Although being CK for awhile, I just flew my first AA F transcon SFO-JFK and JFK-LAX flights on the A321T. The A321T F seats and set up are my favorite seats out of the AA configurations. Large footwell, wide shoulders for sleeping, and a wide aisle. 1-1 set up is nice too. Sad to see potential plans to take the A321T F class away in the future, and secretly wishing they would use these birds for LAX to HNL.
