Yeah, I'll try and get some sense out of Manchester Airport tomorrow; I think they're likely t be the alpha and omega of my potential problems.

They really should allow you to keep it as part of your carryon luggage.
Well, you'd think so, but security at UK airports is SO tight now, I just don't know.

TBH, the main reason I ay end up having to leave it behind (even though I really, really need it!) is the insane cost of insurance for the darn things.
