I'm thinking about trying to book a major trip before British Airways revamps their program. The background: The trip would be for next Fall (Sept/Oct.) My partner and I have 310K BA miles and 150K AA miles (we also have 100K USAirways miles, though that's obviously not OneWorld.) We could do the $30K spend to get a companion award in 2012, though BA will have changed redemption by then I will be Platinum on AA as of next week We would like to travel Business Class (or better!) Our home airport is SFO We would like to visit Asia (Hong Kong, Singapore), Europe (we can land anywhere, and will then use trains to get around) and South America -- specifically Argentina -- before heading home. Is it possible to do this with the miles we have? If so, should we be focused on putting together a series of one-way awards or an around-the-world pair of tickets? And how could we use layover rules to help this process? Normally I'd focus on gathering even more miles for several months before making plans, but given the imminent BA change, I'm thinking it might be smart to lock things in now. As someone who has never attempted an international award before, let alone a complex one, I'm not even sure where to start -- other than asking all of you for advice!
