One of the worst check in experiences at PHX, but very consistent with poor US Air check in processes across the country. It is quite obvious that the layout designer and process engineer responsible for the check-in "corral" have zero practical experience in queuing theory and capacity planning that strives to remove bottlenecks not exacerbate then. The check in in experience is poor and an in effective use of US Air personnel, which undoubtedly impacted my high ticket price.
