Ms. PUCCI:

If you Google "AA schedule change policy," you should find a link to a PDF of AA's March, 2022, policy. Maybe I am misreading the policy, but for schedule changes that exceed 60 minutes, it seems to indicate that the passenger may be re-accommodated in the same cabin on a flight that departs within 24 hours of the originally scheduled departure time. If the same fare inventory is not available, the passenger may be booked into the lowest available fare inventory for the same cabin. (See pages 7 and 8 of the PDF.) I assume that "within 24 hours" means up to 24 hours before or after the originally-scheduled departure time.

Hope that this helps.
