The short answer
You can bring one disposable or Zippo-style lighter in your carry-on or pocket. Torch, jet and blue-flame lighters are banned from both carry-on and checked bags. In checked bags, lighters are allowed only with no fuel, or up to two fueled lighters in a DOT-approved case.

Why checked bags are stricter
The fuel in a lighter is a fire risk in the cargo hold, where a fire can’t be seen or reached. In the cabin, a single lighter is considered manageable. That is why TSA lets you carry one but restricts what you can check.
Electric lighters
Arc, plasma and rechargeable electric lighters contain lithium batteries, so they follow battery rules: carry-on only, with a safety cap or switch lock to stop them turning on.
