Nutty air travellers and nuttier tribunal

Some airlines make overweight people pay for two seats and some airlines even refuse them outright because of their weight. Why not have people allergic to nuts, book the entire plane to themselves, nut-free?  I can sympathize with people having nut allergies, as I have one too, although it's to a different food item,  but to demand that there be buffer zones on airplanes to keep them safe from an allergy attack ?

.......This case arose from complaints by two passengers with nut allergies, an adult woman and a young girl (technically the application was filed by her mother on her behalf ). The woman suggested that Air Canada should have to make all its flights completely nut-free -- a total nut ban, as it were. The mother suggested that when it is carrying a passenger with a nut allergy, Air Canada should have to make a cabin-wide announcement telling all passengers that no one is allowed to eat nuts or products containing nuts; she also suggested the airline should refrain from serving almonds in business class (as is current practice), even if the passenger with the allergy is seated at the other end of the plane..........
