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.

Greetings all,

I am flying MIA-LHR-HAM next week. This is 2 separate itineraries meaning MIA-LHR is on one ticket with AA, and then the onwards leg was booked with BA. I have 2 hours connection time and not checking a bag. Will I be able to stay airside and simply switch terminals (assuming I can check in at a connections counter or obtain my boarding pass online for the BA flight)

Any help is appreciated thanks!

Yes, this is no problem. After arriving just follow signs to flight connections and hop on the bus to T5. Either do OLCI and print your LHR-HAM BP, or just stop a the BA desks once you get to T5 before the conformance/security checks.

You can stay airside, but you will have to switch terminals and go through LHR security.

Your AA flight will very likely land in T3 and your BA flight will likely leave from T5.

Here's the drill. You land and follow the crowd down the concourse. Look for purple "Flight Connections" signs. Follow those purple signs that direct you to T5. That will take you to a bus waiting area. Get on the bus then get off at T5.

Upon arrival in T5, go up the escalator and again follow the purple signs to Flight Connections. Here is the place where you will get your new boarding pass. (Either that or download the BA app and get a mobile boarding pass.) Next is Flight Conformance. Someone will check your boarding pass, then send you up an escalator to LHR T5 Security, where you will go through the full security check. Unless you have heavy clunky shoes (avoid), you can keep your shoes on, but laptops, tables, Kindles, 3-1-1 liquids, etc, all come out of the bag.

After Security, you go into the main lounge area. They do not announce gates until they are ready to open the gate to departing passengers. In other words, you can't just go to your gate and wait there. Find a place in the departure lounge where you can watch the TV monitors and wait for your flight's gate to be announced, then make your way to the gate. Don't dawdle. They expect people to go directly to the gate once it's announced.

If you have extra time, you might want to walk around T5 to acquaint yourself with the layout before your flight gate is announced on the TV monitors.

Some flights leave from the two other T5 terminals, namely T5B and T5C. Usually they announce that on the TV monitor so you can make your way to T5B or T5C then wait there for the gate assignment. If you have to go to T5B or T5C, you will take a mini-train. The elevator to the T5B and T5C mini-train is on the south side of the terminal, clearly marked. Ask someone if you are unsure.

Note that the mini-train trip is one-way. You can't just get on the train to go sightseeing, then come back to T5A. When the mini-train gets to its destination, they check to see the train is free of passengers before letting the next group on. This way they isolate the arrivals from the departures.

When it's time to go back home, you'll do the same thing in reverse. Land at T5, follow the purple Flight Connection signs to the bus to T3, then go through LHR T3 security, then wait in the departure lounge.

Not likely, this will definitely be the case for AA>BA MIA-LHR-HAM next week,

Good advice, a couple of extra points:

The deadline for conformance (boarding pass check at T5 connections security is 35 mins prior to the scheduled departure time of the onward flight. It's possible there is a little flexibility on this (not if coming from landside), but don't count on it. If possible print (or download via BA app) your onward BP, this can be done from 24 hours prior to the departure time.

In T5 gates are mostly announced (on screens) 1 hour prior to scheduled departure. Not really the case that you need to go immediately for a short haul flight, these are unlikely to board more than 30 mins prior to scheduled departure (except perhaps gates A4 and A10 for remote stands)

Majority of short haul flights go from the main T5A terminal, but it is possible that it will be T5B/C. Best to stay in T5A until the gate is shown on screens, since these can change even last minute at LHR. The shuttle train elevator is pretty much in the centre of the terminal.

Not strictly true, but maybe better to leave it like this for a beginner

2 hours "connection" on separate tickets is brave, though of course quite possible if the TATL is on time (or even up to an hour late, but be prepared to run in that case).

They no longer do any checks at T5C before the transit comes back to T5A. This is a way to "land" yourself from the departures area in T5, staying on the transit means you swap to the arrivals stream in coming back from T5C.

True. I fly every year LAX-LHR-Germany, usually DUS. Every year I have flown out of T5A to Germany.

This year was the exception. Due to a late-arriving aircraft and difficulty finding a gate, our flight was from T5C. Thanks to the BA forum people and their detailed messages on LHR transfers, I was prepared for the mini-train and knew where to look for the elevator.

I'll be connecting from a non-OW flight (UA, terminal 2 I assume) to a BA flight (terminal 5 I assume) with a 1:50 connection. Is it better to check bags or not check bags for this transfer? I assume I'll have to re-clear security? What's the easiest way to make that transfer? I believe bags can be checked through since I booked the flights together (through United).

If it's booked on a single ticket through UA then your bags will be checked through. LHR sees tons of connections like this, so it's not unusual to have bags connecting from T2 to T5, etc. What is your final destination on BA? It's easy to search online and see if you will depart from T5 or T3. Once you land at LHR, just follow the signs to flight connections and take the bus to T5 or T3. Once you arrive at T5/T3 there will be BA desks if you need to get your boarding pass, after this you will clear security again and then be in the departures area.

Yes, you will re-clear security upon entering your departure terminal. That is a given. You just get off your arriving flight and follow the purple Flight Connection signs.

The LHR website has a nifty "Flight Connections" tool. You enter your arriving and departing flights/dates and it kicks out step-by-step detailed connecting instructions, including inter-terminal transfers. I've never been steered wrong by it.

I'm assuming that this is airline related and not gate related? For instance if I'm flying in on AA and out on BA it'll just give me the directions from T3 to T5, or by inputting the flight numbers and dates will it provide gate to gate information closer to the day of travel?
