Benefits for Authorized Users?
 

I'm interested in finding which cards have the best (if any) benefits for the authorized users? I'm having trouble searching because all the threads are talking about impacts to auth users credit scores, etc, etc.

What I'm looking for are the cards that give some benefits such as free bag, discounted flights, etc. My parents don't want to play the CC game, but I was going to add them to some of my cards if they could get some benefits.
