[QUOTE=thagale]Look at the designation of the aircraft a little closer. If it's M80 or S80, it's an AA-reconfigured aircraft and there will be room aplenty. If it's M83 or S83, it's still a TWA-configured aircraft and bags will typicall have to run parallel to the centerline.

That's not true as the ex-TWA aircraft are being converted to the larger overhead bins. AA also has some MD-83 aircraft but I believe they are still listed as S80.
