American Airlines & Delta, Bringing One Stop Security To The US?

Looking to turn your next European → U.S. connection into a breeze? American Airlines just flipped the script on airport layovers with its new One Stop Security pilot. Here's why smart travelers are all ears.
✈️ What’s the Deal with One Stop Security (OSS)?
- American Airlines is the first U.S. carrier to pilot One Stop Security in partnership with TSA, CBP, and the U.K. Department for Transport on flights from London Heathrow (LHR) to Dallas/Fort Worth (DFW). Delta following in AA's footsteps with a similar partnership that just launched July 30th.
- OSS lets you skip the usual arrival foolishness: Rather than re-screening and baggage reprocessing upon arrival, qualifying passengers clear customs and TSA at London Heathrow (LHR) so when you land in the U.S., you can walk straight to your next gate. Checked bags make the trip for you.
Initially available on:
- American Airlines: Flight from LHR → Dallas/Fort Worth (DFW)
- Delta Air Lines: Flight from LHR → Atlanta (ATL)
According to travel experts, connection times are sliced by about 50% with American and 40% with Delta, depending on details.
Who Gets to Ride This Shortcut?
Eligibility is not universal. To use OSS, you must meet specific criteria:
- Be booked on the qualifying LHR → DFW or LHR → ATL itinerary.
- Flying with Delta: enroll in Global Entry or use the CBP Mobile Passport Control app (U.S. citizens or permanent residents only).
- Flying with American is limited at launch and rolled out by invitation via eligible ticket notifications.
So, families, casual cash flyers, or international passport travelers? You might still wait in TSA lines like the rest of us.
🧠 How It Works, Step by Step
- Fly from LHR to DFW/ATL on a participating American/Delta itinerary.
- At Heathrow, you're screened by TSA/CBP BEFORE boarding.
- Your bag is checked through to the final destination.
- In DFW or ATL, you land, walk off, dash to your next gate—no queues, no re-screening.
- That means no customs lines, no reclaiming bags, no security checkpoint reruns. Just straight‑to‑gate bliss.
Why This Actually Matters
✅ Time saved
Cutting connection steps in half can mean making flights you’d have missed—and less stress overall.
✅ Pressure off big hubs
DFW and ATL move thousands of connecting passengers a day. OSS frees up lines, reducing crowd backups and baggage chaos.
✅ No compromise on security
Instead of skipping safety, the shift happens earlier. Heathrow’s screening standards must match U.S. benchmarks and will be audited regularly.
✅ Bigger picture: U.S. travel gets modern
With global events like the 2026 World Cup and 2028 Olympics on the horizon, smoother transit strengthens U.S. airports’ competitive edge. OSS is part of a bigger tech pivot toward biometric identity and unified digital credentials.
Things That Still Suck (Because No System Is Perfect)
- For now only American & Delta are running this at DFW & ATL respectively.
- Deltas LHR to Atlanta, requires Global Entry or Mobile Passport.
- You must fit eligibility boxes. That excludes many travelers.
- It only applies to specific itineraries right now.
- Scaling to other airports (like Miami, Charlotte, O’Hare) is in the works, but hasn’t happened yet.
🧳 Travel Tips from Your Points-Savvy Friend
- Book LHR‑DFW/ATL on American/Delta when you want tight but worry-free connections.
- Make sure all legs are on one ticket: same-carrier or partnered fare gives you access to OSS.
- Keep an eye out, OSS might make its way to other American/Delta hubs like Miami, Charlotte, Chicago‑O’Hare in the coming months.
- Not flying through LHR‑DFW? Yeah, this one’s not for you. Yet.
🤹 The Big Picture
American Airlines, TSA, CBP, and DfT teamed up to reimagine security lines the same way your bank reimagined paper statements—painful, redundant, and a serious waste of time. OSS is the future of layovers, secure, streamlined, and smart.
Want to predict if OSS will pop up at your favorite U.S. airport? Look for carriers investing in biometric lanes and destination airports building better tech coordination. That's where this is heading.
