Wanted to give a quick review on my lax - jfk - lax last week, as far as lounges went.
In lax my ticket in first on the new aa planes got me into the flagship lounge, which is basically a separated section of the regular admirals lounge. Other than feeling special and going through fancy key card only doors, there's not much different, but it's much quieter and has a open help yourself bar.
Bathrooms were gorgeous. And the showers looked nice too.
