All AA A321s are new and none have been retrofitted in any way. The aircraft scheduled for this flight is the standard domestic A321. There are 16F seats (which I find have less pitch than the rest of the AA domestic fleet) and the whole aircraft is equipped with AVOD. IMO this is definitely NOT worth an SWU unless you won't be using it before it expires.

Please be aware that this is not the Transcon A321 with flatbeds in F and J, just a typical domestic configuration.
