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.

This all assumes of course flights are running and we can actually enter our final destination. The UK government seems to somehow be more confused/confusing than the US, which is quite a feat.
I don't think anyone knows the exact details of the quarantine yet for transit passengers if you need to go landside - or when it would be implemented. At the moment the quarantine has been suggested but there is nothing firm. Also I think considering how much is changing it is pretty much impossible to try and predict what the situation would be in August.

Out of interest where have you heard this?

LHR Connection Time

Looking to book tickets TLV to LHR on BA, then connect to LHR to ORD on AA.

One option has a connection time of 1:45 hours, and the other option has a connection of 4:45 hours.

​​​​​​This is for early 2021. We are US citizens flying business class and checking bags. Is terminal change required at LHR? Which alternative would you choose>

1:45 is plenty of time. I’ve done this same journey you’re going to do many times. 1:45 is great.

Especially now that it is a T5-T5 connection.

Currently AA has moved to LHR T5 and all BA's flights are using that terminal too, as aamilesslave said. It is unlikely that AA will return to T3 any time soon or at all according to some, however the bus service between terminals is fairly efficient and you will need to go through security in both cases.

The usual time from gate to gate is about 50 minutes at a brisk pace.

Atm no terminal change is required as AA are temporarily in T5 alongside BA, although who knows if that will be the case in early 2021. For a T5-T5 connection like that you would go through security but not through immigration. Also as long as your bags are checked through you won't need to do anything with them as they will be moved for you on to the next flight. 1hr 45min would be plenty for this.

If AA move back to T3 then when you arrive at T5 you follow the signs for flight connections to T3. You would get an airside connection bus from T5 (you can get it from T5A or T5B) to T3, then go through security at T3. Again no immigration, and no need to worry about bags if they are checked through. I would say 1hr 45min is fine for this too - I am usually in the airside departures area 30-40 mins after stepping of the plane in T5.

T5 to T3 1 hour?

AA has me on a flight that has a connection time of 1 hour. AA lands at T5 and the connecting BA flight is out of T3. Seems very tight in my experience. Has anybody connected through Heathrow recently on a tight connection like this? What are my chances of making this connection?

Is this on one ticket? Minimum connection time is 90 mins between the two terminals so I think this will need rebooking at some point as it doesn’t meet MCT. I am guessing this connection is now 69 minutes due to some flight time changes?

I assume your T5 AA arrival is from JFK?

This is one ticket booked with AA. BOS - LHR - ZAG. I saw the MCT and that is what raised my concerns.

By the way AA is still selling this ticket.

Hi,

What airline is operating BOS-LHR?
If it is AA then AA now uses T3 for all flights ( apart from JFK which remains at T5).
If it is a T3-T3 connection then MCT is 60mins ( still tight but doable)

Regards

AA operates the flight from BOS-LHR. From everything I see it is a T3 to T5 connection.

I guess wish me luck...
