Some confusion may result from a change AA has made to its operations at Heathrow. For several months Terminal 3, AA’s traditional home, has been closed. It’s recent re-opening, first as a red-country terminal and then as home to Delta and Virgin sees AA moving back from Terminal 5, at least in part.
It appears that AA is leaving it’s JFK flights at Terminal 5 for now.
Please note counter opening times for AA:
Terminal 3
Zone C
Daily: 5:30 a.m. – 12 p.m.
Terminal 5 ‐ Flights to New York (JFK)
Main cabin – Zone C
Flagship® Business – Zone C
Flagship® First – Zone J
Daily: 5:30 a.m. – 12 p.m.
The Terminal 3 Lounges are shown as still closed, which will be disappointing for those leaving from there, as BA has T5 lounges open
The BA lounge in T3 is open for people flying on any of the OneWorld airlines at T3 – even though BA isn’t currently operating in T3
It’s all wrong. At T3 open from 6 am till 5.30 PM . Checkin Zone is E at Terminal 3 . BA open the lounge for AA and JAL passengers at T3 . All flights except JFK leaving from Terminal 3 .
For JFK flight AA will open Zone C , 3 hours before the departure . First JFK flight is on 9.30 .AA 101 , 2nd one in the afternoon AA 141 .
At T5 AA pax can use south Galleries lounge F class, concierge key Executive platinum Platinum pro pax can use First wing and F class lounge.
