How to get a discount on Heathrow Express train tickets (2023 edition)

Links on Head for Points may support the site by paying a commission.  See here for all partner links.

It’s been a while since we last looked at the different ways of finding a Heathrow Express discount.

To celebrate the 25th anniversary of the service – we’re going to the birthday party next week! – I thought it was worth an update even if you’re not planning a trip at the moment.

You can book your tickets via the Heathrow Express website here.

‘Secret’ discounts are nearly, but not quite, dead

For many years, airlines opearating at Heathrow used to offer discounts on Heathrow Express tickets to passengers who booked via their websites. This is no longer possible.

The only offer I know of is in association with Mastercard.

The link for your discounted Heathrow Express ticket is hereIt is only valid for selected Mastercard cardholders. You need to try to register your Mastercard to see if it is accepted or not.

You save 12% on full fare standard and First Class tickets.

Remember that children travel FREE

Children under 15 travel for free on Heathrow Express.

This makes a substantial difference to the maths when you compare the train to a taxi.

Make serious savings by booking in advance

A range of Advanced Purchase tickets is available.  If you can plan ahead you can make big savings.

You can see the full list of prices here.

Tickets can be as cheap as £5.50 one way.  There is a yield management system in place, so if you book late or for a busy day (tickets are valid for a certain day, not a certain train) you will pay more.

Combine that with the fact that children under 15 are free, and a family of four could get to Heathrow for as little as £11. It could be even less with a Railcard.

Discounts for two or more people travelling

Heathrow Express has a special offer for two people travelling together – £55.50 return in Standard Class.  Full details are here.  You need to use promotion code DUOSAVER when you book.

If you are travelling in a group of three or more adults, see a deal for that here which saves 33% using Heathrow Express discount code 3RDOFF.

Heathrow Express discount

Earn Avios points or Heathrow Rewards points when you book

You are able to collect Heathrow Rewards points on Heathrow Express tickets booked online.   This works on both the main website and the Heathrow Express app.

You earn 1 Heathrow Rewards point per £1 spent.  Premium tier members of Heathrow Rewards earn 2 points per £1.  They can be redeemed 1:1 for Avios, Virgin Points, Emirates Skywards miles, Heathrow shopping vouchers and various other bits and pieces.

You can also collect Avios with your Heathrow Express tickets as this article explains.  This is a far more generous offer than the Heathrow Rewards one because you earn 5 Avios points per £1 spent (see ba.com here).

There is a snag, of course. You need to visit www.heathrowexpress.com/avios to book.  This site does not allow you to mix a promotional code with your booking, nor can you book Advanced Purchase tickets.

Using a railcard on Heathrow Express

Don’t forget that if you have a railcard (Network Railcard, 16-25 Railcard, TfL Annual Gold Card, Senior Railcard etc) then you can also get a discount – my Mum gets 34% off with her Senior Railcard.

Details of how to claim a Railcard discount are on this page of the Heathrow Express site.

Big discounts if you work for an airline

You save 75% on full-fare Express Saver and Business First tickets if you work at Heathrow – see here and scroll to the bottom.  This discount also applies to employees of airlines that operate out of Heathrow who have a valid airline photo ID card.

This means that if, for example, you work for British Airways at Gatwick, you are still entitled to 75% off your Heathrow Express ticket.  An easyJet employee would not as easyJet does not fly from Heathrow.

A free upgrade if you are Star Alliance Gold

You are able to upgrade your standard class ticket to First Class if you have a Star Alliance Gold card from any of their member airlines.  Simply sit in the First Class carriage and show your Gold card to the conductor.

The website for the offer is here.  Note that whilst the website says that you needed to have a ‘full fare’ Heathrow Express ticket, this is never imposed.

A free upgrade if you are British Airways Gold Guest List

The least known benefit of being a British Airways Gold Guest List member is a free First Class upgrade on Heathrow Express. This is also valid for one person travelling with you.

As ba.com explains, simply sit in First Class and show your Gold Guest List card and your standard class ticket to the conductor.

A standard British Airways Executive Club Gold card will NOT work – there is a small ‘GL’ in the corner of Gold Guest List membership cards.

Don’t forget the Elizabeth Line

If you don’t want to take the Heathrow Express at all, the slightly slower Elizabeth Line service also stops at Paddington, Heathrow Terminals 2-3, Terminal 4 and Terminal 5.

If you’ve not taken the Elizabeth Line to Heathrow in recent weeks, you might not know that a faster timetable was introduced in May.

Elizabeth Line fares are included in the daily fare cap for all your tube, tram, DLR, bus, overground and National Rail travel in London so you will never pay more than £14.90 for Zones 1-6 (which includes Heathrow).

If you have a London travelcard, for Zones 1 to 6, taking the Elizabeth Line will cost you nothing extra. If you have a travelcard for fewer zones, you only pay the difference between zone 6 and the outermost zone on your travelcard.

And, of course, there are the tube and indeed bus options. Both are cheaper, but the tube does lack the comfort and space of the trains – the Heathrow Express is, in my view, the ‘poshest’ train service in the country. In many ways, it depends where you are starting from as to whether going via Paddington is convenient.

