As this is my first post, I just wanted to say thanks to all the members who have posted information that was both important and useful. I hope that with all my future travel I could be as helpful as many of you have been.

Now for a CO question, which I am not sure has been answered before. I will be reaching Silver Status after my next flight (No Promos - 25k actual flight miles) and know that flights after that are credited at 50% bonus miles. I was thinking of taking advantage of the BusinessFirst sale that CO has. Does this mean that that a purchase of a BusinessFirst ticket after attaining status would mean 100% bonus miles (50% BusinessFirst & 50% Silver Bonus)?

Thanks.
