But the allergic should take note: No airline can guarantee a peanut-free environment for the simple reason that none will act as Peanut Police -– none will prevent passengers from bringing peanuts onboard. And so many do (confession time: I have to admit that one company's Hot & Sweet peanut snack mix is mighty tasty). And snack packs aren't the only products that can be loaded or laced with peanuts: You can find them in candy bars, muffins, cereals, egg rolls, even chili.
Face it. Banning peanuts on planes is simply impossible. We can't even get the bulk of the aircraft passengers to turn off their cell phones.
For allergy sufferers, information is power, and there's a lot out there. Just Google "peanut + allergy" and you'll find more than 700,000 entries, not to mention numerous worldwide news accounts of the phenomena (I just read one over the weekend from Iran's Tehran Times).
Ultimately, this is one of those situations where fliers will simply have to take responsibility: Can you or your loved one fly in a peanut environment? Only you and your doctor can answer that question.
But there's no reason to fight about this. A peanut allergy is hardly a moral issue, or even a political one.
Besides, as we all know, there's always something to worry about; one of my commenters noted that he was allergic to pretzels!
Allergy sufferers have my sympathy. But my focus remains on the huge challenges facing the airline industry and how they're meeting those challenges, for now anyway, with terrific new airfare sales -- that most of us who can would do well to take advantage of.
