So it sounds like some of the aircraft that I booked on AA in 2020 in First were the older Oasis, since there was virtually no underseat storage in First? I usually have no problem storing my computer bag underseat in either Coach or F on any aircraft, but on these planes there was virtually NO storage in front of my aisle seat and the space between the two seats would not fit my bag either; again that was WAY too small to get the bag under the seat.. I hope I don't run into any more of these old Oasis aircraft!
