieve your aching shoulders, upper back, and neck. Except for the fact that you can’t bring heating pads on a plane. The reason? The gel found inside is essentially liquid.

So forget about your classic heating pad; you’ll have to stow it in your checked luggage or stick with an electrical heating pad.
