Don't know whether this is the appropriate forum but...

While at DTW today picking up daughter attemted to buy CO tkt for which I had reservation. Two agents, fairly short line, but soon one agent started handling only first class. As NWA Gold suppose I could have entered first class line, but with only 3 in front of me I stayed put. My agent then took 30 minutes with the next 3, interrupted by long frequent visits to converse with a male friend outside the counter some 50 yards distant.
Finally my turn. She looked up, sighed, and then called for the next first class passenger. I pointed out that that would leave no one for the other passengers, but she was unmoved.
So I left the line and bought a more expensive NWA ticket.

Is this really CO policy?
