I've had terrible luck getting upgrades to clear, but hopefully you will have more success. I have one CR-1 that expires 2/29/12. It must be used for travel on or before that date. It can be used to upgrade any one-way travel within region 1. Its easier to use for United metal, but can be used for Continental as well, although sponsoring it is more difficult on CO. Please let me know if you are interested, and I'll do my best to sponsor your upgrade. Happy Travels!
