Are there any cases where someone allergic to peanuts has died or had to go to the hospital after being in the presence of peanuts, without eating or even touching them? Is this something that has ever happened? (Even once ever?)
> Investigators concluded that the risk of exposure to peanut on an airplane stems from potentially contaminated surfaces and not from airborne levels.
So the issue isn't not having exposure via air, but "not having touched" the peanuts themselves, but interacting with contaminated surfaces.
