What are the requirements of TSA PreCheck for flying on Southwest?

If you're planning to fly with Southwest and want to breeze through security, TSA PreCheck is a great option. But before you can enjoy the perks, you need to meet the Southwest Airlines TSA requirements.

👉 Requirements needed for Southwest Airlines:

➤ Eligibility: TSA PreCheck is available for U.S. citizens, U.S. nationals, and lawful permanent residents. Applicants should meet certain security standards, so be sure to provide accurate information on your application.

➤ Identification Requirements:

❖ REAL ID: Starting May 7, 2025, you will need a REAL ID-compliant driver's license, state-issued enhanced driver's license, or another TSA-accepted form of ID to travel domestically. Without it, you may face delays and additional screening.

❖ Domestic Travel: If you're flying within the U.S., adults 18 and older need a valid ID that matches the name on your booking. Kids under 18 don't need ID unless they're unaccompanied or lap children, but proof of age might be needed.

❖ International Travel: For international flights, make sure you have your passport and check it with a Southwest agent or kiosk at least 60 minutes before departure. Also, have any other necessary documents for your destination.

➤ TSA PreCheck Lane: At participating airports, TSA PreCheck offers a quicker route through security. Look for the TSA PreCheck indicator on your boarding pass and children under 12 can use the PreCheck lane with an eligible guardian.

➤ Airport Information: Make sure to arrive early, as TSA wait times can change. For Southwest international flights, allow at least 60 minutes for passport checks. There are service animal areas, and staff will assist if needed.

Fond Tip: Make sure your flight booking name matches your government-issued ID to avoid issues at security. Even small discrepancies can cause delays!
