American and Delta introduce ‘One Stop Security’ on some Heathrow flights

Anyone who has ever taken a connecting international flight to or from the US will know that the experience is woeful.

Unlike the UK, the US insists that all passengers – no matter whether you are staying in the US or not – get off the plane, clear immigration, re-check your bags and go through security again.

It’s a painful experience and one you’re unlikely to try again once you’ve had the misfortune of experiencing it.

AA and Delta introduce 'One Stop Security' on some Heathrow flights

Fortunately, they are starting to do something about it.

Under the ‘One Stop Security’ program, the US Transportation Security Administration (TSA) and Customs and Border Protection (CBP) are introducing seamless connections for some travellers.

For now, the new streamlined service is only available on flights from Heathrow to Dallas Fort Worth (on American Airlines) and Atlanta (on Delta Air Lines flights).

Instead of going through the palaver I described above, any connecting passengers will now clear US customs at the gate and be able to head straight to their connecting flight. You won’t need to recheck your baggage or clear security again.

According to American, this will cut connection times in half.

Rollout of One Stop Security is likely to be a long process. With just two routes offered for now, it will clearly be of limited benefit to most travellers – but if you’re lucky enough to be on one of those flights, your life just got easier.

    Is this actually new? I transited through Dallas on route to Colombia I was asked about how much cash I had but didn’t have to recollect my bag. I had a nightmare on the way back coming through Chicago. Where I did have to collect my bag and recheck. Non of the staff seemed to speak English either.

      DFW hasn’t needed to recheck bags if you are transiting international to international for a few years.

      This is different because you do CBP/immigration at the gate rather than going to the international arrivals area and they’ll do this for baggage for domestic transfers too.

      It seems to have started on 23 July.

      What’s new is that you don’t have to do security at DFW.

  • SammyJ says:

    Has it been confirmed that this includes UK-US flights with a domestic transfer in ATL/DFW as opposed to int-int? I’m thinking of the Orlando Facebook brigade who often have very little experience of US travel but often transit in ATL, and pre/plan every detail down to the inflight movies and Disney-declared snack boxes…

    • John says:

      For DFW, it’s only AA flights from LHR (not UK) that are in scope, and for ATL it is only DL flights from LHR and ICN.

      It doesn’t matter whether your onward flight is US domestic or not, as there is no segregation between domestic and international departure gates

  • BJ says:

    Connecting at LHT to/from anywhere, not just the USA, is a horrible experience. By far the worst of any major airport I’ve encountered. It’s so bad I have only done it twice in the last five years coming back from HKG to bemefit from liw fees.

    I am so old that I remember the notorious LAX transfer scam in the era before suitcases had wheels. After shuffling for up to an hour in a queue for immigration and then customs at LAX you had to schlep your unwheeled suitcase, which had been tagged to its ultimate destination at check-in in London, to a conveyor belt for it to transferred to your next flight. The porters at LAX ensured that no trollies were available. One of them in exchange for a US dollar would take your bag for you to the conveyor. Hot, sweaty and tired, you complied.
    Once I had to meet a naïve but very rich client in Denver. He was unused to the USA so I explained to him in detail that if he didn’t give the porter a dollar his luggage would unquestionably end up in the American equivalent of Timbuctoo. He arrived in Denver, but his luggage did not. “I can’t understand it”, he said. “I didn’t have a dollar, so I gave him two pound notes”. We got his luggage three days later.

    I’ve done intl-intl connections twice in the US, the first was a fantastic deal looking back: London to NZ & Australia with United (via DEN/SFO and SFO/ORD) in premium economy for £1600 in December 2022!
    A slightly tight 2h connection on the way back where this system would have been nice!

    The second was just last year when I was rerouted back from Asia via DFW to London on AA.
    They put a red tag on my bag so I didn’t need to recheck it after baggage claim & CBP, but of course did need to go through TSA again.

    Connecting to domestic flights in the US with all this rigmarole is similarly painful having to re-clear security.

    Generally, I’ve found the MPC app to be brilliant for speeding up entry from my (small) sample size but is probably pot luck…

    It would be interesting to see how this works in practice though as the jetbridges aren’t exactly spacious to be doing immigration checks, presumably they just let you into the terminal via the normal arrivals door instead of sending you up/down an escalator to the international corridors.

    Is there something specific about Dallas and Atlanta physically that makes them ideal candidates?

  • budva says:

    Getting GE is a really worthwhile investment. You will get your TSA Precheck included. Immigration was a doddle. I was not sure what to do the first time I used it so I walked towards a booth and without doing anything it recognised me and printed out a receipt, showed it to the CBP guy, “Welcome to America”. The only thing I would like is to be able to have one of the GE cards, which hugely speeds up crossing the USA-Mexico border
