Thank you Rutan16 for your wonderful swift reply. I don't like saying this but I did say we are travelling Wednesday 8 August - sorry. John is starting to get really nervous so we are getting in touch with Swiss and asking for some kind of assistance. I don't what airlines offer these days with what is basically a mental health issue. He suffers nervousness in many crowded places and, for example, at the theatre has to go to the toilet several times until just before the performance starts. He will certainly get to know Terminal 1 toilets well at least! Thank you again.
