I was booking a CX award using Alaska Airlines miles on a Sunday night and the AS agent said that the CX reservation people in L.A. were closed for the night. I called back the next morning, which I believe was the Monday of Memorial Day.

The first few times I called all I got was a busy signal. I eventually got through and the agent had an accent but I couldn't tell you what kind. She got me my seat assignments and all went well. I suppose getting someone seats is about the easiest task out there - so I can't comment on the quality of the agent.

I wouldn't be surprised if they multiple call centers.
