Along with New York’s JFK, London’s Heathrow is one of the airports I think of as a “home” airport, so this one was always going to be slightly different from the earlier entries in this series.
At Singapore and Nadi, I was documenting an arrival process in a place I was visiting. Melbourne added the complication of arriving on a full long-haul flight and waiting for a checked bag. At Heathrow, I know exactly where I’m going. I know which passport lane I can use, I know the route through Terminal 2, and once I’m landside I know how I’m getting home.
But familiarity doesn’t make the distances any shorter. Heathrow Terminal 2 can involve a surprisingly long walk from aircraft to immigration, and arriving landside isn’t necessarily the end of the useful journey. For many passengers, the next question is how quickly they can actually get onto a train towards London.
So this time I kept the clock running.
The rules
As with the previous Gateside to Curbside tests:
The stopwatch starts when I step off the aircraft.
I walk at my normal pace.
I don’t overtake people simply to improve the time.
I slow for photographs as I naturally would.
I’m traveling with a checked suitcase.
The Gateside to Curbside clock stops when I reach the public arrivals area after immigration, baggage reclaim and customs.
For Heathrow, I also continued recording the journey to the Elizabeth line and Paddington.

Gateside to curbside: 21 minutes.
From wheels touching the runway to public arrivals was 39 minutes. From stepping off the aircraft to Paddington was 61 minutes.
5:15 am: Touchdown
The wheels touched the runway at 5:15 am after the overnight flight into Heathrow. Consistent with the other cases in the series, however, touchdown isn’t where the Gateside to Curbside clock starts. There is still taxiing, getting onto stand and waiting to leave the aircraft. This time that took 18 minutes.
At 5:33 am, I stepped off the aircraft and started the timer.

Stepping off the aircraft at Heathrow Terminal 2 at 5:33 am. This is where my Gateside to Curbside clock started.
5:33 am: The Heathrow walk begins
The first few minutes were almost entirely about covering the long distance towards the immigration hall.

The first part of the Heathrow arrival involves covering some distance.
Terminal 2 at Heathrow, like most Heathrow terminals, is not a place where leaving the aircraft means you’re almost at immigration. From the jet bridge, the route continues through a succession of corridors, moving walkways, escalators and junctions, all following signs for Arrivals and Baggage Reclaim.

Still following the signs for Terminal 2 Arrivals and Baggage Reclaim.
At 5:35 I was still walking. At 5:37 I was still walking. At 5:40 I was descending towards the arrivals processing area. The signs were clear and the terminal was extremely quiet at that hour, but you do have to cover a significant distance.
5:41 am: UK Border
I reached the UK Border area at 5:41 am, eight minutes after stepping off the aircraft. And then, a traveler’s dream after an overnight flight:

The UK Border area was almost completely empty when I reached it at 5:41 am.
The eGate area was virtually empty. There was no meaningful queue, and by 5:43 am I was through.
For this particular arrival, immigration wasn’t the bottleneck at all. Getting from the aircraft to immigration took much longer than getting through immigration itself.
That obviously won’t be everyone’s experience at Heathrow. Passport eligibility, eGate operation and the number of flights arriving at the same time can all change the equation. But on this early-morning arrival, the UK Border was remarkably quick.
5:44 am: Baggage reclaim

At 5:43 am, ours was the first and so far only arriving flight shown on the baggage reclaim screens.
Less than two minutes later I reached Belt 10. The first round of bags was already circulating when I arrived, which initially looked promising. However, my suitcase wasn’t among them.

I reached Belt 10 at 5:44 am. The first batch of bags was already circulating.
At 5:50 am, a second round of bags finally began arriving.

The second batch of luggage finally started coming onto the belt at 5:50 am.
My familiar blue suitcase was among that batch and appeared on the belt at 5:53 am. A few seconds later it was off the carousel and I was moving again.

My bag appeared at 5:53 am, nine minutes after I reached the carousel.
So baggage added nine minutes from the time I reached the belt until I had my suitcase. That isn’t particularly dramatic for a long-haul arrival, but it was easily the biggest processing delay of the morning. Immigration had taken almost no time; baggage was where I actually had to wait.
5:54 am: Landside
There was no meaningful customs delay, and at 5:54 am I entered the public arrivals area. Stop the clock.

