For years we tried to use our onepass miles for award travel from Europe to the US for my in-laws without success. Continental NEVER had anything from any European gateway, though they occasionally had partner award availablity on a convoluted routing. That said, last December we were able to book two 35K awards from LAX to Honolulu for travel around Easter. CO had several dates available and we didn't really have a problem. Delta, on the other hand, had NOTHING the whole month.
