At 39,000 feet, people with nut allergies can feel like public enemy number one. Nothing can tick off the other passengers faster than a flight attendant announcing that a complimentary package of peanuts isn’t coming, because of a flier with an allergy.
Doctors say it’s highly unlikely that allergic passengers could have a reaction due to the person beside them eating nuts, but that doesn’t mean that they won’t suffer from lesser symptoms like nausea, stomach aches or anxiety. And then there is the possibility that they could have an even worse reaction by accidentally touching nut residue on a tray table or armrest (and be honest, how often have you smeared your own salty fingers on the side of the seat?) If something does happen – and there isn’t the appropriate medical care or medical personnel on board – that could lead to an emergency landing.
