When you search American Airlines for economy tickets from low too high on dollars only the basic economy tickets come out in that order. If you like me prefer to fly main cabin economy it is random how the prizes are listed and it don't follow the chosen low to hight order. Please be AWARE that after AA introduced basic economy you can not search from low to high in main cabin. As a frequent flyver this is an alarming development. The airline was trying to say that it was due to my browser and this is NOT the case. Which after explaining my case to the a supervisor she agreed. Please see attached screen shoots ....
