It's a New York thing more than an AA thing for sure. New York imposes a 14 day quarantine on travelers from 31 states and basically every foreign country of consequence. This has shut down virtually all out-of-town business travel and most tourist travel. Even to the extent not applicable (e.g., California is not on the restricted list), Manhattan remains closed for office-type business for essentially all purposes, and suburban businesses have largely replicated that - all meetings online only.

JFK, LGA and EWR can feel nearly as empty now as they were at the depths of the shutdown in April and early May. It's a shocking contrast to DEN, DFW, MIA, ATL, CLT etc. which at least in their home hub carriers' terminal(s) can feel as busy as ever during their bank times, and in some cases busier given that a lot of restaurants, bars and airport lounges remain closed or limited service creating long lines elsewhere. (Although they quiet down a LOT between banks, which in many cases are reduced by at least half on a daily basis.)
