Hello. I am looking at taking a flight from CLT to LAX on the Airbus A321 with AA. Seat guru is showing this flight as being a 3 class TransCon plane but when I go to book the flight, AA shows it as a two class. First class on the three class flight has lie flat seats while the 2 class has standard domestic first class seats. Are there any flights from CLT to LAX that offer a 3 class config or is Seat Guru completely wrong?
