Link to FT - AA thread London Heathrow (LHR) <-> Gatwick (LGW) Transport / Transfer (master thread)

The vast majority of arriving passengers with a passport from the European Union, Switzerland or, effective 20 May 2019, Australia, Canada, Japan, New Zealand, Singapore, South Korea or USA can now use arrival immigration eGates without any fee or pre-registration requirement. But for those transiting LHR with a non-UK/non-Ireland destination and no luggage to claim during transit at LHR, the eGates are generally irrelevant since most such passengers don’t enter the UK-Ireland Common Travel Area.

NOTE: Connecting flights between Terminal 5 and Terminal 3 - please allow a minimum 1 hour 30 minutes between flights.

If you are unsure which terminal your connecting flight departs from, see "Which terminal does my flight depart from / arrive?"

For gate to gate connection assistance in T-3, AA Five Star Service can be used (fee, must be in AA Business or First on incoming or outbound flight). For interterminal assistance, see https://www.heathrow.com/airport-gui...cierge-service for Heathrow Meet and Assist.

LHR is composed of four terminals (Terminal 1 is now permanently closed). American Airlines and many oneworld airlines (e.g. AY, BA, CX, IB, JL, QF, RJ, UL) use Terminal 3. MH and QR use terminal 4. BA uses Terminals 3 and 5. These terminals are not connected - you can not walk from one to the other. Use this tool to see where your next flight departs / arrives.

Transferring/ Connections at LHR interterminal can be done three ways:

Link to interactive custom Heathrow Flight Connections Guide

1) Landside: exit your terminal and process HM immigration and customs as if you were arriving in the UK, then take the free train or busses connecting to other terminals. With most hotels, if you are staying overnight you will most likely utilise the "Heathrow Hoppa" busses costing £6 for one person or £11 for a family one way, £11 for one person and £21 for a family return; family is up to 2 adults and 3 children. A small discount is available for buying your ticket at a ticket machine in select hotels or via the HH website. You must proceed landside if planning to use the AA (or BA) Arrivals Lounge, which close at 1400 hrs / 2 PM as these are landside. (See post no. 627, here, for local land & hotel transport options.)

Inter-terminal landside connections can be via rail (free) or walking, depending on the terminals. See the diagram for Heathrow Express terminal connections, free when you are traveling within the airport's confines. See here You can also travel between the terminals, or Hatton Cross station, free of charge via the Piccadilly line, but you must touch a contactless payment card/Apple/Google Pay or Oyster card on the faregates at the start and end of your journey. When changing terminals via Heathrow Express or Elizabeth line you can either do the same or get a free paper ticket.


2) Airside:

Follow the signage to Flight Connections, where you will proceed a bus waiting area at airport ground level and take a bus to your next terminal, where you will proceed through boarding pass, carryon check a standard airport security check. Now you are ready to catch your next flight. Flight connections Minimum Connect Times are ordinarily 75 - 90 minutes (the latter for connections between T3 and T5).

NOTE: You must be at your connecting gate 20 minutes prior to departure. If you must recover bags and re-check (e.g. oneworld to non-oneworld or LCC) you must check your baggage in at least 45 minutes prior to departure.

Use this tool available from this page on LHR's website that include a step by step guide through Flight Connections. The page also offers videos. Use this tool to see where your next flight departs / arrives.[/quote]


Typical Terminal 3 to Terminal 5 Flight Connections path:

T3–>T5 see posts 674, 675.1. Welcome to Heathrow!: On leaving the aircraft, please follow the purple signs for Flight Connections.

2. Flight Connections bus: A dedicated bus will transfer you between terminals. Buses are free and depart every six to ten minutes.

3. Airline desks: Need to visit your airline's ticket desk? You'll find it here.

4. Ready to fly: Staff will check that you're in the right place, your hand baggage meets airline regulations, and you have time to catch your onward flight.

5. Hand baggage check: At this point your hand baggage will be checked to ensure it conforms to UK and EU regulations. Please be aware that liquids in containers over 100ml are not allowed through security.

6. Security screening: You will pass through security screening at this point. If you are a non-UK resident and have goods to declare to HM Customs, please use the Customs telephone before security control.

7. Departure lounge: Check the screens in the departure lounge, which will be updated when your gate opens and again when your flight is ready for boarding.

NOTE: Flight departure gates are listed in only sufficient time to get to the gate, not hours (or often an hour) prior to departure.


