Taking 2 flights to Milan next year and wondering where would be a good program to post the miles to? US Airways is leaving to One World and with United gutting their partner award chart I'm not sure where to go. I know sometime only a percent of the miles are awarded on certain flights with some carriers depending on the class.

If it helps I'm in K class. I think I get about 9K miles each trip, taking 2.

Krisflyer? maybe Agean to get status forever? Is that still working?

Any advice would be great

Thanks
