The medical travel policies were revised last year, at the end of the 18^th Assembly, and one of the new features is an appeal mechanism so that, if someone is denied an escort, then it is possible for that person to fill in an appeal form and file that with medical travel and have it considered. The only hitch to these, though, and I get lots of these crossing my desk, is that people need to plan ahead. Medical-travel people work a regular day. There is an on-call function, but I find they get a lot of last-minute requests. If the person who requires an escort is denied, there is an appeal mechanism, and good planning will get a quicker result.
