Except for personal medical oxygen cylinders, you can only carry an EMPTY compressed gas cylinder onboard a plane. To be permitted (in either carry-on or checked baggage), it must be clearly visible to the TSA officer that the cylinder is empty.

For more prohibited items, please go to the 'What Can I Bring?' page.

The final decision rests with the TSA officer on whether an item is allowed through the checkpoint.
