During a recent trip, I read that AA has changed the carryon policy that if I were to buy the basic ticket, I can't put the carry on in the overhead bin. I have booked a reward ticket, can anyone let me know how can I find out whether I can put the carryon luggage in the overhead bin? I had looked at the ticket and was not able to find out. If I can't I may have to buy a smaller carry on. TIA
