For Flagship Lounge access, I know as an AA plat and BA Gold (One World Emerald) I would have access even when just traveling AA domestically by showing them by BA card (physical or digital). Am I also allowed one guest who is also traveling domestically with me on an AA?

Your AA plat does not confer entrance on a domestic flight, so it's not relevant here. You get a guest as a BA emerald, but I don't know if you need to use your BA number on your AA flight for access. You should, IMO, since BA is picking up the tab of your lounge entry, and you otherwise wouldn't qualify for entrance.

Flying LAX-MIA-CHS in flagship J (77W). I know I should have access to FL upon arrival in MIA and I was wondering what the best lounge options would be in LAX.

I'm a little confused about the "departing on or connecting to" language.

If I'm AA Platinum Pro (emerald) flying in Y from MAD-JFK-DCA, will I have access to the JFK Flagship Lounge on arrival from MAD?

thanks!

Yes. You have a same day qualifying flight (MAD-JFK) and are connecting to another oneworld flight.

If I fly JFK-LAX-LAS, with JFK-LAX in F, will I get access to FFD during my connection at LAX as well, or just flagship lounge access?

Thanks!

You can access FFD at LAX on arrival.

LGA Lounge
 

Has anyone been to the new lounge at LGA? It is now between gates 30 and 31? Reviews?

This thread is for Flagship Lounge access questions.

A search of "LGA Admirals Club" brings up this relevant thread that's just few days old:

I have yet to see reports that the Flagship Lounge and FFD have reopened at LAX.

Check out this thread:

I'm wondering if the delay at LAX had to do with the labor dispute at the food service company (HMS?) which services the AC and FL there. And which seems to have gotten resolved around Christmas time. But I'm hoping for an opening sometime this month (as rumored) given that I'll be flying LAX-MIA-LAX at the end of the month. As well as hoping for my upgrade to clear, of course.

BTW, it's still the same rule for access: You just have to be flying in J (or F), it doesn't matter how you got there (i.e. paid/award redemption/complimentary upgrade/op-up), correct?

Access to JFK Flagship Lounge w/ Admirals Club Access?
 

Hi there,

I'm a little confused about the access criteria for the JFK Flagship Lounge. I'm Platinum on AA with Admirals Club access through a credit card. I've been to the Flagship Lounge in JFK once, before a flight to Europe. I had thought that I had access because of my Admirals Club membership, but I'm realizing now that access is tied to an international itinerary, and I'm not sure if I'd be able to get in if I were flying domestic. Can anyone advise? (Also, would anything change if I got upgraded to First on my domestic flight?)

In general it is best to research airline operated lounges in the airline's forum. I would start with this thread in the AA forum:

I am flying Flagship First into LAX, then after a 4-5 hour layover continuing on to LAS with a friend. Is it correct that I can guest her into the Flagship Lounge, but not FFD?
