9 Surprising Things NOT Allowed on a Plane

6. Butane Curling Irons

Here’s a beauty item you may want to have with you when traveling—a cordless curling iron. It’s very easy to use and heats up quickly, so why not, right? Well, you may want to reconsider this idea and go for a classic curling iron (one that has a cord).

Cordless curling irons use butane, and while they are allowed in a carry-on bag, you can’t bring one with you in your checked bag. The reason? The iron could easily catch fire if it accidentally turns on.

Now, if you want to bring the curling iron onto the plane, make sure it has a safety cover over the curler, just in case. Additionally, according to TS, spare cartridges (or gas refills) aren’t allowed in either carry-on or checked bags.
