When I have a connecting flight, do I have to go through security again?

Navigating Security Checks during Connecting Flights

When planning a trip involving connecting flights, one common concern is whether you will need to undergo security checks multiple times. Understanding the protocols for different types of connections can help you plan your travel accordingly.

Domestic Connecting Flights

Generally, when connecting between two domestic flights at the same airport, you will not need to go through security again. Once you have cleared security at your departure airport, you can remain in the secure area and proceed to your connecting gate. However, there are exceptions to this rule.

At some airports with disconnected terminals, you may need to exit the secure area to reach your connecting terminal. In such cases, you will need to go through security again. For example, at airports like Dallas/Fort Worth International Airport (DFW) and Atlanta Hartsfield-Jackson International Airport (ATL), passengers connecting between terminals may need to undergo a secondary security check.

Domestic-to-International Connecting Flights

For domestic-to-international connections, the likelihood of re-entering security is lower. Most U.S. airports have dedicated international terminals or areas, and passengers can typically remain in the secure area while transferring between domestic and international flights. However, if your connecting flight departs from a different terminal, you may need to exit the secure area and go through security again.

Tips for Minimizing Security Checks

To minimize the potential for multiple security checks during connecting flights, consider the following tips:

• Check if your connecting airport has disconnected terminals. If so, allow ample time for security screening at the connecting terminal.
• If possible, choose connecting flights that depart from the same terminal as your arrival flight.
• If you are connecting between domestic and international flights, determine whether your connecting flight departs from the same international terminal or a different one.
• Pack your carry-on luggage efficiently to minimize the risk of delays during security checks.
• Stay informed about the latest security regulations and restrictions at your departing and connecting airports.

By understanding the protocols for security checks during connecting flights, you can plan your travel more efficiently and minimize any potential delays.
