I have an AA codeshare award STL-MIA-DUS in business for 2 passengers, my guess is that we are allowed 4 checked bags (but we only have 3 to check).
Returning DUS-MIA-STL we're in coach, I think we get 2 checked bags and have to pay 150 euro for the 3rd bag.
I think we get nothing for my being OW sapphire.
Right?
