Okay, I see it now! CO doesn't want to spend the money on reprogramming its computers with an award/upgrade class, like domestic "F" class. CO must take upgrade/award seats from a class of fare that it can sell as well. Z.

THUS, the asinine 30-day (or less) waitlist period for those of us who who might want to save our miles and have the "pleasurable" experience of planning an international award trip on CO.Can't take seats they can sell.

Gee...honey...let's save our miles for Zurich and plan a big vacation...I can't wait...MAYBEE we'll get our BF seat--I'm so eager that I can't WAIT to see if we clear the waitlist--CO will call one of these days, probably. Again, I can't wait! Gimmie the Z.

Since CO has replied with two form letters to my inquiry regarding any rationale for its well conceived policy, the best frequent flyer program must be giving clues so that we can surmise the rationale. It's gotta be the Z!?

Sorry. A brief (somewhat extraneous) catharsis as my wife and I plan our vacation trip of lifetime--I wish I had AA miles.
