To answer the title question-not for me, not even close. I always get fantastic service from them. But then, I am usually calling about a missed connection in ATL, not a four hop TATL. I've had a couple of frustrating calls but they were pretty much when there was no solution to the problem (last flight of the day or everything booked) and I just wasn't ready to hear "can't help you." Never had a good suggestion on rerouting turned down, never been charged for an accidental missed flight, never paid a service fee for a rebook due to illness, even for the family, etc. Even had them proactively rebook me just because the connection was going to be close to MCT (but not under). Really it's the main thing I love about DM status--the "travel lubricant."
