These birds have been loaded into the schedule. Unsure of the starting date, but seeing them on MIA-SFO in April. As expected, and confirmed by the seat map, they have not been refit and will feature Alaska's seating arrangement (https://www.aerolopa.com/as-32q), but with renumbering to align with MCE starting in row 8. There are only 4 rows of first, along with 4 full rows of MCE (8-11) and exit rows at 12 (ABC EF, with crew jumpseat in 12D) and 25 (BC DEF, with crew jumpseat at 24F, and 26A (which is marked as preferred, not extra, despite the missing seat)). The only visible difference in the schedule is in the seat map, they are still designated as 32Q on EF and 32Q-Airbus A321neo on AA.com.