Typical Terminal 5 to Terminal 3 Flight Connections path:1. Welcome to Heathrow!: On leaving the aircraft, please follow the purple signs for Flight Connections.

2. Flight Connections bus: A dedicated bus will transfer you between terminals. Buses are free and depart every six to ten minutes.

NOTE: As there is a new AA desk at the bus boarding point, you can get your AA boarding pass and pass the AA oral security questioning while you await the bus.

3. Hand baggage check: At this point your hand baggage will be checked to ensure it conforms to UK and EU regulations. Please be aware that liquids in containers over 100ml are not allowed through security.

4. Security screening: You will pass through security screening at this point. If you are a non-UK resident and have goods to declare to HM Customs, please use the Customs telephone before security control.

5. Airline desks: Need to visit your airline's ticket desk? You'll find it here. But see 2A if flying AA.

6. Departure lounge: Check the screens in the departure lounge, which will be updated when your gate opens and again when your flight is ready for boarding.

Lounges:
Airside lounges at LHR are designated departure lounges. You use the lounge in the terminal you're departing from – arriving and departing passengers are separated, so it's not possible (for example) to use a terminal 5 lounge if you are arriving in terminal 5 and departing from terminal 3.

Terminal 3 lounges include:

Airside, departure lounges:
American Airlines Flagship / First Class Lounge - Lounge Zone H
American Airlines Admirals Club - Lounge Zone H
British Airways Galleries First and Club lounges - Lounge Zone F
Cathay Pacific First and Business lounges near Gate 11
Qantas Airways London Lounge - Lounge B / Gate

Landside, for arriving AA and BA long haul passengers who flew in first or business class, or any class if oneworld Emerald (no guest)
American Airlines Arrivals Lounge (recently renovated)

Terminal 5 lounges:

Airside lounges:
British Airways Concorde Room (longhaul BA First)
British Airways Galleries First Lounge - South Concourse
British Airways Galleries Club lounges both North & South Concourses
British Airways Galleries Club lounge T5B Satellite

Landside, for arriving BA First/Club World passengers and oneworld emerald members in World Traveller or World Traveller Plus (no guest)
British Airways Galleries Arrivals Lounge

For hours, access, amenities, etc. consult the oneworld lounge access tool here

Link to the most useful London Heathrow International Airport website. Click on "Connections" for a connection assistance tool.

For long connections where you might wish to go to London, you can use "the tube" (Underground, ~50 minutes, cheapest), busses to various locations, taxis (the most expensive, about 45 minutes) or "minicabs" and other hired cars, the Heathrow Express (15 minutes to Paddington station) or Heathrow Connect (30 minutes to Paddington). You can also Uber or bus to nearby Windsor town, and with sufficient time even tour Windsor Castle.

For links to local and local hotels, other airports (such as Gatwick, ~1:30), railroad stations (Feltham, Watford, Woking and Reading), intercity coaches (such as Oxford) start at this page.

The Tube takes 50 minutes from the Central / Terminals 2/3, T-4 or T-5 stations using the Piccadilly Line. Link to LHR tube page; link to London Toolkit page on LHR and Piccadilly line; link to Transport for London page.

The Heathrow Express / HEX departs T-5 and takes 21 minutes (it stops at Central / T2/3, six minutes) and onward to Paddington (15 minutes, about 1/3 of the time a taxi would take, though a taxi or bus can tale longer in some traffic). The trains have 15 minute headway (depart every 15 minutes) and have baggage racks.

(If you stay at Hilton T-4, board HEX at T-5, go to Central / T-2/3, get off, take the connecting train to T-4 (4 minutes), all free. From T-4 follow the signs to the hotel, perhaps 10 minute walk by covered board walk).

The Elizabeth Line (formerly TfL Rail) costs less, takes 30 minutes to Paddington from the Heathrow stations, and continues to key central London destinations such as Tottenham Court Road and Liverpool Street.

I've had similar T3/T3 connections a few times and all but once had enough time for a quick 20-30 mins of lounge time. Certainly not discounting your data point but there's no reason to cause a first time LHR flyer any undue stress or anxiety worrying about the connection .

im doing the same bcn flight in a week but this time I have a solid 3 hours. Draw of the flights and not by design. I think usually a 145 min connect is ok, and yes 90% of the the time not an issue

but that said lhr and air traffic is such a crap shoot. A little fog and a back up of planes and there goes your day. Let’s also not forget brexit. Bottom line don’t mess about and get through security with speed

Hopefully original poster is either flying pre brexit or well after. God only knows how brexit messes up flights, that date is quickly approaching.

