What are the 24 routes from Heathrow airport with over 1 million passengers annually?

If you are in any doubt that air travel is back to normal, take a look at Heathrow’s record-breaking December 2023 performance.

With 6.6 million passengers, Heathrow is calling it the biggest December ever, beating pre-covid years. It’s not alone – Stansted and Manchester Airport have also reported a record-beating December with just over 2 million passengers served each.

The Heathrow numbers suggest that 2024 will comfortably beat the airport’s pre-covid record of 80.9 million passengers from 2019.

What are the 24 busiest routes from Heathrow?

In fact, it will only take 1.7 million more passengers than 2023 to break that record – an increase of just over 2%.

In 2023, 79.2 million people passed through the airport, effortlessly sailing past the forecast of 67.2 million that it made at the end of 2022 when negotiating a fee increase with the CAA.

With a new CEO in place – and the CAA having finalised its ruling for the charges Heathrow can levy on passengers – it’s back to business as usual. The airport will want to keep its new Saudi Arabian shareholder happy and is predicting 81.4 million passengers this year.

What are Heathrow’s busiest routes?

Quietly tucked away at the bottom of the press release was a list of 24 routes with 1 million or more passengers from Heathrow. Combined, they contribute a third or more to Heathrow’s overall passenger numbers.

These are based on where the initial flight lands and do not account for connecting itineraries, which is why Dubai and Doha rank so highly. Anyone flying from Heathrow to Singapore on Emirates is counted as travelling to Dubai.

Descending from highest passenger volume (remember that all serve 1m+ Heathrow passengers per year):

  • New York (JFK)
  • Dubai (DXB)
  • Doha (DOH)
  • Dublin (DUB)
  • Los Angeles (LAX)
  • Madrid (MAD)
  • Amsterdam (AMS)
  • Frankfurt (FRA)
  • Delhi (DEL)
  • Istanbul (IST)
  • Munich (MUC)
  • Hong Kong (HKG)
What are the 24 busiest routes from Heathrow?
  • Toronto (YYZ)
  • Singapore (SIN)
  • Zurich (ZRH)
  • Mumbai (BOM)
  • Chicago (ORD)
  • San Francisco (SFO)
  • Paris (CDG)
  • New York (EWR)
  • Edinburgh (EDI)
  • Lisbon (LIS)
  • Boston (BOS)
  • Geneva (GVA)

New York is the predictable winner and actually appears on the list twice – once for JFK (in top spot) and once for Newark.

The London to New York corridor is one of the most lucrative in the world. In 2018, Heathrow to New York JFK became the first billion-dollar route in the world for a single airline – British Airways. Add in other airlines and airports (Gatwick, Newark) and you can see how important the special relationship is to the UK.

There are a few other interesting tidbits. For example, fewer passengers travel directly to Singapore than either Hong Kong or Toronto, which surprises me.

You can clearly see the ‘Eurostar effect’ when you compare Amsterdam and Paris, with Amsterdam a full 13 spots ahead.

Boston and Geneva are both new additions to this list, having broken a million passengers for the first time last year. London to Boston has seen a number of additional flights in the past year or so, with JetBlue launching a daily service and incumbent airlines such as United responding defensively. United cut its Boston flight in October, so we may see Boston slip off this list again in 2024.

  • BajiNahid says:

    wonder why the EDI-LGW was culled and that was the end of that. Surely would have diluted the heathrow numbers.

    We need a BA LGW service as the other alternative LON airport and not just heathrow or city.

    Also EDI has been very up and coming and many tourists are flocking to visit!

    • newsmike says:

      MAN-LGW was also culled, significant loss of connectivity on the leisure side

    • Andrew. says:

      A couple more BA GLA to LGW flights a day would be equally helpful. For many people in the central belt, it doesn’t really make much difference whether they go East or West to get to the airport.

      Are the figures for 2007 available on LHR-EDI? I’m curious what the difference is in loadings from before the financial crisis when between RBS Group and HBOS could probably have filled the first BA flight and the equivalent BMI flight every morning on the route from the Capital to LHR. BA (who operated a 767 on the domestic diagram) & BMI operating around 20 flights a day between them back then, and down to 11 a day on lower capacity equipment now, the passenger numbers must be lower.

      • Stu_N says:

        “For many people in the central belt, it doesn’t really make much difference whether they go East or West to get to the airport.” Disagree – Edinburgh is easier for anyone east of Baillieston by road as you don’t have to go through or round the centre of Glasgow and the public transport links to Glasgow Airport are woeful.

        GLA is now very much in the shadow of EDI, it had 6.5m passengers vs 11.3m for EDI last year and the facilities and general upkeep of the place is miles behind Edinburgh IMO.

        The 767 effect is less than you’d maybe think too – the short haul 767s were 237 seats and an A321 is now 220 seats.

      • CJD says:

        RBS Group (now NatWest) will still account for a lot of EDI-LHR flights because of the location of Gogarburn. EDI-London is the main internal flight journey which the group is trying to encourage staff off and onto trains instead.

