I've seen lots (and lots and lots...) of postings about this 'subject but I can't recall having seen any one deal with one particular situation - although squatting seems to be favoured one!
What happens if you get the dreaded affliction within the last 12/24 hours before your plane departs?

Does one stay locked onto a toilet and catch another plane; which of course may not be all that easy or what???
I am just waiting for a flood of information!!!
