I second this... thanks for the definitive answer!

Now, for another question, if you don't mind. If I'm traveling and a guest takes me to the airport, can I get them a guest pass for security or it easier to just get a refundable ticket? Since the heading of that line is "non-traveling PC members", I could see where an agent will not let me get a guest gate pass since I'm actually traveling.

It would be so much easier if CO actually published these benefits for PC members...
