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.

Depending on how much you like airline lounges, with that kind of layover you could go to at least five lounges:
  • AA Arrivals in T3
  • BA Arrivals in T5
  • BA business lounge, T5 south
  • BA business lounge, T5 north
  • BA business lounge in the T5 B satellite

There might even be more options.

I'd rate AA Arrivals as the best of the five. If it were me, I'd visit AA arrivals, then (if time allows) BA arrivals, then one of the BA T5 lounges (they'd practically identical). Of course if you were EXP you'd have a 6th option: BA Galleries First, which I'd rank as best of the six.

Executive summary: if it were me, I'd visit as many lounges as possible, but I'm probably different than most.

CNX @ LHR from AA100 at T3 (to merge LHR Connection thread)

Will be arriving into LHR on AA 100 (scheduled 6:20) into T3.
My outbound is also from T3 with the flight to PRG to depart at 7:20.
I am BA Silver.
I am afraid that I may not make the cnx.
Anyone has had similar experience?

Upon landing, there will be One World service agents, they have purple jacket if I recall correctly and will hand your connection ticket and might escort you to make connection. Luckily this is same terminal so no need to take the shuttle bus. The only thing is going through security, which might be fast during that time. Good luck.

I've done a few of the quick ~1hr-ish AA to BA/AY, T3-T3 connections at LHR to VIE and HEL. Like a lot of these questions, if you're on time then you'll be fine. Obviously not much time for lounge hopping or anything else, but you should make it to your next gate in plenty of time.

If you're sitting at JFK and the JFK-LHR flight starts getting delayed, then work with the AA agents there in the Flagship Lounge to get rebooked on a later LHR-PRG flight.

JFK-LHR-ZRH 7/3/18 and ZRH-PHL-JFK 7/9/18 issues and comments

Now that non-stops between JFK and ZRH no longer exist, one is forced to connect through LHR and/or PHL [through MAD might also be an option].
(1)Flt. 100 on 7/3 departed 30 minutes late (hydraulic issues with baggage loader) and arrived at the gate 45 minutes later than scheduled, lots of pax had "tight" connections and most likely missed these; an AA agent at the end of the jetway had a large sign with 15 connecting cities listed...new flts were (per FAs announcement) were to be made for them. ["legal" MCTs for LHR should not be relied on.] Further down the road an AA agent had a sign "Concierge Key", were CKs (who were connecting) given FULL VIP service or only going to be transported to the T3 to T5 connecting bus? Several flts arrived in close proximity to AA 100 so there were lots of pax connecting from T3 to T5 = long queues and extra wait times to get on a shuttle.
(2)Once in T5, the Fast Track security lane(s) had issues, one belt was inoperative and the other froze periodically--so even if you had a chance of making a connection, you wouldn't.
(3)I allowed for a 3 hr connection and even with FT issues had time to visit a OW lounge [I've connected through LHR on previous trips and used Gallery North] I even had time to use South, much nicer than North.
(4)For the return ZRH-PHL-JFK the quickest connection leaves 3+ hours in PHL, PHL-JFK departs from F--but for the next 2 weeks the AC in F is under construction, so I had to back-track to the AC in C.
(5)The PHL-JFK taxied for 30 minutes before t/o, the flt took only 35 minutes...
Discussed elsewhere on FT, AAs pull back for JFK (especially in light of my experience) will lead me to look elsewhere (Delta) for future NON-STOPs between ZRH from JFK

Thanks

Thank you for good suggestions - especially the Flagship lounge potential rebooking.

Why on earth would one continue to fly AA between NYC and ZRH? There are so many better and easier options.

Even AAs own corporate clients realized this when AA was flying the route nonstop.....which is why they were dumped

Yeah, you'll likely be fine. AA100 usually lands on time or a little early, since it's in the first early-morning arrival banks.

My trip (7/3-7/9) was part of an AA Vacation Package: (1)Special Fare Method, for EQD and EQM, (2)20,000 bonus miles for a Vacation to ZRH, (3)Price I paid, made the airfare + hotel close to airfare alone.

Thanks for all the updates here from everyone. I’ve found FT to be immensely helpful for someone who doesn’t travel as often but is fascinated by people who live in the sky.

Last month I flew LHR - CLT out of T3 and found the Priority check-in so fast and easy. This time I’m flying LHR-AUS on BA out of T5 and wondering if the process will be the same or if I’m better off going through T3 then taking the bus after crossing Security. Not even sure if that’s possible. . I’m OWS (AA Plat) if that helps explain my logic.

Go thru T5. It’s usually pretty quick, and then you will be right there to use the Galleries lounges.

If you're departing from T5, then by all means go straight to T5 and clear security there. Your PLT status enables you to use the Fast Track there as well.

Starting off in T3 would be a huge hassle and waste of time and involve clearing security twice and a bus ride between terminals, not to mention countless people telling you you're in the wrong terminal along the way.

Just to clarify, if you are coming from landside you can only enter a terminal if you have a bp for a flight departing from that terminal - so going through security at T3 if you are departing from T5 wouldn't be possible.

As a OWS you can use fast track at T5. There is a fast track lane at both north and south security. Tbh I always found the north fast track much quieter. It has a completely separate entrance to north normal security and is 50m to the left of normal security. It is also close to where you arrive on that floor if you are coming in on the HEX or tube.

Thanks for the responses. I am coming landside so the above scenario works great for me. I did follow the lounges thread but I was only able to see the ones for T3. Is there another link I’m missing? This is the link from FT - LHR / London Heathrow Int'l. T3 BA First & Galleries Club Lounges (master thread)
