Moving through the TSA security checkpoint can be complicated. But the TSA has modified screening procedures in place for important personal items. All items, including strollers, car seats, and backpacks must be screened by X-ray. Breast milk, powdered formula, baby food and snacks, bottles and juice in reasonable quantities are all permitted through the checkpoint. This exemption also applies to liquid and cream medications. Travelers are asked to separate these items from your bag and place into a separate bin for X-ray screening.

Additional details on the security screening process can be found here.

  • The Federal Aviation Administration (FAA) recommends that infants and small children who weigh under 40 pounds be secured in an FAA-approved car seat or harness-type device when traveling by air. Approved car seat style child restraint systems will have one or more of the following labels:
    • An FMVSS.213 insignia
    • Language indicating that they are certified or approved for use in motor vehicles and on aircraft
    • Language indicating that they conform to all applicable federal motor vehicle safety standards
    Although the width of aircraft seats varies, a car seat style child restraint system wider than 17.88 inches is unlikely to fit and provide maximum protection for your child. Backless booster seats, safety belt extensions (commonly referred to as “belly belts”) and vest or harness devices that attach to an adult are banned for use on aircraft by the FAA. If your child will not be seated in his or her car seat during the flight, you may either:
    • check the car seat as checked baggage at the time of check-in at the ticket counter and retrieve it at baggage claim upon arrival or;
    • gate check the car seat during boarding and retrieve it at the gate or passenger loading bridge upon arrival at your destination.
    There is no charge for checking or gate-checking one car seat per fare-paying passenger. You may check a stroller as checked baggage at the time of check-in at the ticket counter or gate-check it during boarding. There is no charge for checking or gate-checking one stroller per fare-paying passenger. Gate-checked strollers will be stowed in the cargo hold of the aircraft during the flight and delivered to the gate or passenger loading bridge upon arrival at your destination.

Food and drink for all ages is available at the airport’s concession area. There is also a vending machine located near Gate 2.

A standard ticket on Allegiant Airlines does not include the reservation of a specific seat. While the airline will do their best to accommodate families, the availability of seats together cannot be guaranteed. To ensure your family sits together, consider reserving seats when you book.

Wheelchair assistance is provided by Allegiant Airlines, and passengers must make reservations in advance to use the service. Use the airline’s request form for assistance.

Depending on where you’ve left an item, you will need to contact either the airport or the airline. More details on lost items can be found here.
