I was speaking at a conference in Reno last week and for some reason, I found it difficult to get there. My flight plan required me to change planes in Phoenix. The only times I have been to Phoenix were also to change planes, and both times my planes were either delayed or connections were missed due to late arrivals. So I have always tried to avoid Phoenix.
This time, it was worse. My plane arrived in Phoenix no problem, the board said everything was on time, so I stopped off for a quick dinner. I then noticed that my flight had disappeared from the board -- no indication of anything, no announcement. It was cancelled. The original plane had mechanical troubles in Washington and its replacement also broke down. So for the first time ever, I spent the night in Phoenix. I only saw what you could see from the hotel shuttle, the hotel was in Tempe and not much was going on (despite ASU being right there).
I am sure it is a nice city, but given my experiences with the airlines, I will stay away from Phoenix if I can.
