RenesPoints has also reported that a Delta tech insider says that it is a glitch.
I'm not putting a ton of credence in either of your reports, but I think this issue is far from settled.
+1 for this.
Because this has happened in the past and has been fixed, my instinct tends to lean towards this being an IT error. Time will tell I suppose. Until then, I recommend yoga and deep breathing for JohnDelta. Keep calm and realize it's not that serious!
