Please read the wikipost at the top of this thread. A link to the Heathrow interactive connections guide is among the resources.

If you are connecting, it's best to follow the Flight Connections channel and being bussed to the other terminal.

If you are going landside, the train is free and speedy.

You are right. The AC at T3 is fairly decent. I actually liked it better than the business lounges in T5. The Galleries South lounge was very crowded when we were there.

wrp96, thank you for that answer. I should have guessed it was something that simple.

JDiver, I actually have read the Wiki and used the interactive tool. I was confused about the difference between trains and buses. wrp96 answered my question.

These are trains to and from central London that stop at several stations inside Heathrow, not a dedicated inter terminal train system. You are free to use them within the airport but they are not designed for those connecting within Heathrow. The train stations are not particularly convenient and the trains are infrequent.

Yes. In the T3-T5 instance, Heathrow Express trains are free (within airport confines) and headway between trains is 15 minutes. The train terminal serving T-3 is a walk of perhaps 5-10 minutes from arrivals hall (down at "basement" level) to the Central Terminal.

T5 requires a bit of walking and lifts.

Personally, I'd say 30 minutes is a more realistic and comfortable time for labdside train connections T3-T5. 20 if it all works properly, you know where you are going and walk at a good pace.

If I do see a pattern is it safe to plan the 2 hrs. to T5 without the worry of a change making it impossible to return to T3 on time?

Is there a reason you want to go back to T3? BA 598 leaves from T5.


We have an 11 hr. layover. We're in Business so able to get into Galleries Lounge in T5. I've searched and haven't been able to determine if we can access Galleries Lounge in T3. Do I understand it right that there are 2 Galleries Lounges in T3, both a First and a Club Lounge?
Just go to the Galleries in T5. I am still confused as to why you want to go back to T3.


To make the day more interesting, would it be advisable to split the time exploring both T3 and T5? I'm also wondering about splurging on Elemis Spa. Usually I'm too frugal (cheap) to do much of this but trying to make this long layover part of the vacation experience.
NO you can't do that (not since 9/11). Your boarding pass is for T5 so you'll not be able to get to airside on T3.

Thank you all for the insights. Thanks especially to Microwave for taking the time to write such a detailed response.

If we did just one thing it may be the library to see old manuscripts. We watched a Rick Steves video and there were several things but I would rather do one thing relaxed and have a bite to eat than rush around to do too much.

After some more research I'll come back if I still have questions.

Thank you again.

Sorry, total ignorance to how the airport is laid out for traffic flow. That's why I'm asking questions.

I'd appreciate opinions on this plan and it's feasibility.

I looked over things to do near the British Library and found King's Cross Theatre is running The Railway Children on a 2:30 matinee. Production takes about 2-1/2 hrs. which would get us out of there 5ish. Our flight is at 8:15.

We land at 9 a.m. Flight arrived 1/2 hr. early today. Considering everything is on time, I'm trying to guesstimate time to get through LHR to tube would be 1 hr.? No bags to drag around. No shower. ;) Train is supposed to come every 5 mins. We have to add time to figure out what we're doing and pay for train. Train to British Library is 54 mins. So now we're up to 11-12p.m. An hour or more in British Library and bite to eat. Would we walk or take cab to Theatre? We're walkers but I would say we'd probably not want to walk faster than 2.5-3 mph to Theatre. I'm seeing rail lines on map and don't know what walking conditions are like between Library and Theatre. Need to account for time back to underground and be ready for next train. Will train go directly to T5?

It is definitely possible to access T3 via Flight Connections without a T3 boarding pass, however the process of getting in and then getting back to the proper terminal could well be confusing, and there's no real benefit.

