9 Surprising Things NOT Allowed on a Plane

5. Gel Insoles

This is definitely one of the weirdest things that the TSA won’t let you bring on a plane. For quite a long time, they banned both gel shoe inserts and gel insoles, which are known to relieve back and foot pain.

But now, surprise! According to the TSA website, these items are now allowed, despite exceeding the 3.4-ounce limit on carry-on liquids. Be careful, though, as it’s a really touch-and-go situation.

While some have succeeded in passing the security checkpoint with gel insoles in their carry-on luggage, others have not. So, unfortunately, passengers will just have to experience it for themselves to see how their airport TSA responds.
