Peanut allergy in-flight

An unknown but probably significant number of airline passengers are allergic to peanuts. Reactions can be mild, moderate, or severe (life threatening). Because peanuts are sometimes dispensed by flight attendants on commercial flights, there is public concern that passengers are at risk of an in-flight allergic reaction. Although there is little in the medical literature to substantiate this concern, there are anecdotal cases of inflight allergic reactions to peanuts from ingestion, dermal contact, and inhalation of airborne peanut particles. Consequently, there are several options among which the airlines must choose in order to satisfy passenger concerns.