Now I believe a good plan is beginning to take shape. :) With no bags to claim and Fast Track immigration access at Heathrow, you should be landside in 20-30 minutes max. Follow yellow signs for Arrivals, once you're in the immigration hall look for Fast Track and present the invitation you were given on the plane. You'll need an address for the immigration card (which you should have received on the plane with the Fast Track invitation and already completed to save time), you might want to put the British Library address on since you're only here for a few hours and that's your first big stop; once you're through immigration head downstairs and look for the big green exit and walk through it. From there, follow signs for the Underground: walk straight out the exit (past the mini duty free and Heathrow Express hawker) and it'll be slightly to the right. You'll have a few tunnels to traverse, and you'll need to figure out tickets as you mention. If you want to get Underground transport sorted in advance, and don't mind paying a slight premium to do so, you can buy Oyster cards from the US preloaded with enough money to suit you for the day. They never expire, so if you come back to London you can reuse. This will save you queuing at the station on the day. The 15 card will give you more than enough credit to do all the public transit you'll need to do on the day, and leave you with a few pounds for your next trip.

Once you've entered the station, look for the platform toward Central London. This is where most everyone else will be waiting as well. As you noted, you're looking at a ~1 hour journey in to Kings Cross. Once you arrive you'll find plenty of lunch options nearby, I'd suggest looking for something that isn't in one of the two massive train stations as there are restaurants in the neighbourhood worth trying. The British Library is very close to St Pancras station and well worth a visit, and it's a very short walk from there to the place where The Railway Children is being done. Note that the venue is not a traditional theatre, it's sort of behind Kings Cross station, maybe 10 minutes by foot if you take a circuitous route. Once your showing is out, I'd go directly to the underground again (there will be lots of people leaving the performance for the underground I'd imagine, and I'm sure they can help you find a nearby entrance), and take the first Piccadilly line train with a destination of Heathrow Terminal 5. You'll have another ~1 hour journey, and upon arrival just follow signs for Departures (take the lifts, they're faster). You'll end up at Terminal 5, large overhead signs will show which security queue is faster though I find South is almost always the quicker one. If your European flight is in business as well, you'll have Fast Track security access again, just have your boarding pass ready to get through the gates and you're set. Lounges are well signed, I prefer the South Galleries Club lounge to the North as it's slightly larger, but both will probably be relatively empty at this time of the day as most US flights are long gone.

Just to help with your fears, even if you end up on a Piccadilly line train leaving at, say, 5:45 PM, you'll be at Terminal 5 before 7 PM for your 8 PM flight. As mentioned, the terminal won't be too busy at this time, and an hour is more than enough time to go from the ticketing area through security to the departures area. The cutoff is 35 minutes to be at the entrance to security, so even with these generous times you've got padding, though I would go directly from the performance to the underground without lallygagging. Good luck with your travels!

Westbound Piccadilly line services can go to two different branches, either Heathrow or Uxbridge, but the stations have clear electronic signage saying where the trains are going. This is repeated on electronic signs inside the trains and on audio announcements at every station for the benefit of blind customers. (What you want to hear is "This is a Piccadilly line service to Heathrow Terminals 1, 2, 3 and 5")

I think the Tube is an easy system to understand when you are on it, even if the lines look complicated on the map.

Thank you, thank you. So very gracious of you to take such time.

I'm looking online to purchase the oyster cards. Is that 15 per person or will the 15 take care of both our fares?

Thank you. Every bit of info helps with familiarity. I do appreciate the time.

I'm also thinking the Elemis spa courtesy treatments may be restricted to longhaul BA First passengers and BAEC Gold members? I suppose treatments may also be available for fees, arranged upon arrival at Terminal 5A South lounge, Terminal 5B departure lounge or Terminal 5 Arrivals lounge. (And for the return, Terminal 3 BA Galleries departures lounge as well.

The OP will be required to exit T-3 either landside via HM Immigration and Customs or to T-5 via the Flight Connections channel, with no opportunity to use any T-3 lounges outbound to VCE.

I'd certainly check my baggage through and heed the excellent advice given by Microwave, picking up some GBP at a T-3 arrivals hall cash machine and heading out of Heathrow for a few hours, unless some condition precludes that.

Thank you for your insight. Most the time I would do carry on luggage but this time we're going as light as possible. One handbag with only the necessaries.

I'm using a Chase Sapphire credit card. Will I still need GBP? If so, how much?

Okay now I am curious what this option is? I do like the CX lounge in T3.
