However, people do move around on the aircraft. There are only a few loo's, people touch seat backs as they walk up and down the aisle, the FA's pick up the trash, which would include the peanut packets, and then interact with the peanut allergic pax, etc. Way too many ways for the peanut residue to spead to the peanut allergic person.
There is probably peanut residue on or around every passenger seat in economy class on flights that have served peanuts rather recently.
