I am using the CC on my account, the Delta Platinum AMEX. Not a miles purchase. And only purchasing one ticket. Just trying to see if someone has had the same issue.

I'm planning to call back and get a new tech support person. It's hit or miss with getting the good ones. For example, a while back, when calling the Medallion number, it started to prompt me for my Skymiles number rather than saying "Hello Rob." Agent had no clue. Second agent had no clue. I called back a few days later (to book since the web site wasn't working) and the agent asked if I had an account for a minor and the same phone number listed for him or her. I did. Removed that number and now it works fine when I call.
