Thanks for the responses. I think AA typically uses L1.

I like to know because I like to be the first (or near first) off the plane. As you roll your eyes as I rush past you and you think to yourself, “what’s his hurry?,” know that the answer usually is “nothing, but let me go anyways; I promise not to inconvenience you.” That said, when I arrive at MSY, I can get through GE, into a taxi, and home in less than 30 minutes from when they open the door. (My record is 20 minutes on a 1:00am domestic arrival from when the aircraft door opened to when I stepped into my front door in Mid City, New Orleans.)
