If you are in any doubt that air travel is back to normal, take a look at the record breaking year many UK airports enjoyed in 2024.

Top of the list is Heathrow, which broke its previous record with 83.9 million passengers, an increase of 3.7% over 2019.

Heathrow has continued to break its own records with 6.3 million passengers in January and 5.7 million in February. (Obviously March 2025 will now be a little weak!) It predicts 84.2 million passengers for 2025, although that seems like a low ball.

What are the 25 busiest routes from Heathrow?

What are Heathrow’s busiest routes?

Last year, we published a list of routes from Heathrow with one million passengers or more. I thought it would be interesting to take another look at this with the updated 2024 figures.

As I understand it, Heathrow has more millionaire’ routes than any other airport; next-best is Dubai (DXB) with has, I’m told, 22 such routes.

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 – 3.2m
  • Dubai (DXB) – 2.5m
  • Doha (DOH) – 2m
  • Dublin (DUB) – 1.9m
  • Los Angeles (LAX) – 1.7m
  • Madrid (MAD) – 1.5m
  • Amsterdam (AMS) – 1.5m
  • Delhi (DEL) – 1.4m
  • Frankfurt (FRA) – 1.4m
  • Istanbul (IST) – 1.3m
What are the 25 busiest routes from Heathrow?
  • Munich (MUC) – 1.3m
  • Toronto (YYZ) – 1.2m
  • Hong Kong (HKG) – 1.2m
  • Singapore (SIN) – 1.2m
  • Abu Dhabi (AUH) – 1.2m
  • Zurich (ZRH) – 1.2m
  • Mumbai (BOM) – 1.2m
  • Edinburgh (EDI) – 1.1m
  • Chicago (ORD) – 1.1m
  • Paris (CDG) – 1.1m
  • Lisbon (LIS) – 1.1m
  • Miami (MIA) 1.1m
  • San Francisco (SFO) – 1.1m
  • Boston (BOS) – 1.1m
  • Geneva (GVA) – 1m

Together, the top 25 routes contribute 35.6 million passengers to Heathrow’s annual total – 42% of its total. The remaining 214 airports served from Heathrow make up the rest.

New York is the predictable winner. Newark, which made the list in 2023, is the only route not to have made it this year.

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.

Abu Dhabi and Miami are both new additions to this list. Heathrow now has five direct flights to Miami per day, including one on BA’s A380. Both Virgin Atlantic and American Airlines operate two each. Abu Dhabi, meanwhile, sees up to five daily flights (four from Etihad, one from BA) with at least two regularly on A380s.

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

  • Reney says:

    I’m surprised that HKG is 13th yet BA has dropped down to one flight a day.

    • Kowalski says:

      I believe Cathay Pacific run at least 5 times daily between Heathrow and Hong Kong

      • Guido says:

        As a BA gold card holder and one that has done quite a few of the LHR-HKG legs (most recently earlier this month), I cannot understand why anyone would choose to fly BA to HKG over Cathay, especially on their A350. Everything about the Cathay experience is just so much better. The lounges, the crew and the on board experience are all far superior to what BA has to offer.

    • BBbetter says:

      Other airlines can fly over Russia.

      • Ron says:

        Don’t think CX fly over Russia.

        • John says:

          They do on HK to US, but not on HK to Europe

          • Londonsteve says:

            Might be to do with the fact that the European competition also cannot (therefore the longer flight time is not a disadvantage) and they avoid hideously high Russian overflight costs by avoiding the country.

  • NorthernLass says:

    I think the morning departure from EWR has been binned, which might partly explain the drop in numbers.

    The fact that there’s only one U.K. regional airport in this list goes to show how BA has abandoned the country outside London!

    • BBbetter says:

      Doesn’t that show people prefer to fly non-BA from regional airports?
      For example AMS would be even higher on the list if all uk airports were included, thanks to KLM flying to a dozen regional airports?

      • NorthernLass says:

        No, it shows that BA is continuing to gut domestic services (apart from EDI, apparently).

    • Shaw Gaubie says:

      Blame Walsh. He started it. His reward was Director General of IATA. God help us,

  • Fennec says:

    What special relationship?! a fair few English folk seem to think England has a reciprocal one with the USA when it’s very much one sided; it’s sycophantic and sad.

    The only special relationship they have is with Canada and you can see how well they treat them..!

    • kevin86 says:

      I don’t know any English people who give a monkeys about a “special relationship”.

      • Londonsteve says:

        And anyone who did still believe in the ‘special relationship’ will have now woken up with a nasty hangover. Not only does the special relationship no longer exist (if the US ever really took it seriously, which is a moot point), the US is now a state hostile to the UK and the rest of Europe. I never thought I’d have the write this, but we need to forget about them for the forseeable future and in my case, that involves crossing them off my list of potential travel destinations. I’m not interested in ending up finding myself incarcerated for a month because I might have expressed opposition to the US administration on social media.

