Thanx for the info! I assume then, that since my wife will not have qualified for Silver Elite mileage for next year by 12/31/00, she will still get the mileage bonus for travel on CO through2/28/01?

In addition, I have seen threads concerning whether the Elite mileage bonus is available so long as the ticket on a codeshare is marked with a CO flight #. My question is succinct. Will a CO Boarding Pass for the flight suffice?

Thanx.
