I know there might not seem to a bright side to this story, but at least she didn't breakout being in the same room as the nuts (or touching them).
On a reality TV show about airlines, this guy was having a fit. He was extremely allergic and requested that no one in a certain amount of rows around him be served peanuts (due to allergic reaction to the peanut dust). Well he was flying Southwest and they don't have assigned seating so I guess you can see where this story goes. He was so upset. he had to use his epipen on the plane
