Didn't catch this before I left ORD (my original flight was delayed, reducing time) or I would have run over to B7. And I ended up on a Skype call at IAD before leaving for LHR, so didn't have time to leave C/D to get to A. Due to being sick today is the first day I've been on, and the no mouse is driving me crazy. Will ask upstairs at the exec lounge re: one being left behind. Otherwise, I'll find a place on Oxford Street & buy one there in the morning.

Thanks for the input & suggestions.

Cheers.
