I also posted this on a separate thread. Not sure if it is a CO.com problem or something bigger:

"I tried making an online booking for an AF Biz award ex CGD to JNB. Standard Biz award showed availability at 110K miles RT. However, when I went to the end of the booking process, the "class" was Economy and the booking code was "X." I logged out and called the elite desk; the agent said her computer only showed "X" availability and that it was economy. She could not explain why it "cost" 110k miles nor why it was displayed as Biz on the award booking engine. Has anyone else run into this? Is it possible that "X" is simply AF's code for a OnePass Biz award and that the "economy" designation is a mistake?"
