Is this a DL specific thing? I certainly have not suffered from a, "You're on an award ticket so no help for you!!" attitude at UA (and they aren't exactly considered benevolent masters either).
That said, it's sad that the airlines don't treat award pax with extra care as the award pax is the one being rewarded for his loyalty to the carrier and should be recognized as such.
ya, 'cept their attitude (all us carriers) has always been,
"Hey! We gave you something for FREE! Why would you EVER complain about any of it!?!?!?! GEESH!, Some people!"
