Yes, this is what AA calls valet bags, not gate checking. They apply a red tag to the bags and return them on the jet bridge at the end of the American Eagle flight. It only happens on Eagle planes with overhead bins that can’t accommodate standard rollaboard bags (ie the CRJ 200/700/900 and ERJ 135/140/145 as well as most or all turboprops). On Eagle planes with larger overhead bins that can accommodate rollaboards (E170/E175), they do not valet tag but instead check to the final destination like on mainline if you’re unable to fit your bag on board.

(I’m pretty sure AA doesn’t still operate all of the types I’ve listed, but I’ve lost track in detail.)
