They are 100% retiring the 333s -- https://onemileatatime.com/american-airlines-retiring-737-a330/
All nine of their Airbus A330-300s, which were delivered to the airline in 2000-2001; the airline will maintain their fleet of 15 A330-200s
AA accelerated their 787 orders and shifted the 777-200 to CLT. The 332s may end up in CLT or PHX once PHL gets the rest of their 787s.... but the 332s are only sticking around for a few more years.
I do think flying will recover ~60-70% towards the last quarter but agree that only some of the fleet may see the light of day. All of my business travel is still on hold until late fall at the earliest and I'm not alone there, nor is my company.
Wouldn't be surprised if you see some weird 332 usage (PHL, SFO, LAX, ORD, SEA, DFW <---> CLT). Consolidated flight schedules for the widebodies to make it economical. It's not unusual to see wide bodies on these intra-hub flights in the winter. All of the E-190s are gone too so 319s/321 shifts are up to work on as well. CLT <---> MEX is a 319, for instance, and a 321 can probably serve that route when they shift the 319s to the 190 markets.
