We flew basic economy, round trip, Philadelphia/Orlando in January 2020. We found a great value in booking 2 seats, and used miles for the third seat. Both flights, American 688 from PHL, and American 1848 to Orlando were on time, flight attendants were friendly.
Basic economy seats require seat assignment either at the airport, or 24 hours before flight time. On the return flight, we were all in the same row, and two of us were seated together.
No complaints! And overall, we American accommodating, and often running on time.
