cordelli, thank you for your suggestion. I couldn't remember which credit card I assigned to what airline. I went to the idine website and input my mileage plus Firstusa card. Invalid card. I was requested to call customer service, and after a few minutes, had everything straightened out. She told me to go to
www.mpdining.idine.com to create a profile for my UA account, using my MP FF number as my username. She also looked up my NW account and we updated the cc info on that, too. My CO account had been cancelled by me two years ago. I asked her to send me a new booklet, and she told me the restaurants are the same for UA and NW.
Everything was pretty easy to do. No long wait, and the website was okay to navigate on. I'm ready to go!
