Please educate me. Currently Plat Pro but will drop to Gold in 2019. Interested in Booking a one way award ticket for daughter and I. CDG-MIA in late May. AA Saver economy is available now but not a Business seat which I prefer. If I book now for both my daughter and I to secure better seats due to my status, if a Business saver opens up closer to the date, can I "change" to the better class without a change/cancel fee? If no fee, can I just change my seat and leave my adult daughter in coach? I know when I use to purchase tickets for two of us on one PNR and request and upgrade using miles and copay, I could not split the PNR if only one upgrade cleared. Is this the same as full award bookings? If so, she is on her own.
Thank you.