        • NorthernLass says:

          I think you’re conflating the US government with the country, its people and its history. And I hope you have no plans to visit China if you’re concerned about such things!

          • Londonsteve says:

            I’m not mixing up the government with the people, no. On the subject of the people owever, fully 50% voted for Trump which is a bad place to start, despite having witnessed his performance during his first administration. It does nothing to sell the people to me, I’m afraid.

            China is also crossed off my list, fret not.

      • Londonsteve says:

        It serves to illustrate their authoritarian hostility to anyone they perceive as ‘opposition’ that instead of just deporting someone on the next plane they don’t like the look of, they seek to imprison them to make an example of them as a way of silencing the critics. ‘Land of the free’, sure pal.

        • Andy in Cheshire says:

          It will be interesting to see how the number of flights to the US goes down given the politics

          • Londonsteve says:

            They might be filled with refugees from the US seeking to flee! Apparently, European academic institutions are already overwhelmed with applicants from the US.

          • Danny says:

            I doubt many US academics would be willing to accept the huge paycuts a move to Europe would require.

          • Londonsteve says:

            They might be forced to due to their political views. Also, the cost of living in Europe is on average half that of the US today. Lastly, academics are seldom motivated solely by financial matters. They’ll have originally been attracted by the prestige of many US institutions and their solid financial background to fund their research.

        • John says:

          My acquaintance had a one-way ticket Asia-US-Canada, and a Canadian visa which permitted him to work there. He was denied entry into the US because they didn’t believe he would take his onward flight to Canada. His mistake was to be nervous because of the tight connection time and say “I’ll definitely miss the flight if you don’t let me through quickly” or something like that.

          The US detained him for 3 days then sent him back to the Asian country where he flew from (all at the US taxpayer’s expense). As he had only been a tourist there, that Asian country refused to let him back in because of the US denial of entry stamp! But being far more sensible than the US, they allowed him to buy a new ticket to Canada.

          Note that this happened under the Obama administration. The recent news stories do not indicate a shift in policy (apart from the thing about anti-Trump views – but the US claims that the French scientist had classified information on his device).

          If Trump/Musk are serious about DOGE (which of course they aren’t really) they would of course do exactly what you say and just escort people to the onward flights they have already paid for, or immediately “self-deport” at their own expense.

  • Richie says:

    Interesting that LCY doesn’t have Madrid and Munich flights.

    • Tony says:

      LCY-MUC seems to be a proper start-stop job. I recall flying this with Lufthansa in a prop plane 20+ yrs ago, then did BA just a few years back.

  • Chris says:

    BA this Easter has only one LHR-MIA flight, I believe that I read that this is due to delays the delivery of RR engines and parts.

  • Ed says:

    I’m surprised HKG made it to the list even after Virgin dropped out and BA dropped down to one flight per day.

    Cathay Pacific run five times daily from Heathrow but from my experience these flights are rarely completely full either

    • Danny says:

      Cathay’s load factors on LHR to HKG and vv are very high. I know as much because Cathay crew find it a challenge to book staff travel on the Heathrow flights due to the load factors

    • John says:

      CX is not stupid. If they only had enough booked pax for 4 planes they would cancel the 5th flight. The fact that this rarely happens indicates that they do have enough pax for the flights they operate.

      The flow of pax is sometimes directional depending on time of year, so the flights to London may be not full but the inbounds to HK may be full, or vice versa. Flights may be profitable even if only the J cabin is full.

  • RogerWilco says:

    Regarding immigration practices on the Eurostar – it is what it is, sub-optimal, probably to pander to certain political goals.

    It could be different, though. Let’s take the Helsinki – St Petersburg train (you can’t anymore since the Russian invasion of Ukraine) also an EU-Schengen non-EU/non-Schengen route
    The Finnish border guards would start checking docs on the moving train from the last domestic stop until the border. Once done, the train moved on to Russia, where the Russian border guards would mount right after the border, collect passports and give them back stamped in before your destination (either Viipuri or St Pete)
    Going the opposite direction, the same – border guards came on already in St Pete, collected passports, returned them before the border. Customs agents walked through the moving train as well. Once across on the Finnish side, the Finns would come on the train and do the formalities (IIRC while at the border station but maybe on the moving train) No immigration control at either end.
    IIRC on the Finnish side we did 200km/h tops, on the Russian side 220-230 km/h or so.

    Could be done similarly on the Eurostar as well.

    • Londonsteve says:

      To the best of my knowledge, the only motivation for Eurostar controls being what they are is to stop people getting to UK soil and claiming asylum. I guess that the airlines check rights of entry to the UK at the boarding gate, whereas the sea routes/Eurotunnel and Eurostar do not. If they did, it would do without the need for having UK Border Force staff at the point of embarkation.
