If the flight is labeled as a Flagship Flight (3 class 321T) and if he's flying F or J, yes.

It is offered on departure and arrival as long as there's an eligible segment of the itinerary. It is also available at airports on non-Flagship segments (for example, if he were flying SFO-JFK-MIA, he could get into the FL in MIA based on SFO-JFK being Flagship-eligible).

The important thing is for him to hand over the eligible SFO-JFK BP first upon arrival to the JFK FL entrance. Otherwise, the lounge dragon may notice the JFK-DCA BP and give pushback (it should show eligible if scanned just like the SFO-JFK BP, but some staff will give pushback before even scanning it for some reason).

SFO-JFK-MIA although of course you're right you would get access......thats like a 60/40 yes/no thing right now at MIA. Especially when arriving, even off a straight transcon there have been issues let alone from JFK.

The inconsistencies never stop with AA...

Hence why I always have the web pages ready to reference in situations like this.

Yeah, I am now at the third or so level with the Admirals Club people discussing inconsistency in Flagship Lounge guesting. In one place in their website it's made clear that one guest is permitted for F passengers on transcontinental Flagship flights. And in another place, also dealing with Flagship access, it just says no guests.

At MIA, when I fly a transcontinental Flagship flight, I have always allowed to bring in one guest. A few weeks ago, at LAX, they denied me guesting under the exact same circumstances.

They are "looking into it."

While individual agents may be inconsistent, the AA policy itself is not (edit: I see you've mentioned the AA website is ambiguous and perhaps contains different information in different places, but the policy seems clear to me on the main current access page).

It's clearly listed on the AA website that passengers flying "International First" get a guest, while other customers who qualify based on class of service do not. They were correct to refuse guest access at LAX, unless you're either CK or a non-AA/AS OneWorld Emerald or Sapphire, or you were arriving from or connecting to an international F flight.

I was flying MEX-MIA-ORD in J as PlatPro and and was denied access. They said policy change and Mexico City doesn’t qualify for flagship, only admirals clubs (which I’m a member anyway). I think wiki needs to be updated

The MEX, Central America, Northern South America Flagship Lounge exception has been gone for about a year now (since April 2021). In fact, it was removed before any of the FLs even reopened. It should definitely be updated in the wiki.

From Flagship Lounge, Terms and Conditions, in the AA website:

• Customers who may access a Flagship® Lounge include customers traveling in a first or business class cabin on qualifying international or transcontinental flights....
• Customers who are eligible to access the Flagship® Lounge and who are traveling in a first class cabin or are eligible to access the Flagship® Lounge on a qualifying flight...are permitted to bring one (1) guest into the Flagship® Lounge

You're misreading the 2nd bullet point. In this case First Class on a transcon is not a qualifying flight for guest purposes. The main FL access page clearly lists First Class (international) as one guest, First Class (domestic) and all others no guests.

That's not the interpretation of the Miami Admirals Club staff. They read the language as (1) including transcontinental flights as "qualifying" flights, and (2) providing that those traveling in F on "qualifying" flights are entitled to one guest. And they allow those travelers to bring a guest as their general practice.

Clearly there is conflict, ambiguity and lack of clarity here. My initial post was intended to address inconsistency.

Yea but in this case AA has clearly defined the rules (for once) it's just the MIA agents are evidently lax in their enforcement or just not trained well. Not the first time something in the T&C's is poorly written, out of date, or just doesn't match up with what's on the main page.

I'm currently booked in economy hoping for an upgrade to business

Just a little confused now on the recent convo on Guests. On FF on Transcon I can bring 1 guest or I cant? I always thought I was not allowed and never tried. Thx.

If you're accessing the FL via class of service:

International F: 1 guest
All others: no guests

I pasted the rules above straight from aa.com.
