^agree w/ cyrille & AO. AA allows only 7 kg carry-on plus a laptop bag/handbag/ shoulder bag. If your luggage is more than 7 kg, check it in. If you do online check-in, you can modify your booking & pay less for checked-in luggage. If you check it in at the counter, it's more pricey. (At least, that's the case in PI.) I flew with AA last month, MNL-TPE. Witj most of my AA flights, the gate agents were strict abt the 7 kg carry-on rule. Don't know if they're strict in Th.
