Looks like this is another classic case of the CO and NW programs being out of Sync, this time in CO's favor. I purchased today form CO, a NW ticket, JK-SIN-JFK next May for $1120RT. I could have done KUL ($1040) or BKK ($859). I had no trouble upgrading with 50,000 miles from my one pass account. I did have CO reservations check many differnt options and it was no problem upgrading the "cheap" ticktets with Onepass miles!