I for for one am staying out of uk airspace until I see how things shape up with flights

Maybe we should keep this thread focused on answering the questions of a poster who is inexperienced with LHR and not introduce a bunch of conjecture about brexit and ATC holds (some of which are accounted for in planned flight times) and taking uncessarily long connection times.

1:25 is generally fine for a T3/T3 connection.

A T3/T3 connection is one of the easier connections at LHR.

OPs bags will be checked through to PHL, and OP will pass through a security checkpoint at LHR T3.

OP will go through EU exit immigration/customs at BCN. There will be no immigration or customs checks during the LHR transfer.

Those are the answers to the OPs questions.

OP said “This is an AA award ticket that was booked all together“, so no worries there.

I did a 1:05 t3 to t3 (from prg) a few weeks ago and had no problems. Even had time to grab a snack from the lounge. LHR security sucks however - make sure to check ALL liquids/cremes/oils etc to avoid any problems.

Best advice I have for successfully (and quickly) navigating LHR security even when not possessing Fast Track privileges (which I inadvertently lost out on during my last transit due to not being able to read signage):
  1. Have all your liquids, creams, oils in a baggie ready to easily pull from your luggage and put on the belt (similar to non-TSA Precheck lines in the US)
  2. Have all your electronics available to be easily pulled from your luggage and put on the belt (laptops, iPads, phones - it all goes on the belt in Europe)
  3. Remember to use one bin per item - don't try to load up a bin with multiple items (particularly make sure to use a bin for your personal item alone and your carry-on bag alone). The person who is helping keep the belt moving may say differently, but you can't go wrong if you start out using one bin per item
  4. Have patience and be polite to the security personnel. Treat them respectfully and they will return the favor (unlike some TSA outposts in the US).
Your connection time should be fine, and, worst case, you find yourself on BA or rerouted through JFK on a slightly later flight.

I ask because the TSA cant find squat in my bag while the ones in LHR, PEK etc. Seem to find and examine my liquids.

Depending on your departure date, if you miss the BA connection to AA737 (the last LHR-PHL AA flight of the day) and want to be proactive, I'd ask BA to be placed on the last BA LHR-PHL flight of the day, which departs LHR around 5PM. I assume this would likely be BA's fault, so there should be little problem with this solution, even though it's an AA award ticket.

That's incredibly unlucky. In the many years and hundreds of times I have been in to LHR I have never been held for that long. That would be 9/10 laps of the hold which would be extremely unusual.

Just as a reassurance to sparkygirl as I don't want here to unduly worry, I would say typical is no more than 5-10 minutes which is usually 1-2 laps of the hold. This is factored in to the flight time. I have had a few occasions where it has been 10-15 minutes. Possibly one 20 minute once. But please do not think 45 minute holding is in anyway typical or even vaguely usual, it really isn't.

I agree with the advice from others like The _Banking_Scot, if this is one ticket you will be fine and it isn't that tight. Just follow the signs for Flight Connections T3, go through security (there is a much bigger flight connections centre that opened in T3 last May), and you will then be in the airside departures area.

Well do you actually feel safer because they examined you hair gel?
(Or perhaps more importantly, is there any empirical evidence that you actually ARE any safer? And I’m not defending the competence of the TSA.)

Back on topic- agree that the connection will be fine ~90% of the time.

Since those liquids do not actually pose the slightest real-world security threat, it sucks. It sucks big time.

I’m flying TXL-LHR-ORD next month and i have a question about luggage. TXL-LHR flight arrives at 5 pm and my LHR-ORD flight departs at 7:45 am next morning. Will my bag be checked all the way they or do I have to pick it up in LHR since I’m overnighting in London? I’ve done this connection before but I did not have a checked bag.

Yes it will be checked all the way through. Just make sure to confirm with the check in agent that they have done this.

You could ask for it to be checked just to London instead if you really wanted it with you overnight, but that just adds hassle.

I don’t want it with me overnight. But I also want to make sure my suit case will be on the flight with me the next morning. I wasn’t sure that they will check it thru because at some airports you can’t have checked luggage overnight.

You definitely can at LHR and it's standard procedure. As I say best just to confirm with the agent at TXL that they've done it (the bag tag will show both LHR and ORD). And for peace of mind you can check with a customer service/lounge/gate agent at LHR in the morning to confirm they see your bag in the system. There shouldn't be any issue.
