Yes, you can even move to the non-stop JFK-EZE flight if that were to open up. If you wanted to change to a LGA origination or return, however, you would have to pay a change fee for reissuing the ticket.
But changing your routing between origin and destination is free of charge. So no charge for moving to the later MIA-EZE flight if that's what you want.
