While American Airlines flies many point-to-point passengers on its flights to London, a significant number of travelers also connect to other destinations out of the UK and the US. The airline has now partnered with the governments of both countries to make the traveling experience of transit passengers out of London traveling from Dallas a little easier as far as security clearance is concerned.
New security program
If you’re booked on an American Airlines
flight between Dallas Fort Worth International Airport (DFW) and London Heathrow Airport
(LHR) with a flight connection to another destination, then your travel experience will now be a little smoother.
The US Transportation Security Administration (TSA) and the UK Department for Transport (DfT) have partnered with American Airlines and announced a new pilot program called One Stop Security (OSS).
This initiative aims to provide easier connections for passengers traveling from Dallas to international (non-UK) destinations through London. According to the official announcement, passengers connecting in Terminals 3 or 5 are not required to go through security screening a second time.

This would translate into quicker airport transit and not having to worry about re-screening and re-checking bags. American was one of the founding partners of this program and collaborated with the governments of both countries to launch it on February 4. Nate Gatten, Chief Government Affairs Officer for American, commented,
“American Airlines is thrilled to be working with the U.S. and U.K. governments to roll out a first-of-its-kind security agreement that will provide our customers a more seamless and secure flying experience. This partnership simplifies international air travel for our customers, and we look forward to opportunities to expand it to more airports, including from LHR to DFW, in the future.”
Significant traffic to London
American Airlines carries millions of passengers to Europe from its big hubs in the United States. According to data from the US Department of Transportation, in the 12 months ending November 2024, the carrier flew 8.4 million passengers to Europe, behind only Delta and United Airlines.
Unsurprisingly, London Heathrow was its biggest destination, with seven routes to this airport carrying more than 250,000 passengers. Of course, the biggest route was from its primary hub of Dallas/Fort Worth, with 645,000 roundtrip passengers.

Other big routes included New York JFK-London Heathrow (573,000), Charlotte-London Heathrow (487,000), Chicago O’Hare-London Heathrow (471,000), Los Angeles-London Heathrow (414,000), Miami-London Heathrow (339,000), and Philadelphia-London Heathrow (257,000).
In fact, data also reveals that 42% of Dallas/Fort Worth-London Heathrow passengers had a flight connection to a third destination, either in Dallas, London, or both, with Cancun-Dallas/Fort Worth-London being the most popular connection. Simple Flying’s route analyst James Pearson examined this in detail in the article below.

They include four routes that began in 2024.
Extensive network to Europe
American Airlines is one of the three big legacy carriers that offer an extensive network of flights between the US and Europe. Last year, the carrier announced several new routes to Europe for the 2025 summer season.
These included flights from Philadelphia to Edinburgh, Scotland; Charlotte, North Carolina to Athens, Greece; Miami to Rome; and Philadelphia to Milan.
However, it was also recently reported that the carrier will
suspend three European routes
and reduce frequency on others because of delivery delays of its widebody planes from Boeing. The routes that have been affected are:
- Miami (MIA) to Paris (CDG)
- Dallas (DFW) to Frankfurt (FRA)
- New York (JFK) to Madrid (MAD)

The flight between Miami International Airport (MIA) and Paris Charles de Gaulle International Airport (CDG) was initially suspended in May 2025, but that has now been extended to June and July as well.
The airline stated that it is adjusting service on certain routes in the summer of 2025 to ensure it is able to re-accommodate customers on affected flights. The airline will also reduce flight frequency to London from New York as well as from Dallas, from where it will reduce from five daily flights to four in May 2025.
