I wonder how much irrops help they give. If all they do is take you to the UC counter where you wait in line with other UC members, then that has no value for me. (I already have UC access.)

This is one of the questions I asked them, but they never answered.

I understand that AA Five Star gives you higher priority for rebooking and that the Five Star agents assist you directly. I was hoping that UA Signature service would be the same.​​​​
