What Can I Bring?

Planning ahead and packing properly can facilitate the screening process and ease your travel experience at the airport. Know what you can pack in your carry-on and checked baggage before arriving at the airport by reviewing the lists below. Even if an item is generally permitted, it may be subject to additional screening or not allowed through the checkpoint if it triggers an alarm during the screening process, appears to have been tampered with, or poses other security concerns. Read about civil penalties for prohibited items.

For items not listed here, simply snap a picture or send a question to AskTSA on Facebook Messenger or Twitter. We look forward to answering your questions, from 8 a.m. to 10 p.m. ET weekdays; 9 a.m. to 7 p.m. weekends/holidays.

 

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

Medical Marijuana

  • Carry On Bags: Yes (Special Instructions)
  • Checked Bags: Yes (Special Instructions)

Marijuana and certain cannabis infused products, including some Cannabidiol (CBD) oil, remain illegal under federal law except for products that contain no more than 0.3 percent THC on a dry weight basis or that are approved by FDA. (See the Agriculture Improvement Act of 2018, Pub. L. 115-334.)  TSA officers are required to report any suspected violations of law to local, state or federal authorities. 

TSA’s screening procedures are focused on security and are designed to detect potential threats to aviation and passengers. Accordingly, TSA security officers do not search for marijuana or other illegal drugs, but if any illegal substance is discovered during security screening, TSA will refer the matter to a law enforcement officer.


Medical Masks

  • Carry On Bags: Yes
  • Checked Bags: Yes

You may wear medical masks during security screening. However, please remove the mask when you arrive at the checkpoint until the TSA officer has verified your identity.


Medically Necessary Personal Oxygen

  • Carry On Bags: Yes (Special Instructions)
  • Checked Bags: No

You may bring personal medical oxygen cylinders through the screening checkpoint and into the gate area. However, personal medical oxygen cylinders are not permitted in the aircraft cabin as they are considered hazardous materials by the Federal Aviation Administration.

Please contact your airline for instructions on arranging oxygen service. Airlines are not required to provide oxygen service and many do not.
