If you need airport parking, save time and plan ahead by shopping the lot that's right for you at . Real-time parking lot availability, a helpful tool for travelers, is shown on our homepage, as well as on Super Park's site.

Know before you go- and read the information below to help expedite the TSA screening process.

ID Requirements

Passengers age 18 and over must show valid Government-issued identification at the TSA security checkpoints in order to travel.  These include a driver’s license, U.S. Passport, DHS trusted traveler card or U.S. Military ID.   For full list, visit    

For domestic travel, the TSA will accept non-expired Driver’s Licenses from any state through 2017.

Beginning January 22, 2018, driver’s licenses or state IDs issued by states that are not in compliance with the federal REAL ID Act, may not be used to fly within the U.S. At this time, Missouri IDs are not compliant. To find out the status of your state, and to learn more, please visit

A passport is, and will continue to be required, for all international travel.

Liquids Rule

Travelers are allowed to bring a quart-sized bag of liquids, aerosols, gels, creams and pastes in your carry-on bag and through the checkpoint. These are limited to travel-sized containers that are 3.4 ounces (100 milliliters) or less per item. Placing these items in the small bag and separating from your carry-on baggage facilitates the screening process. Pack items that are in containers larger than 3.4 ounces or 100 milliliters in checked baggage.

Any liquid, aerosol, gel, cream or paste that raises alarm during screening will require additional screening.
