"Certain specialty tickets, including but not limited to unpublished, consolidator, group/tour and opaque fares, do not earn PQD. Additional information can be found in the PQD terms and conditions."
If they are calling your fares ineligible for PQD, then I'm with you. I would be gone, too! Not sure I would have even done them the favor of telling them why.
Stuuuu-Piiiiiid. All airlines pull boners from time to time, but UA is certainly pulling more than their share lately.
