The standard First is based on recliner seats, similar you can find onboard Aeroflot and Turkish business class these days. I would describe that more like premium economy, definitely not First. This product is available on most narrow body jets (A320/737/CRJ). If you have international connection on business class, your domestic sector is in most cases in standard First (ie. "business class")

The second option is so called Transcon First, which is available on selected routes from east to west coast v.v. (NYC/SFO/LAX). My experience on this is based on a dozen AA flights between SFO and JFK, both First and Business. This product on AA A321T includes proper First class (1x1) and Business class (2x2) lie-flat seats, also MCE and MC (3x3). There are lots of videos and photos available. There are similar narrow body products on other US airliners as well.

IF AY plans to use narrow bodies on longer routes and want to offer a proper business class product, I see no other options than the AA style business class seating ie. 2x2 config (no free middle seats).