Landside at 5:54 am, 21 minutes after stepping off the aircraft. The Gateside to Curbside experiment was complete.
21 minutes from stepping off the aircraft to completing the Heathrow arrival process with a checked bag.
That puts Heathrow remarkably close to Melbourne on this particular measure. More importantly, the composition of the time was different. At Heathrow, the long walk from the aircraft and the wait for baggage accounted for most of the journey. Immigration itself barely registered.
This is also the point at which arriving passengers start making different journeys. You might head for the taxi rank, order an Uber, take the Heathrow Express or continue towards the Underground and Elizabeth line. For the purposes of Gateside to Curbside, those choices happen after the experiment is over.
After the experiment: Getting into London
For me, traveling alone and heading into central London, there wasn’t much of a decision to make. I took the Elizabeth line.

From here, the journey continued. The Elizabeth line and Heathrow Express are reached via the lifts to Level -1.
If you’re comfortable with London’s public transport and you’re staying somewhere reasonably central, I find it difficult to make the case for paying for a car when traveling alone. Add another couple of people and the economics start to change. A price-insensitive expense account changes them further, and there will always be destinations or amounts of luggage where door-to-door transport wins on convenience. But for a solo traveler heading into central London with a single suitcase, the Elizabeth line is very difficult to beat.
So although the Gateside to Curbside experiment had finished, I kept taking photos and timestamps to see how long the rest of the journey would take.
How long from Heathrow arrivals to the Elizabeth line?
I was already following the signs for trains by 5:55 am. From Terminal 2 arrivals, the route to the rail station involves another small journey: down to the subway level, along the underground passage, through the rail concourse and eventually to the platforms used by the Elizabeth line and Heathrow Express.
I was in the lift at 5:56, walking through the subway at 5:58, and at the rail concourse by 5:59. At 6:02 am I was through the rail gates.
The Elizabeth line train arrived at 6:04 am and I was onboard at 6:05 am.

The Elizabeth line train arrived at 6:04 am, ten minutes after I entered public arrivals.
That means it took only 11 minutes from entering Heathrow’s public arrivals area to sitting on an Elizabeth line train.

Onboard at 6:05 am: 11 minutes from public arrivals to an Elizabeth line seat.
Or, measured from the aircraft door, I had gone from stepping off a long-haul flight to sitting on a train for central London in 32 minutes, including immigration and collecting a checked suitcase.
6:34 am: Paddington
Just under half an hour later, the train pulled into Paddington. At 6:34 am, I was standing on the platform with my suitcase, ready to transfer to the Underground for the final part of the journey home. That produces another useful Heathrow number:
Aircraft door to Paddington: 1 hour 1 minute.
Measured from touchdown rather than the aircraft door, it was 1 hour 19 minutes from wheels hitting the runway to standing at Paddington.
Of course, Paddington wasn’t my final destination. That’s an important distinction in London. Reaching central London and reaching your hotel, home or meeting can be two quite different things. I still had a short Underground journey ahead of me.
But as a benchmark for someone wondering how quickly an early-morning Heathrow arrival can turn into actually being in central London, it should be useful.

Paddington at 6:34 am, 61 minutes after stepping off the aircraft at Heathrow.
Where did the time go?
The Heathrow journey breaks down rather neatly:
Stage | Time |
|---|---|
Touchdown to aircraft door | 18 min |
Aircraft door to UK Border | 8 min |
UK Border processing | 2 min |
Border to baggage reclaim | 1 min |
Waiting for checked bag | 9 min |
Bag to public arrivals | 1 min |
The airport itself performed extremely well. The most striking part wasn’t the speed of immigration. It was how much of the Heathrow arrival consists of covering distance. Eight minutes to reach the border, followed by another 11 minutes from landside to sitting on the Elizabeth line, means 19 minutes of the journey was spent navigating Heathrow rather than waiting for anyone to process me.
Final thoughts
A 5:15 am arrival is obviously favorable. Heathrow was quiet, the eGates were empty and there was no customs queue. A busy morning arrival bank can, and I can assure you, often does, produce a very different result.
But that’s part of the point of these tests. They’re not estimates of how long Heathrow will always take. They’re records of what actually happened on a particular arrival, with the conditions and delays documented along the way.
On this one, Heathrow took 21 minutes from aircraft door to public arrivals with a checked bag. Eleven minutes later I was aboard the Elizabeth line, and 61 minutes after stepping off the aircraft I was at Paddington.
For an airport that has never exactly been famous for being small, nor particularly efficient, that’s not a bad result.
Series methodology: Gateside to Curbside records the actual time from stepping off the aircraft until reaching the public arrivals area after completing immigration, baggage reclaim and customs. I travel at my normal pace, don’t optimize the route for the test, and slow to take photos naturally along the way.