      • CJD says:

        I’d argue that Edinburgh is probably more convenient for anyone who lives east of Glasgow. The road connections are much better than side of Glasgow and it avoids having to travel through central Glasgow on the M8.

    • Lesley says:

      Totally agree, it’s a real pain having to go to LHR and then get a bus to LGW for your next onward flight, having to do this next week for trip to Costa Rica.

      • Roy says:

        It’s a shame there was no traction behind the proposal to have a high-speed rail link connecting LHR and LGW so that they could function as a single hub. I guess Heathrow inevitably was not going to support a proposal that would make LGW more attractive…

        • Tom says:

          Last weekend we travelled LHR T5 > Elizabeth Line > Farringdon > Thames Link > LGW for slightly more than the coach, slightly longer, but no M25 risks\stress

  • e14 says:

    Amsterdam is apparently a good place to do back to backs for EU’s

    Don’t think Sofía will make 1m pax, but it might given the party buses BA is running

  • Ian says:

    Can’t believe that Miami isn’t in the list.

    Surely more fly there annually than some of the routes?

    • NicktheGreek says:

      Must be close, but looking at some others on the list there’s a fair few flights, some surprisingly so.
      Toronto – 4-6 flights per day
      Boston – 7-8 flights per day
      Lisbon – 12ish flights per day
      Geneva – 12ish flights per day.

      Miami 5-6 flights per day

    • Mark says:

      Miami has just been reduced from 2-1 flight a day.

    • HALTraffic says:

      Miami was very close, in all likelihood it will make it back onto the list in 2024.

  • Subhajyoti says:

    Several India bound passengers take indirect flights from Heathrow (ie via Dubai, Doha, Amsterdam etc) … Delhi & Mumbai could have gone further up the list if this is taken into account

    • Justin says:

      Non-sense. It’s the same for all destinations, and I doubt Doha would be on the list at all if you removed connecting passengers!

      • BBbetter says:

        True, but its changing. With Air India getting better and Vistara expanding, there will be some shift away from ME3 to Delhi & Mumbai.

  • Richie says:

    Munich is higher than I thought it would be.

    • ADS says:

      I came here to say that !

      Also, is it the only European airport on the list that isn’t a full blown hub?

      • Lynx says:

        Munich is a hub for LH and is also a popular leisure destination in its own right.

  • Phillip says:

    I too would have expected Singapore to be higher up but thinking about it, despite SQ’s frequencies, BA is still operating smaller aircraft to what it did pre pandemic.

    • BBbetter says:

      I wonder if the frequency to HKG is actually higher than SIN.

      • Phillip says:

        I would expect HKG to pick up too – again, BA is barely operating 2 flights at the moment both on 787s but HKG was a lot later in lifting restrictions compared to SIN. I guess SIN is also far enough that more people are likely to fly indirect compared to DOH and DXB. Interesting that AUH is nowhere to be seen!

        • John says:

          CX has 4.5 flights daily and would like to restart LGW if they manage to sort out the staffing problems. BA has had 2 daily since around 2007 when the 3rd flight was dropped.

          Anyone who wanted to go to HK after restrictions ended has gone by now. I suspect there is a permanent lower demand and HKG is also affected by the route diversion whereas SIN isn’t really, which may be part of why they are using the A380 elsewhere

    • Alex G says:

      BA is putting an A380 on one of the daily SIN flights in March.

  • TimM says:

    There is an element of self-fulfilling prophecy. We can only travel on the routes that exist and the well-served ones are more popular for convenience.

    Clearly there are more customers available to travel between two big cities so the airlines have a slam dunk there.

    I would like to see the same figures adjusted by population of the origin + destination.

  • Sarah says:

    I’m surprised that Dublin is so high – BA have really cut back on their flights to there and handed a lot of the business to Aer Lingus, you’d think they’d want to have kept more for themselves.

    • Rich says:

      ? Both IAG owned. The stat is for LHR routes not BA routes so supply switches between carriers are irrelevant.

    • john says:

      Running Aer Lingus instead of BA could be a way to increase capacity since they don’t operate a business class cabin on the route so can sell all the seats where as BA have to block middle in club.

    • BA Flyer IHG Stayer says:

      These figures are for all airlines operating a route not just BA flights.

    • ADS says:

      And in addition to all the LHR-DUB flights there are probably more flights from other London airports to DUB than any other European airport.

      Looking at next Monday, currently available:

      LCY 7 [BA]
      LGW 12 [EI/FR]
      STN 8 [FR]
      LTN 3 [FR]

    • Michael says:

      As well as BA’s traffic, Aer Lingus runs up to 14 daily rotations to LHR from DUB in the peak summer schedule, a mix of A320s and A321s. Some of the A321s are their long haul config but the short haul ones are pretty densely configured with only the first row with blocked middle seats (Aer Space). Some of BAs 777s used on LHR-JFK only carry 235 passengers so not that much more than an A321.

      At one stage in the past LON-DUB was one of the busiest city pairs in the world.
