I will be traveling to Oxford, UK this summer. My flight lands at Heathrow around 12:30pm on a Sunday; it is on British Airways so I believe it will arrive at Terminal 5. Based on this map and other resources, it appears that one can take a train from Heathrow to Hayes & Harlington station, and then change to a train bound for Oxford, thus avoiding the need to travel into central London and backtrack.

However, on closer inspection, it looks like the trains from Terminal 5 stop only at Terminals 1,2,3 and then run express to Paddington Station, without stopping at Hays & Harlington (I think this is the so-called Heathrow Express). So I would need to first transfer to one of the other terminals' rail stations and catch a train from there.

  • Is it reasonably convenient to transfer between terminals like this? Some sources seem to suggest that the best way is to take the Underground to the other terminal. How easy is it to get from the Underground station to the rail station at the other terminals?

  • Would it be better to transfer to Terminals 1,2,3 or to Terminal 4?

  • Are there other good options that I am missing?

I will probably not have an excessive amount of luggage.

    There is bus running directly from T1,T2,T3 Heathrow to Oxford City Centre, is that of any use?

  • @GayotFow: Thanks, I will look into that. But in general I would rather take trains than buses, even if it requires another transfer. Apr 25, 2015 at 23:02
  • @GayotFow And Terminal 5. Apr 26, 2015 at 10:08
  • FTR, Terminal 4 is a total pig to get to from any other terminal. Avoid, avoid, avoid. Apr 26, 2015 at 10:09

    Confusingly there are two types of Heathrow > London train. "Heathrow Express" doesn't stop (and is more expensive because it's faster), while "Heathrow Connect" does stop at all the towns in between. Also, to add to the confusion, you can get the London Underground from Heathrow Airport to nearby towns Hatton Cross and Hounslow (I say confusing because, these stops aren't really in London, and I believe it's not underground...)

If you just want to get from Heathrow to Oxford - Don't take the train!

Until they get round to building the western approach spur into Heathrow, taking the train between Heathrow and Oxford is a faff, and it isn't all that cheap either. You either need to take a train into Paddington, change platforms, then head back out to Oxford (minimum journey time 1:20, likely closer to 1:45), or take a Heathrow Connect train to Hayes and Harlington (change at T123 from T5) then lug your stuff up and over to change platforms then take a slow stopping train.

Instead, what you should do is take the Oxford Airline bus. It starts at the central bus station for T1/T2/T3, then goes to Terminal 5, then onto the motorway to Oxford. The buses are frequent - every 30 minutes for pretty much the whole day, and sometimes even every 20 minutes at peak times. Depending on traffic, you're looking at between 60 and 80 minutes from Terminal 5 to the centre of Oxford, quicker if you're going to Headington.

The buses are new, have free wifi, have power sockets, have a toilet, have OK leg room, plenty of luggage space etc.

The bus stop at T5 for the airline bus is pretty much straight outside of where you come out of baggage claim and customs, just dog-leg round all the people waiting outside baggage claim and head outside. Stand 10, the dedicated stop for the Oxford Airline bus is pretty much there. Handy tip - if you have bags, queue up about 10m to the right of the bus stop, and you'll be in the right place to put your bags straight into the luggage storage area!

(I've tried the train a few times, but via London Paddington and changing at Hayes and Harlington. Unless you have a very strong reason to need to take the train, such as needing to stop off part way, the coach wins every time!)

    Also, the buses run 24 hours a day (though at a somewhat reduced schedule overnight). The trains don't. Apr 26, 2015 at 9:39
  • He's right! Bizarre as it may sound it's relatively difficult to get to Oxford by train. Apr 27, 2015 at 8:42
  • It's worth noting that the service between Heathrow and Oxford is a coach, not a bus (despite the name of the linked website). The coach will have proper facilities on board, including a large, separate luggage hold for your bags. Oct 15, 2018 at 13:46

I strongly recommend the "Airline" bus service over the train. I live in Oxford and fly from Heathrow several times a year: I always use the bus and wouldn't even consider the train.

  • It's cheaper: about £30 vs about £40 for a one-month return.
  • It's faster: about 75-90 minutes for the bus, vs 100-150 minutes for the train via London.
  • It runs 24 hours, though only every two hours in the middle of the night; there are no trains between around 2345 and 0500. (Included for completeness: not relevant for you since you're arriving at midday.)
  • It leaves directly from the Heathrow Central Bus Station (Terminals 1–3) and from Terminal 5 so you avoid having to mess around transferring terminals at Heathrow, which is way harder to do than any other international airport I've ever been to, except Paris Charles de Gaulle. (Terminal 4 is a pain however you try to travel.)
  • It takes you straight into the centre of Oxford, saving you a 10-minute walk from the railway station.
  • It's a direct journey versus having to change once or even twice on the train. IMO, this is a huge win when you've just come off a transatlantic flight.
  • It's more comfortable: a long-distance-style coach with reclining seats, footrests and decent seat pitch, rather than a commuter-style train.
  • The driver deals with your baggage, vs you having to find space for it somewhere on the aforementioned commuter-style train.
  • The bus has free wifi.

