I’m impressed by the speed with which American has rolled out their Flagship lounges. They’re offering a high quality business class lounge product. The LAX lounge gets busy, but while I was there it wasn’t a madhouse. Food and beverage options, as well as showers, are quite good.
While I often skip the Admirals Club unless I need help with a reservation, it’s at least worth stopping in here if you’re eligible for a snack.
