Delta Airlines-Are They Nuts?

While on the way to and from Las Vegas this past week, I was amazed that Delta Airlines served peanuts as part of an in-flight snack. Given how sensitive our society has become to those with peanut and nut related allergies, one would think that they would go with something more palatable to the general population. As an example, our sons attend a pre-school and camp where there is a very strict ban on any type of nut product from being brought into the building. So I am sitting there thinking as the flight attendants come through what would happen if a passenger went into anaphylactic shock at 30,000 feet? To be fair, they also offered cookies as a snack, but I know that some people have a reaction from even smelling peanut or other nut laden products. However, in this litigious society we live in, I am sure that they have consulted with both legal and and medical experts on the subject. This is not to mention the fact that it was surprising that this snack was still provided free of charge. Am I missing something here? Thoughts?
