Travel tips from the U.S. Transportation Security Administration

In some cases, screeners open your checked baggage as part of the security process. The TSA suggests that you leave your checked baggage unlocked to help avoid breakage of your luggage locks. If your bag is locked and the TSA screeners request an inspection, the locks may be broken. You can lock your bags at your own will but TSA will not be responsible for any damage that may occur to locked bags when opened for security procedures. Whenever TSA screeners open your bag, they will place a tamper-evidence seal on the outside and leave a notice inside to signify that they have inspected it.

There are some so-called dual-use items that could possibly become weapons and cannot be carried onboard the aircraft in your hand luggage or allowed past security checkpoints. Please check the TSA's list of banned carry-on items before you travel.

For information about the TSA security procedures, packing, and timesaving tips, please visit U.S. Transportation Security Administration. If you need to report lost or missing items that may have been left at a TSA screening or baggage checkpoint, or in case there has been damage to your luggage or its contents, this page provides links to Lost and Found departments and to the TSA Claims Management Office. It also provides links to download the forms needed to report lost/missing items or damage related to TSA security procedures. These forms can be submitted online or mailed to: TSA Claims Management Office, 601 So. 12th Street—TSA 9, Arlington, VA 22202. You can call the TSA Contact Center with questions or to inquire about loss or damage claims toll-free at (USA) 1-866-289-9673, or email

Please note that you should contact the last airline flown with if your luggage is missing, not the TSA.

Canada (Notice from CATSA, the Canadian Air Transport Security Authority)

Your checked bags will be screened and may be physically searched. Although you may lock bags on flights departing Canadian airports, please note:

  • Screening officers are not allowed to break locks: they can, however, use special tools to open and re-secure recognized and accepted travel locks.
  • These locks are widely used in the United States and other countries and can be purchased at travel stores, airports and retailers in Canada and abroad.
  • Ask your retailer and read the packaging to confirm the locks that can be opened by airport security agencies before you buy them.
  • If screening officers cannot open your lock, they will ask an airline representative to try to locate you so that you can provide the required key or combination.
  • If you cannot be found, the airline representative may break the lock to allow a physical search of your checked bag.
  • Any bag that requires a search but cannot be opened will not clear security.
  • Checked bags that do not clear security are returned to the airline.
  • If your checked bag is opened for a physical search, a “Notification of Checked Baggage Inspection” card will be placed inside.
  • CATSA assumes no liability for damage to personal property resulting from this necessary security measure. We appreciate your understanding and cooperation.
