All this talk about call signs only causes folks to lose focus on the real problems with the company.
Livery, call signs, DOH, US West profitability, etc distracts from the simple fact this product is unusable. Keep the discussion on Shares, working conditions, service and management failings (the call sign does not prove to me anything about Tempe good or bad). Parker continues to run the company and people here discuss the color the outside of the airplanes. Keep fighting the good fight folks, but there are more important things than the call sign to us customers.
