Many common items used everyday in the home or workplace may seem harmless. However, when transported by air, they can be very dangerous. In flight, variations in temperature and pressure can cause items to leak, generate toxic fumes or start a fire.

Refer to the chart below to determine if items you plan to bring with you are allowed for air transportation. Items which are listed below as restricted for transport by air will be confiscated by the TSA.

Continental Airlines Things To Know About Your Carry-on Bags
When you bring your bag onboard, you save time - avoid lines at the check-in counter and waiting at baggage claim - so you can ease in and out of the airport.
If you are traveling with any liquid, gel or aerosol items, here's a few things you should remember:
Customers departing from U.S. airports on any domestic or international flight may bring carry-on bags through security and aboard the aircraft with trial-size toiletries (3.4 ounces or less) which can be purchased at any drug store.
Toiletries must fit comfortably in one, quart-size (7.5" x 8"), clear plastic zip-top bag.
The zip-top bag may need to be presented separately at airport security so make sure it is easily accessible when you approach the screening area.
Additionally, beverages or toiletries purchased inside the airport beyond the security checkpoints will be allowed onboard the aircraft.
Items greater than 3.4 ounces and/or not contained in a zip-top bag may be allowed on board but must be declared to the TSA at the security checkpoint for screening. These items include baby formula, milk (to include breast milk), baby food, juice, medications and liquids/gels that are needed for diabetic or other medical conditions.
Restrictions vary for flights departing from non - U.S. locations. Travelers should check with the departure airport for specific security restrictions.
It's always a good idea to check the airport processing times before departing for the airport to ensure that you allow enough time for additional processing when required.
Please note, customers are prohibited from bringing aboard any device to alter or limit the functionality (permanently or temporarily) of any aircraft structure, seat assembly, tray table, etc.
Additional references with detailed information and examples of allowable items may be found at the TSA's Web site.