The only disadvantage of the bus that I can think of is that, as far as I recall, they only accept cash. However, you can buy a ticket online in advance and there are plenty of cash machines at Heathrow anyway. If you buy a ticket online, it's valid on any bus for 24 hours after the time you choose. In theory, you only have a seat reserved on the bus you book for; however, I've never been on one of those buses that's been more than half-full so gambling on an unreserved seat is hardly a gamble at all.

If you're worried about not knowing where you are on the bus, the driver announces the stops and, in any case, if you're going into central Oxford, that's the end of the line.

If you really do want to take the train, take whichever trains the timetable says are fastest. That will probably involve going into central London but the lines to Heathrow and Oxford both go from Paddington Station so at least you don't have to navigate London. If you try to optimize for distance travelled, you'll end up on slower trains that will probably take longer. Note also that there's only one train an hour from Heathrow to Hayes and Harlingdon, which can leave you standing around for a long time.


Besides taking a train, you can always use a coach (i.e. bus) to get from Heathrow directly to Oxford. There are a couple of options. One choice is Oxford Bus The Airline - it stops at terminal 5 as well as the central bus station and takes about 80-90 minutes to reach Oxford. The coaches run every 30 minutes. It'll probably be cheaper than a train, too.


The Heathrow Express is free between Terminal 5 and Terminals 1,2,3, where you can do a same-platform transfer to Heathrow Connect which will take you to Hayes & Harlington.

(Likewise, Heathrow Connect is free between Terminals 1,2,3 and Terminal 4, for people arriving on Heathrow Express).

So you don't need to bother with the Underground for this connection. The Underground stations are separate from the Heathrow Express/Connect stations, so there would be some corridor walking involved in that, not to mention that you do need a tube ticket to take the tube between terminals.

Note that some connections from Hayes & Harlington to Oxford will involve a transfer in Slough or Reading -- check times at nationalrail.co.uk before you leave.

  • Thanks, that is valuable information. How does it work specifically? Do the conductors just not check tickets until after leaving Terminals 1,2,3? Apr 25, 2015 at 23:01
  • @Nate: Correct. It's not as if there's much time for a ticket check on the short inter-terminal ride anyway. Apr 25, 2015 at 23:09
  • 2
    Conductors will walk through the first class area on inter-terminal transfers, charging or kicking people out. Announcements and videos and signs all make clear that transfer is free in standard class only. Conductors then do a ticket check + ticket sales after leaving T123

    Don't take the train. The "Airline" buses are much more convenient. Apr 26, 2015 at 9:39
  • "some connections from Hayes & Harlington to Oxford will involve a transfer in Slough or Reading" -- arguably some of the best ones do. Depending on the specific service and time of day, sometimes the fastest is to get off a train at Slough or Reading, that's stopping at Oxford, but will be overtaken before it gets there. You don't want to be on a slow stopper between London and Oxford, some of them take literally twice as long as the fast trains. But I agree with David, the bus is "the way to get to/from Heathrow" and anything else is a diversion. Aug 11, 2016 at 21:11

Since there's no accepted answer for this, I thought I'd note that the Elizabeth Line has added another valid option.

Elizabeth Line from Heathrow (all termini) to Hayes and Harlington, reverse direction on the Elizabeth Line to go out to Reading, then National Rail from Reading to Oxford. At many times, this is National Rail's journey planner's recommended route, it's cheaper at nearly all times than the via-Paddington route, and takes about 1h20m-1h40m, depending on connections.


Yet another option (I cannot vouch for how good it is compared to the others since I've never done any of them) is to take a RailAir coach to Reading (it appears that the journey time from T5 is 38 minutes) and then a train to Oxford (which I take very regularly and is usually 27 minutes). Trains to Oxford from Reading are frequent as it's on the line from Paddington. Both tickets together should not cost you any more than £35 according to what I can find on the relevant websites.

    In some ways it's the worst of both worlds - higher costs + changes + bus stops nearer the city centre than the train. Also, Oxford<->Reading fast trains take between 25 and 35 minutes, depending on if they stop at Didcot, and if they're likely to get stuck behind anything else

    Noted, all those are reasons that this is probably not the best option for the OP. However, it's usually worth knowing that viable alternatives exist. You never know what freak circumstances can occur on your travels, and this might be useful to someone else reading this question.
