This was all meant to be a learning experience before we start for real. My wife flew separately from me and I learned that even with the Amex Delta Reserve authorized user where we pay an extra $175, she still doesn’t get a free checked bag or get on the upgrade list if she doesn’t fly with me.
The only thing she gets is Delta lounge access.
We also over packed and our luggage was over 50 pounds and we had to pay $130. So I just ordered a portable luggage scale from Amazon
