American Airlines Splits Operations At London Heathrow

If you’re flying American Airlines to or from London Heathrow Airport, the experience potentially just became less seamless…

American now using LHR T3 & T5

As of August 2021, American Airlines is operating flights out of both London Heathrow Terminal 3 and Terminal 5:

  • American flights to & from New York operate from Terminal 5
  • American flights to & from all other destinations operate from Terminal 3

For some context:

American has been operating exclusively out of Terminal 5 for months

This isn’t exactly a great arrangement

To me, American’s new setup seems like the worst of both worlds. From a passenger experience standpoint, it at least simplifies things if all of a carrier’s operations are out of a single terminal. It creates confusion when some flights operate out of one terminal, and some flights operate out of a different terminal, especially at a non-hub airport.

In the past I largely considered Terminal 3 to be better than Terminal 5 from a oneworld lounge standpoint, as Terminal 3 had both the exceptional Cathay Pacific First Class Lounge and the Qantas Lounge, which oneworld Emerald members had access to.

The Qantas Lounge Heathrow is closed right now

Unfortunately both of these lounges are closed, with no timeline for when they’ll reopen. The only oneworld lounge in Terminal 3 is the British Airways Lounge, and only the business class section is open. That’s quite a downgrade from the lounge setup in Terminal 5.

I’m curious to see how this situation plays out in the long run. If it’s important for American and British Airways to operate from the same terminal, then they should just have all operations in Terminal 5. If not, it seems better to just stick all operations in Terminal 3.

Bottom line

American Airlines relocated all flights to Terminal 5 at London Heathrow Airport in the summer of 2020. While this coincided with Terminal 3 closing due to lack of traffic, it was part of a long-term plan for American to move to Terminal 5, to be closer to British Airways.

With Terminal 3 having now reopened, most American flights are once again operating from there. Unfortunately with most lounges closed in the terminal, it’ll be a pretty disappointing ground experience for passengers.

What do you make of American operating out of LHR T3 & T5?

I need some help. I am flying into LHR from Chicago on AA. So I assume I will arrive in terminal 3. My layover is overnight… but a shorter one. I get in at 10:30 pm. Then at 7 am the following day I fly BA out of terminal 5. Not sure what to do for the overnight. Any suggestions?

I personally believe American should move all its routes and operations to & from the United States to Terminal 5 allowing for seamless travel on both AA & BA !

Worst connection situation ever. Terminal 5 to terminal 3, dealing with American transfer passenger section. Almost 2 hours alone and completely repetitive of original checkin system. I felt bad for the people working behind the counters to always be in stressful situation. They absolutely need more people working there or more efficient process for all the people with short connections.

Dealing with this today and it’s brutal. They have not updated the bus schedule. You’ll be waiting for up to an hour just to get the bus from T5-T3. The buses are only running every 30 minutes and they are limiting the capacity so you won’t get the first one. Typical LHR cluster. Don’t book tight T3-T5 connections here unless you want to deal with missed connections. Anything less than 2 hours you will not make right now.
