I have only had this problem once in an AA flight. I have a very nice Dakota rolling suit case. For whatever reason, the AAgent in LAS must had had a bad day and stated I had to check it in.

The bad did not fit the sizer [wheels], but yet EASILY [as the other poster stated] fits in the overhead. I stood the my ground and the supervisor allowed it, but yet five years later I am still upset.

OTHER SUBJECT ----------------

My Dakota bag weighs 10 lbs empty. This has caused me serious grief in Australia and NZ where the 'weighing spirit' is very alive and where they only allow 15lbs [a ridiculus amount when the airplane mfg rates the overheads for 80lbs +] and the rest of the 'competitive' world has a 40lbs standard.

I am for following the rules, but sometimes the AAgents use their power indiscrimately. Everyone knows how a standard rolling suit case looks and that they will fit in overheads.

OTHER SUBJECT -----------------

I think that the more generous carryon weigh of AA and domestic AA carriers is a competitive advantage over other international carriers for the normal business traveller. As stated above, I can't see how a business person can do a multi day trip on 15 lbs.
