Do you have to go through security again for connecting international flights at SFO?

Navigating Connections at SFO: The Inevitable Security Rescreening

San Francisco International Airport (SFO) is a major hub for international travel, connecting passengers from around the globe to destinations worldwide. However, for those transferring between international and domestic flights (or even between two international flights), a crucial detail often causes confusion: you will have to go through airport security again.

Unlike some airports that offer streamlined processes for connecting international passengers, SFO requires a complete re-screening for all connecting international flights. This is not an optional step; it’s a mandatory procedure enforced by federal regulations.

This process involves several distinct phases:

1. Federal Inspection: Upon arrival at SFO on an international flight, all passengers must clear U.S. Customs and Border Protection (CBP) inspection. This involves presenting your passport, visa (if required), and customs declaration form. Be prepared for potential questioning regarding your itinerary and the purpose of your travel.

2. Exiting the Secured Area: After clearing CBP, you will officially exit the secured area of the airport. This means you’ll be in the public concourse, alongside arriving and departing passengers on domestic flights. This is the point where many are caught off guard. Don’t assume your journey through security is complete.

3. Re-screening at TSA: Once you have your baggage (if checked through), you must proceed to a Transportation Security Administration (TSA) checkpoint. This involves the standard security procedures: removing electronics, liquids, and belts; placing items in bins; and walking through the metal detector or body scanner. Be prepared for potential wait times, especially during peak travel periods.

There are no exceptions to this rescreening process at SFO for connecting international flights. Even if you have a tight connection, planning extra time to navigate these three stages is absolutely vital to avoid missing your connecting flight. Factor in potential delays at CBP or TSA, as well as the time needed to travel between terminals.

Planning for Your Connection:

• Check your connecting flight time carefully: Allow ample time between flights to account for the re-screening process. Aim for a minimum of two hours, and more if your connecting flight is on a different terminal.

• Familiarize yourself with SFO’s terminal layout: Understanding the location of CBP, baggage claim, and the TSA checkpoints for your connecting gate is crucial for efficient navigation. Use SFO’s online maps and resources to plan your route beforehand.

• Prepare for security: Ensure you comply with TSA guidelines regarding prohibited items to avoid delays. Having all necessary travel documents ready will also expedite the process.

By understanding the requirement for complete security rescreening at SFO for international connecting flights and adequately preparing for it, you can avoid unnecessary stress and ensure a smoother journey. Plan ahead and enjoy your travels!
