I have a long (~7 hours) connection in MIA that requires me to pick up my luggage from AA and check them into TK. Since the TK counter won't open until 3 hours prior to flight, I'm stuck with luggage. Ideally, I'd like AA to pick the bags off the carousel and hold them for me while I wait for check in to open in the comfort of the Centurion lounge. Is this something that can be arranged with AA?
