I'm a little confused if there's a oneworld lounge in BGI. BA lists a contract lounge while oneworld.com shows a BA Terraces lounge.
To make it short: Is there a (oneworld) Lounge I can access flying AA (BA Gold/ow Emerald)?
Programs: AA (EXP), Hilton (Diamond), SPG (lowly Gold)
I asked the AA agent at check-in, and I couldn't quite hear the response (even repeated) because the agent spoke quietly in a noisy environment, but I did catch "BA" and "transportation," so I think I was being told that there is a lounge for BA passengers, but it requires transport to and from, and no one would provide that to an AA passenger.
On BA's website many BA-branded lounges are classified as "3rd Party Lounge." However, I believe this merely indicates that the staff are contracted and are not BA employees. Since on OW's website it is not listed as 3rd party-operated and the fact it is called "Terraces," I believe eligible OW elites and J / F PAX should be allowed access when it is open provided that capacity is not an issue. (I believe BA can cite the capacity rule since it probably only has enough space to accommodate BA PAX.) The BWI Cheasapeake lounge is a similar case, where only BA's website (and not OW's) indicates it as 3rd party-operated, and I have accessed that several times when travelling on AA domestic FLT. Those who plan to do so should bring a copy of the OW lounge access rule with them though, which is what I had to do for accessing the BWI Cheasapeake lounge.
Have flown on BA out of BGI, did have access to the lounge - the lounge is NOT a true Terraces Lounge and is lacking in ammenities. I guess it is better than no lounge, but definitely nothing to get excited about.
