Well, according to the AAAAI, "airborne peanut allergens" are not actually a thing.

I'm all for consideration for others, especially when crammed into a tight space for hours on end, but once we get into the realm of purely psychological effects, where do we draw the line? For example, there are people that are absolutely convinced that my phone's electromagnetic radiation will cause them discomfort, yet in-flight Wi-Fi is a thing.

To be clear, I'm totally on board with limiting common allergens in airplane food, but please let me eat my own peanuts in peace instead of further facilitating mass hysteria.
