DALLAS-FORT WORTH— American Airlines (AA) has launched the One Stop Security (OSS) program at Dallas-Fort Worth International Airport (DFW), a pioneering step in simplifying U.S. international connections.
Effective July 17, 2025, passengers arriving from London Heathrow (LHR) on American Airlines flight AA51 and connecting onward at DFW can bypass traditional customs, baggage recheck, and TSA security screening.

American Airlines Trials OSS Passengers
The One Stop Security (OSS) program, now live at DFW, represents a significant advancement in U.S. airport processing for international passengers.
American Airlines, the first U.S. carrier to implement OSS, launched this initiative with flight AA51 from London Heathrow (LHR) to Dallas-Fort Worth (DFW). The program is designed to streamline connections by removing multiple processing steps for eligible travelers.
Previously, international arrivals at U.S. airports were required to:
- Proceed to the Customs and Border Protection (CBP) hall.
- Collect checked baggage and recheck it for the onward flight.
- Clear TSA security again before accessing the domestic gates.
With OSS, connecting passengers can clear passport control at the arrival gate itself. There is no requirement to claim and recheck bags or undergo TSA screening a second time.
Checked luggage is automatically transferred to the connecting flight, maintaining strict security protocols endorsed by CBP and TSA.
This operational model significantly cuts connection times, reportedly by more than 50%, enhancing the passenger experience while maintaining security integrity, View from the Wing reported.

Eligibility and Process Details
Currently, OSS is only available to passengers arriving on AA51 from London Heathrow who have a connecting flight beyond DFW. Travelers whose final destination is Dallas remain subject to the standard CBP arrivals process, including customs, immigration, and baggage recheck.
The steps for OSS-eligible passengers are:
- Clear passport control directly at the arrival gate at DFW.
- Bypass baggage claim, as checked luggage is automatically transferred.
- Proceed directly to the connecting gate without re-clearing TSA security.
American Airlines plans to expand OSS to additional flights in the future, though a specific timeline for expansion has not been disclosed.

U.S. Efforts to Streamline International Processing
This is not American Airlines’ first effort to optimize international travel logistics. In April, the carrier introduced international remote baggage screening (IRBS) for flights from Sydney (SYD) to Los Angeles (LAX).
While IRBS allows for checked bags to be automatically transferred beyond LAX, passengers must still clear immigration and undergo TSA screening — a distinction from the OSS model now trialed at DFW.
The OSS trial on the London–Dallas route is the first westbound implementation of this kind and marks a progressive shift in U.S. airport transit policy.
By reducing connection friction, American Airlines is enhancing DFW’s status as a major international hub and offering a competitive edge in the global travel network.
