Peanut allergies are very common and are often very severe in that if a sufferer has close contact with peanuts, they may suffer anaphylactic shock which can be fatal. In flight, in the occurrence of anaphylactic shock, the sufferer is hundreds of miles away from the nearest emergency hospital to receive vital treatment. Therefore, I believe that peanuts should not be sold in flights and should be on the list of banned items. This will help to prevent anaphylactic shock and prevent holidays from being spoilt!
