Making a connection at London’s Heathrow Airport (LHR) can be a drag—especially after a long flight from the U.S. But a new pilot program called One Stop Security is about to make things smoother for some travelers.
Passengers flying from Dallas Fort Worth International Airport (DFW) and Hartsfield-Jackson Atlanta International Airport (ATL) can skip the tedious security recheck when connecting through Heathrow's Terminal 3 or Terminal 5.
American Airlines, in collaboration with British Airways, launched the trial on February 4. Delta Air Lines, British Airways and Virgin Atlantic are also participating, offering the same benefit to travelers from ATL. This is possible thanks to aligned security standards between the U.S. Transportation Security Administration (TSA) and the U.K.'s Department for Transport.
How One-Stop Security works
Typically, passengers connecting through LHR need to deplane and navigate back through security—often after shuttling between terminals. With One Stop Security, travelers from participating airlines at DFW and ATL can head straight to their connecting gate, no extra screening required.
This streamlined process can be a game changer for those navigating the notoriously hectic Heathrow, especially on busy travel days when security lines can feel endless. The program aims to save time, reduce stress, and give travelers a chance to actually enjoy their layovers.
There is a catch, however. This is just a trial. If you're not flying from DFW or ATL, you'll still need to clear security in London. But with these airports being the two busiest airports in the U.S., this program already has the potential to impact thousands of travelers.
What's next for One-Stop Security
There’s hope that this trial's success could inspire similar efforts at other U.S. airports. The TSA has been exploring the idea of One-Stop Security for international travelers coming into the U.S., which could further streamline global connections.
For now, if you're flying through DFW or ATL to London, enjoy the smoother ride—and maybe an extra coffee in the airport lounge while everyone else lines up for security.
