I just called CO to see about upgrading a flight on America West. I have not been able to use any miles for years. Every time a different excuse. Anyway I go through the entire process and they ask me for a pin number. I nearly blew a gasket! I have not used my account in years. I thought the pin code might have been a number I created. It was not. They created the pin code. I asked for a supervisor. I had to be persistent to get them to reserve the seas and mail me this pin code. I asked what the big deal was. The pin code is for my protection. I cant believe it is necessary when my other airline accounts do not require one. She told me it was for my protection. I am using miles for myself. I need to show tickets/etickets or otherwise plus ID to board the plane. What protection is this. I told her that Continental was voted the number one ff program. I dont get it. If they want some pin code thing, it should be one that I assign not them anyway. Any other thoughts on this. Rob
