New RailAir route from Watford to Heathrow, and improved Woking times from today

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

In 11 years of HfP we’ve never looked at RailAir, so I thought the launch of their third route – RA3 – and improvements to the Woking service from today were a good excuse.

If you travelling to London Heathrow by rail from central London, you aren’t short of options. As well as the Piccadilly Line tube trains, you now have the Elizabeth Line, capable of whizzing you from the West End, East London or even Essex directly to the airport. The Heathrow Express continues to operate from London Paddington every 15 minutes.

RailAir coach

Great news if you live in London. If you live to the west of Heathrow, it’s a different story. There is no direct rail link heading west from Heathrow – even though platforms for such a service already exist at Terminal 5 and have done since the terminal opened:

Heathrow Terminal 5 unused national rail platforms

In theory a new rail link from the airport, using these platforms, would join the Great Western line between Langley and Iver. The chance of this getting in done in my lifetime appears slim.

With no direct link, the RailAir ‘luxury’ coach service, operated by FirstBus, fills the gap.

Where does RailAir run?

Ignoring the new route for a moment, the two existing RailAir routes are:

  • RA1 – Reading railway station to Heathrow Terminals 2, 3 and 5, 40 minute journey time
  • RA2 – Guildford and Woking railway stations to Heathrow Terminals 2, 3 and 5, ‘under 1 hour’ from Guildford and ‘under 40 minutes’ from Woking

RA1 runs virtually 24 hours per day, from Reading at 02.40 to 23.05 and from Terminal 3 at 04.05 to 00.15. Buses run every 30 minutes except in the late evening.

RA2 runs from Guildford at 02.30 to 00.00 and from Terminal 3 at 03.58 to 00.28.

Woking services improve from today, 20th August

There are changes – improvements, actually – on the Guildford and Woking route from today.

Guildford services will remain hourly, as previously, but the service from Woking will operate every 30 minutes. This means that some services will start in Woking whilst others will be a stop on the Guildford to Heathrow route.

What is the new route launched last month?

RailAir now also operates from Watford.

Buses go from Watford Junction and Watford town centre to Heathrow.

Route RA3, as it is known, runs from Watford Junction between 03.55 and 23.00. Return buses from Terminal 3 run between 04.35 and 23.40.

The RailAir website has full timetable showing all intermediate stops.

What facilities do you get?

I’ve never used RailAir, but the website advertises free wi-fi and free USB charging. Some seats are in blocks of four with a central table, which is handy for families.

It also advertises a ‘VIP Lounge’ at Reading – this is described as ‘spacious’ and offering ‘complementary hot drinks and newspapers’.

All coaches are fully accessible for wheelchair users.

How much is RailAir?

It’s not cheap, to put it mildly.

Bought online in advance, a single ticket from Reading is £22, with a return being £30.

A single ticket from Guildford or Woking is £9.50, with a return being £17.50.

A single ticket from Watford is £9, with a return being £18.

There is a premium if you attempt to pay cash on the day.

The cost of a child ticket varies. From Reading, Guildford and Woking they get a discount of roughly 50%, but you may still find an Uber is cheaper for a group. On the new Watford route, children under 16 are free.

If you have more than two suitcases per person there is an additional charge.

You need to select a particular service when booking. You are guaranteed a seat on this service, but if your flight is late you can take any other service on the same day, subject to a seat being available.

RailAir tickets are available as an add-on to National Rail fares.

Any thoughts?

RailAir is something I have never tried. If you are a regular user and have any feedback or tips, please leave them in the comments.

    Obviously you can now take the Elizabeth line to Hayes, then change platforms to get to Heathrow.
    Which I would still prefer to risk getting stuck on the M4.

  • HighlandTB says:

    We travel regularly to Heathrow to visit family who live near Woking, does anyone know if the bus does stop to pick up passengers at the McLaren roundabout?

    • HighlandTB says:

      Thanks I think it will be fine being picked up from the roundabout but on the return going to Woking. (To avoid any bad weather!)

