Security screening of passengers at American airports is overseen by the Transportation Security Authority (TSA), an agency of the U.S. Department of Homeland Security that has authority over the security of the traveling public in the United States. TSA works closely with intelligence and law enforcement communities to achieve the highest levels of transportation security for the safety of all travelers.
What can I bring?
Plan ahead by ensuring you pack your carry-on and checked baggage with permitted items. TSA provides a full list of what can and cannot be checked through security. You can search categories like flammables, firearms, food, household and tools, medical, sharp objects, sporting and camping, and miscellaneous items such as baby carriers, electronics and personal items.
If an item is not listed, simply snap a picture or send a question to AskTSA on Facebook Messenger or Twitter. TSA answers questions between 8 am and 10 pm EST on weekdays and between 9 am to 7 pm on weekends or holidays.
Note: The final decision rests with the TSA officer as to whether an item is allowed through the TSA security checkpoint.
TSA allows you to check travel-sized containers of liquids, aerosols, gels, creams and pastes inside a quart-sized resealable bag in your carry-on bag and through the security checkpoint. Each travel-sized container should not exceed 3.4 ounces (100 millilitres). Anything larger should be packed in your checked baggage.
We encourage you to visit the TSA website to review more details about the Liquids Rule, including exemptions about medications and baby formula.
What identification do I need?
Adult passengers 18 and over must show valid identification at the airport security checkpoint in order to travel.
TSA does not require children under 18 to provide identification when traveling with a companion within the United States. Contact Allegiant Air or United Airlines for questions regarding airline-specific ID requirements for travelers under 18.
