Forgive me for not having the references to back myself up; however, there was a study done on different allergens and it was found that peanut residue, particles, and dust spread like no other food out there with the exception of tree nuts which do spread just as much. When a person opens a bag of peanuts there is a good amount of peanut dust that flies into the air. There is also a good amount of oil that gets on the fingertips or the palms of the hand. The study found that wiping does not eliminate it off of hands, chairs, tables, desktops, etc. They actually had to use soap and scrubbing to eliminate residue. Handywipes, Wet Ones, etc don't work. So, one bag is not a big deal, but the majority of the plane passengers opening their bags, residue flying in the air, people touching their seats, tables, and bathroom door knobs all pose a some risk--it is different for each child. Fortunately the percentage of those who have the "smell reaction" is small but still there. I would say that the percentage of those who have the "smell reaction" to other allergens is equally as small, but let's face it--we don't have the whole plane eating scrumptuous, aromatic melon (I haven't had THAT on a plane since about 1980), nor do we have people opening cans of smelly tuna or noshing on shrimp salad.
I understand your argument here with "when will it stop", but the fact is that the peanut is unique in its ability to "materialize" into the air and circulate--much more so then other foods. Couple that with the amounts that the airline would give out and it's a problem. Seafood is a HUGE allergy, probably bigger than peanut, but since its use is so limited on planes it has never become an issue.