  • P Purcell says:

    Very expensive to & from Reading on RailAir. For Reading/Twyford-Heathrow I get the train and change at Hayes & Harlington

  • Paul says:

    When I lived in Woking I used to catch the bus a lot. You say it’s not cheap but it’s at least a fifth the cost of a cab and most of the time I was happy to trade a little extra journey time for the price.
    My experience was that they were on time and reliable, with decent Wi-Fi

  • Liz says:

    What’s the best app to use to buy a combined ticket if we’re taking a train to Watford Junction and then RailAir to Heathrow and want to use a railcard to get a discount? Some of the apps I use to buy train tickets are not showing the RailAir coach as an option.

    • tony says:

      I’m in a similar position and typically find with a network railcard you are better off buying two separate tickets. But as made very clear in the article the Reading service is so expensive that for me it’s typically cheaper to go to Paddington and come back our to the airport

    • BA Flyer IHG Stayer says:

      i would use the national rail enquiries website as that will link to one of the train operators sites.

      Sometimes with the apps the additional ticket types are deeper in the booking pricess

      On LNER app for example you need to click on ‘mix and match tickets’ to get travel card included options so the train + coach option could be in there.

    • ChrisBCN says:

      And NEVER use an app that charges you booking fees (eg Trainline). Use only the apps that are run by the train companies themselves, all of them can sell you a ticket from anywhere to anywhere. The operating train company all is usually best as you may occasionally (well, rarely) find a discount – but it is better for delay repay if you need it.

      • BA Flyer IHG Stayer says:

        Indeed.

        I use LNER even though I’ve not traveled on them in ages.

        But they sell vouchers which you can often get rebates on via credit cards and airtime.

        I’m currently being offered 5% on both and they stack.

        • Ruralite says:

          Yes I find LNER good, especially when you can combine with an Amex offer. They’ve also just sent me a 20% off code for my birthday.

  • jj says:

    It’s telling that there is only enough demand for two buses an hour from Reading. That’s a drop in the ocean compared with the volume of passengers at Heathrow, a decent proportion of which will be coming from the West.

    Outside London, public transport has so many issues if you want to get to Heathrow. My local station has only 4 trains on a Sunday, for example, compared with >50 on weekdays. Only 40% of trains in Wales run on time with multi-hour delays on the Great Western main line being common, so you need to allow massive contingency. You can’t get back to most of Wales after the early evening, so you risk being stranded in London. Flexible fares, essential in case of delays, are usually more expensive than the cost of driving and parking. You can’t take large sporting equipment on the train. Multiple connections become impractical if you have heavy baggage.

    I always consider the train and/or Railbus as a possible transport solution. I use it less than one time in five.

  • Greenpen says:

    I have used the Reading RailAir service quite a few times as there is a direct rail service from my home town. But not if carrying luggage as the hassle and physical effort required to get to my station and then to the bus stop at Reading is too much!

    Some time ago they added a loop off the motorway to allow passengers to be picked up on the outskirts of some town. I have had to suffer this slow loop several times and no one ever gets on! It adds about 15 frustrating minutes to the trip. I think a timetabled 40 minute trip is unrealistically optimistic as if you are not the first stop at LHR then even more time is added on.

    The lounge is fine if it’s cold and wet outside but it’s just a waiting room. WiFi on the bus works well.

    By the way, four pages of comments before 10 on a Sunday morning seems to suggest a demand for information and hints on bus bargains!

  • acewoking says:

    We live in Woking, but 20 minutes walk from the station. It’s not worth getting a taxi to the station then waiting for the bus, so we just get a taxi to Heathrow. On the way home, we take the Railair to Woking, then a taxi from the station, there are always plenty waiting there. The cynic in me thinks that the 30 minute service gives them an excuse to cancel more buses, their thinking is that it will still only mean a 1 hour wait not a 2 hour wait for the next one.

    • polly says:

      Agree, it’s only useful for me going to LHR Dublin alone. Once it’s 2 of us, it’s a taxi, am afraid. We live 10 mins drive from Woking station. And hope it’s not cancelled.
