So I have a flight out of EZE on AA. I can access either the AA Admiral's Club or the AMEX Centurion Lounge (but apparently only the part that AMEX Plats get into). It appears that the AMEX lounge is in a different terminal from where the AA flights leave, but it also sounds like those terminals are connected. I'm assuming the AA lounge location is relatively convenient to the AA flights (but maybe not SO convenient). It also sounds like the AMEX lounge (even the lowly Plat part) is better than the AA lounge. So, given all this, is it worth "the trouble" to use the AMEX lounge, or should I just stick with the AA lounge?
