What kind of photo identification is accepted when checking-in for my flight?
Please refer to for ID Requirements for Airport Checkpoints:

Do I need a passport in order to board the plane?
If you are flying within the U.S. you do not need a passport in order to board a plane. However, passports are government issued forms of identification that can be used when checking in to your flight.

Can I bring food and beverage onto the flight?
TSA guidelines state that, “All food must go through the X-ray machine. Do NOT bring food to the security checkpoint unwrapped. Food must be wrapped or in a container. Unpeeled natural foods like fruit are okay, but half-eaten fruits must be wrapped.” Beverages purchased after the security checkpoint can also be brought onto the plane. TSA regulations prohibit bringing any beverages in containers over 3 ounces through the security checkpoint.

Arrivals and Departures
Arrival and Departure information can be found on the Flight Status page.

Where can I meet arriving passengers?
You can meet arriving passengers inside the STS terminal, outside at the gate between the restaurant patio and the terminal, or in front of the terminal.

This is a small airport. Why do I have to arrive so early to depart?
STS is a small airport, but flights connect to large hubs. It takes time to screen and board passengers. It is important to get everyone on board so the aircraft can depart on time. Too often we see passengers who cut it too close miss their flights. Sometimes they wait in the lobby too long before going through Security and miss their flights!

Can I accompany a passenger through Security screening to the boarding area?
Yes, under certain conditions. If a passenger requires an escort due to disability or age, an escort must obtain a security pass at the check in counter and go through security screening to accompany the passenger to the boarding area. Security passes are limited and typically one pass is issued per passenger requiring an escort.

Disabled Services

What services are available to assist disabled passengers?
Airlines are pleased to provide assistance for travelers who require Mobility/Wheelchair assistance. To provide the optimal experience, it is recommended that all travelers:

Make their reservations as early as possible; services can be requested online or over the phone.
Arrive at the airport at least 2 hours prior to departure when requesting these services. Advise a Customer Service Agent (CSA) of any special requirements when checking in at the airport.

Are service animals allowed on the plane?
Yes. At no time during the screening process will you be required to be separated from your service animal.

If you are traveling with a service animal, please inform the Transportation Security Officer (TSO) that the animal is a service animal. You will be requested to maintain control of your service animal during the entire screening process.

If, after screening, you need to go back outside to relieve your animal, upon returning to the screening checkpoint you must undergo the entire screening process again. However, you may inform the TSO upon your return to the screening checkpoint and he or she will make every effort to move you to the front of the line.

Even if an item is generally permitted, it may be subject to additional screening or not allowed through the checkpoint if it triggers an alarm during the screening process, appears to have been tampered with, or poses other security concerns. The final decision rests with TSA on whether to allow any items on the plane.
