You’ll have to skip traveling with an arc, plasma, or e-lighter, whether in a checked or carry-on bag. A disposable or Zippo lighter in your carry-on won’t pose a problem, but it must be empty if checked. There’s one exception: Those willing to go through the headache of getting a special Department of Transportation (DOT)-approved carrying case can pack and check up to two filled lighters.
Checked Bag: Yes, With Restrictions
Carry-On: Yes
