Thanks Jo and V - I'll do my best not to let my team down!

And Sarah, thanks for the DVT reminder - hydrating is a big deal for combating altitude issues, and for the DVT risk, so I will be drinking water non-stop both ways. I'm going business class (thanks to years and years of saving up AA miles - I figured I'd better use them before they completely lose their value) so moving around should be easier than wedged in back in coach.
