Arrive Early

The TSA advises passengers arrive at the airport 2 hours prior to scheduled boarding time. During peak travel periods, including major holiday travel times, please allow for more time than normal when arriving to the airport.

If you need airport parking, save time and plan ahead by shopping the lot that's right for you at www.SuperParkingLot.com . The site also features real-time parking lot availability, which can be a helpful tool for travelers.

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, i.e., driver’s license, U.S. Passport, DHS trusted traveler card or U.S. Military ID. For full list, visit https://www.tsa.gov/travel/security-screening/identification.   

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.
