Whereas the most realistic solution to my example might be, "the parties
involved reconfirm their appointment", I expect that public transportation
companies such as railways and airlines have specific rules to deal with
these situations. That might give us some insight what the
industrial-strength resolution could be, even if we deem it inappropriate to
implement it at the end. So if someone has knowledge in that area, I'd be
interested.
