OK so I am going to look into transferring my miles in CO. Last time I went on the CO website they said 75K/150K economy/business each way for travel to TLV.

How do I use CO points for UA? If I transfer to CO can I use any star-alliance member?? I know these quesations may sound really bad but I'm very new to all of this so I need a little more guidance?

Is the best way to find flights by calling the airline or searching online?
