Yes, first-class passengers have lounge access to take a rest or have a hassle-free wait during the boarding time provided by American Airlines (AA). It's optional if the flyer has arrived early; they can use it, but otherwise, there's no need for that. However, lounge service is available for American Airlines First Class passengers at AA domestic airports. To get to know more about it, visit the AA official website or read the FaresFirstClass blog mentioned.
