Your PIN code is necessary so someone else cannot steal your miles, or at least it makes it harder to do. Without it, anyone who glanced at your card, or got your number any number of ways <like off of PC Luggage Tags> could book tickets with your miles.

By the way, welcome to FlyerTalk. Since all you have done since you started with FT is complain about how much you dislike CO, I hope things improve for you, or you find another airline you like better.

Hell hath no fury like that of an elite frequent flyer in coach.

I can give up getting FF miles anytime, sure I can, I am not addicted, I swear.
