Do you have to go through airport security during a layover?

Navigating Airport Security During Layovers

When planning a trip that involves a layover, understanding the security procedures is crucial for a smooth travel experience. The need for additional security screening during a layover depends on several factors, primarily your itinerary and the airport layout.

Seamless Connections and Security Bypasses

If your connecting flights are within the same terminal and you have a seamless connection (without leaving the secure area), you may not need to go through security again. This is because you remain within the sterile zone and your luggage has already been screened.

Domestic Connections and Security Checkpoints

However, for most domestic connections, even with a short layover, you will likely need to go through a security checkpoint before boarding your onward flight. This is because the sterile zones in different concourses or terminals may be separated, requiring you to exit and re-enter the secure area.

International Connections

The security procedures for international connections can vary depending on the airport and airlines involved. In most cases, you will need to go through security again, as you will likely have to collect your luggage and clear customs before connecting to your onward flight.

Checking Your Itinerary

The best way to determine whether you will need to go through security during a layover is to check your itinerary. If it indicates a “security check,” you will need to factor in extra time for that process.

Tips for a Smooth Layover

• Allow ample time for your layover, especially if you anticipate needing to go through security.
• If possible, book connecting flights within the same terminal or concourse.
• Pack your carry-on luggage carefully, following TSA regulations.
• Be prepared to remove your shoes, belt, and any electronics from your bag for screening.
• Follow the instructions of the TSA agents and be patient.
