This is what I found in the 3/25 AA press release:
Any ticket purchased from March 1 at 4:30 p.m. CT and April 15, 2020 at 11:59 p.m. CT will not incur change fees prior to travel.
This is available for any of American’s non-refundable published fares.

I suppose it is open to interpretation whether a web special award is a published fare.
