I have updated my corporate travel profile to specify my cell number as my primary contact info, so that when Delta feels the need to let me know that my flight has been cancelled, they’ll call there (instead of calling my office and ignoring the message that says they should call my cell because I’m freakin’ out of the office on travel).
Since a similar snafu hit me when I was in the UK (in that case it was the hotel I was staying at that was trying to put me somewhere else), it seems about time to do it.
