If you’ve ever transferred flights between American Airlines and BA at London Heathrow Airport it might have annoyed you that you had to change terminals to/from Terminal 3 in order to catch your connection – this will now change effective tomorrow July 7, 2020 as the carrier moves into British Airways’ Terminal 5.
Terminal 3 where American operates for as long as I can think back is sort of a collection all all different airlines including most oneworld carriers such as Cathay Pacific that also operate their own lounges there (T3 airlines have temporarily moved to T2 in late April as part of a consolidation effort due to Covid-19).
