Looks like your FA didn't have a clue. There are no A321s from 1985.

The maiden flight of the Airbus A321 came on 11 March 1993, when the prototype, registration F-WWIA, flew with IAE V2500 engines; the second prototype, equipped with CFM56-5B turbofans, flew in May.Lufthansa and Alitalia were the first to order the stretched Airbuses, with 20 and 40 aircraft requested, respectively. The first of Lufthansa's V2500-A5-powered A321s arrived on 27 January 1994, while Alitalia received its first CFM56-5B-powered aircraft on 22 March.
I've always thought the pmUS A321s were fine in Y for the seats, and they've always had WiFi in the last couple of years I've flown them. US's mainline fleet went 100% WiFi some years ago.
