I refuse to call the regular Delta phone # for assistance any more. I have been hung up on numerous times (I am a polite person on the phone - just am usually trying to get a lot of things lined up for my family flights etc). They have also gotten the wrong flights & wrong names (and I spell everything out phonetically). Last time after the lady gave me the confirmation number she just stated "I can't hear you any more am hanging up now" because I wanted her to cross reference other reservations with seat assignments (more work). I now just call the delta premier line under my spouse's diamond level status and have perfect, wonderful help.

Also a side note - you have 24hrs to cancel a flight after booking over the phone with delta for no charge. The flight info will appear within a few minutes of paying on the website under your delta FF number - so you can check it there...
