American Airlines is expanding its Five Star Service, which includes priority check-in, expedited security screening and other benefits, to four new airports–Austin-Bergstrom International Airport (AUS), Nashville International Airport (BNA), Newark Liberty International Airport (EWR) and Atlanta Hartsfield-Jackson International Airport (ATL).

The new additions bring the total number of airports offering the carrier’s Five Star Service to 16. Five Star Service is available for customers traveling in a premium cabin and also includes access to the Admirals Club, an escort to their gate and other customizable experiences tailored to their interests.

“Continued adoption of our Five Star Service demonstrates the value our customers place on a streamlined travel experience,” says Janelle Anderson, vice president of global marketing for the carrier. “We know the onboard experience is just one part of our customers’ journey. Through continued investments in renovated Admirals Clubs, new Flagship Lounges and personalized on-the-ground experiences, we’re making strides to enhance the level of care we provide from curb to gate.”

American is also investing more than $200 million in the premium travel experience with new Flagship Lounges at John Kennedy International Airport (JFK), Los Angeles International Airport (LAX), Miami International Airport (MIA), Dallas Fort Worth International Airport (DFW) and Chicago O’Hare International Airport (ORD). The lounges provide customers traveling in Flagship First and Flagship Business with elevated food and beverage options and space to refresh, unwind or work before their flight.
