I know you weren't responding to my post and I totally agree that it's not difficult to forego nuts for a few hours. But the question is 'where does it stop'? And why are dogs or cats an "entirely different issue"? I have a friend who is so severely allergic to cats that they usually trigger a severe asthma attack. Does that mean his allergy on a plane with a cat isn't as relevant as someone with a peanut allergy? It's not about empathy as much as it's about practicality. We're talking about early boarding to wipe down a seat -- something that I doubt very much is going to help anyway.
