Ridiculous Platinum Customer Service from Delta
I have also been experiencing extraordinarily long wait times with the US Platinum Customer Service desk. Most of the time it's 50 minutes or so, but I've had to wait over an hour and a half for a call back.
I saw a suggestion on this site to call the Korean line, so I did. Sure enough, I waited no longer than 2 minutes for a callback.
Delta, you'd better get your call bank situation fixed. I'm not happy, and I'm sure that a lot of other people are not happy as well!