    Don’t forget the advance purchase price stacks with both a railcard discount and “kids go free” offers. Our family of four is heading to Heathrow for a total of £7.30 each way.

  • Antonio says:

    If you work for the railway, you get 75% off standard class tickets

  • Charlie says:

    Elizabeth Line is substantially cheaper too if you do not need to go through Zone 1 by changing at Ealing Broadway (and can also be much faster if you live in west London). This opens up places like Earls Court, Notting Hill Gate etc for the Zone 2-6 fare only.

    Only people taking HEX these days seem to be tourists who got mugged in the duty free store in Arrivals, or who booked far ahead and got lucky with BA by getting an on-time arrival into LHR so make the train connection work.

    • Andrew J says:

      Absolutely – should be renamed the Tourist Express. Anyone in the know uses alternative transport.

      Although on your point around train time connections – advance tickets only require you to specify the date, not the time.

      • Alex says:

        Not really, an advance ticket on the Heathrow Express can quite easily be cheaper and quicker than the Lizzy Line

        • lumma says:

          But you’re still only at Paddington mainline station, which is unlikely to be most people’s final destination and it’s a lengthy and confusing interchange to the separate tube stations AND you have to pay an extra zone 1 journey on top of the HEX ticket.

          If you take the Elizabeth line and do more journeys the same day, you’ll hit the Z1-6 cap pretty quickly too

          • ClubSmed says:

            I fly down at least once a month and my final destination is Paddington. That is where the hotel I use is, and it is just a short walk from there to the office in Marylebone.
            I use HEx rather than Elizabeth Line as I know my schedule well in advance so it is far cheaper.
            On the few times a year I travel down with the family, I also use HEx as the advance booking and kids go free makes it cheaper (even if we have been using a 1-4 Zone day pass)

          • John says:

            OK, yours is one of the uncommon scenarios where HEx is actually optimal

          • The Savage Squirrel says:

            I really don’t think travelling to Wales and the West Country is THAT uncommon a scenario…

        • BA Flyer IHG Stayer says:

          Yes IF you can get one of the limited number of cheap tickets it is.

      • Londonsteve says:

        I had a colleague travelling to London on business prior to the opening of the Elizabeth Line and despite her final destination being nowhere near Paddington, she simply refused to believe the HEX wasn’t the best way to London. I tried to explain (as a lifelong Londoner) that it was sub optimal to get to Canary Wharf, she was better off taking the tube, she was suckered by the marketing and perceived ‘poshness’ of it all and insisted on using it. If it saved her any time at all to CW, it won’t have been more than 5 minutes compared to taking the Picc line into town and changing onto the Jubillee.

  • Mohamed says:

    I was standing at platform the other day, HEX arrived and you can notice barely 10% of waiting passengers get in while the remaining kept waiting for Elisabeth line, soon HEXwill realise they don’t have monopoly and keep being the most expensive airport train won’t work.

    • flyforfun says:

      I was on the HEX from T5 last Wednesday night. Got to T2/3 and it nearly filled up.

      I took the HEX because I saved my company £120 compared to taking a taxi/mini cab both ways. On my own dime, if I book early enough I’ll take the HEX at £5.50 otherwise I’ll do the Elizabeth line. Took it home after a 25hr flight from Australia earlier this year and it was fine.

    • Tim says:

      The Elizabeth line service would be better if these lightly-used HEX trains were off the track. Just think now much more efficient the Elizabeth line would be if a lower proportion of trains were able to avoid reversing at Paddington. And how much extra mainline capacity would be released at Paddington if GWR gained two extra platforms. This is all because HEX has a contract running to, I think, 2040. After that, I’d be surprised if it survives.

      • Rhys says:

        2028, I think.

        • BA Flyer IHG Stayer says:

          Yes their current concession is until 2028. It was awarded an 5 year extens during the pandemic.

          I’m not sure reversing trains outside of Paddington is an issue, it’s the central core that needs the service not Heathrow. In fact operating more trains from LHR would take up more train paths than the reversing trains as they go into a separate track not used for any other services and allows for the driver to walkthrough the train whilst the train reverses itself into the platform to start its east bound run.

  • David Cohen says:

    I’m hoping that as the passenger numbers for the Lizzie Line increase further, it starts to cost HAL more to run the Hex, than the revenue it brings in.

    The train paths that it currently takes given the presumably lower passenger numbers could be repurposed for more GWR services on the fast up/down lines. There’s then room for further Lizzie Line paths on the relief lines increasing useful and more affordable services for everyone else.

    HAL then continues to win with the various track access charges that they levy on TfL for not having to run any service at all.

  • ClubX says:

    Don’t forget there’s a discount code if you pay with a master card. Works on the day. Making it £22 each way.

  • ClubSmed says:

    If you do not have Heathrow Fast Track security access via your airline, the only other way to obtain it at the moment is as a benefit of HEx First Class.

  • Devon Diamond says:

    Have booked a £5.50 ticket for September. As it turns out it’s quicker and cheaper to get to Paddington than Reading to pick up my train back to the South West
