Subject: Re: airlines idine program
Hello Mary,

You certainly aren't supposed to get Idine (now Rewards Network) credit for two airlines with the same credit card. (Some people do have different credit cards set up for different airlines.) If you don't mind the risk of getting credit once on the wrong airline, you could try it once and see what happens. If you can access your AA profile online, you can see if that card is still there and you can remove it if you want to get UA credit.
