This really happened to me. I wanted to fly from Pittsburgh to Miami so I called the airline's reservation service. The girl couldn't find a way for me to get there! (I had flown with this airline before from Pittsburgh to Miami) Just to be clear I said to her "Do you mean there is no way to get from Pittsburgh to Miami on your airline?" She answered "That's right."

I hung up and called the number again and got my reservation right away. FYI: Pgh to Dallas, then Dallas to Miami. I had even mentioned this to the first person I called! Unbelievable.
