Mixed Class Flight - Baggage???

[teacherman]

We can save some money by selecting - AA (dtw-mia  economy class) and (mia - scl  business class) vs business class on both flights.  It would be the same on return (eze - mia  business class and mia - dtw economy class) vs business class on both flights.  IF we decide to do this, changing our current booking on FlightEase, will we have baggage fees?  Or since we are on business class for each international portion, are the fees waived?  Would we still get to use the AA lounge in MIA and EZE?  If we do this, it would also be all flights on AA vs one of the international flights on LATAM, which we currently have.  Any advice/information is welcome.  Thank you.

Can’t speak to the baggage issue but as long as you have a same day boarding pass for business you will have lounge access in MIA and EZE.

From my experience (but not on AA), your Business Class ticket's baggage rules will take precedence and no luggage fees ought to be charged for two pieces of luggage.

You will not have bag fees and as long as the flights are on the same ticket, you'll have lounge access everywhere, although you'll have to show them your business class boarding passes (or show them the e-ticket receipt) in DTW on the way south and MIA on the return.
