I just played around with
http://www.continental.com/web/en-US...ardTravel.aspx and learned that you can't (or I don't know how to) book just one way on onepass miles. Its 50,000 miles.
One way might be to get the Continental Airlines World Mastercard (earns 20,000 miles on your first purchase ---
http://www.continental.com/web/en-US...reditcard.aspx). That plus the 35,000 miles you already have gets you up to 55,000 onepass miles, enabling you to book a saverpass ticket to the states.
