I have the UA MP Explorer card, and my wife is an authorized user. It's our primary family card, and we like having one shared account for ease of budgeting etc. However, we both travel a lot for work, and apparently only I get the United benefits of the card, as primary cardholder - priority boarding, free checked bag, upgrades on award tickets, etc. My wife as authorized user gets none of this when she travels without me. Which is, of course, bull--why the arbitrary distinction between users, especially since either of us could have filled out the application materials?

So my question is whether there are any cards out there that grant their full travel benefits to both the primary cardholder and an authorized user (or that allow spouses to both be primary cardholders)? Could be an airline, hotel, or any other type of card. Thanks.
