Is the free checked baggage allowance from the MP Explorer credit card supposed to show up on my reservation on united.com?

I booked for a party of four and it still shows $25 per bag. or does this get sorted out at the check-in counter?

Also, one of the party is an authorized user on my card.

My understanding is that the cardholder and one companion in the party is allowed one free checked bag each, and as far as I can tell an authorized user is also entitled to one free checked bag as long as s/he is a member of the traveling party (at least this is my interpretation of the FAQs).

Does that mean we can get three free checked bags per flight?

Thanks!
