Ok, so I am a United MileagePlus member and also hold the Chase Sapphire Preferred card. With that card, you can earn 2x points for restaurant charges. In addition, you can earn United MP points/miles by participating in this program below as long as you have your credit card on file: http://mpdining.rewardsnetwork.com/ So, I'm getting 2x points with my Chase Sapphire Preferred card AND points for charging with the card and into my MP account. NICE!!
