Do you have to go through security again for a connecting flight in the USA?

Navigating Security for Connecting Flights in the USA

When traveling within the United States, connecting flights often raise questions about the need for additional security screenings. Understanding the guidelines can save you valuable time at the airport.

Domestic Connections

For domestic connections within the United States, the general rule is that you do not need to go through security again. This is because most major airports have secure connections that allow you to transfer between terminals without having to re-enter the general security area.

However, there are a few exceptions to this rule:

• Airports with Disconnected Terminals: In some airports, like Chicago O’Hare (ORD), different terminals are not connected securely. If your connecting flight departs from a different terminal, you will likely have to go through security again.

Domestic-to-International Transfers

For domestic-to-international connections, the rules are slightly different. While it is uncommon, you may need to go through security again in the following cases:

• Flying to a High-Risk Destination: If your connecting international flight is bound for a high-risk destination, such as certain countries in the Middle East or Africa, you may be subject to additional security screening.
• Change in Airlines: If you are changing airlines for your international flight, you will likely need to go through security again.

Minimizing Travel Delays

To minimize travel delays when connecting flights within the USA, consider the following tips:

• Check with Your Airline: Before traveling, contact your airline to confirm whether or not you will need to go through security again.
• Allow Ample Time: If you are unsure about the security screening requirements for your connection, give yourself plenty of time to allow for potential delays.
• Use TSA PreCheck or Global Entry: If you have TSA PreCheck or Global Entry status, you may be able to speed up the security screening process.

Remember, security regulations can change without notice. Always check with your airline or the Transportation Security Administration (TSA) for the most up-to-date information.
