Flying With Peanut Allergy

Published studies showed that severe, or anaphylactic, reactions caused by peanuts occurred on flights from ingestion of peanut-containing meals or snacks. Other reactions from exposure via skin contact or inhalation were generally less severe.

These noningestion reactions generally occurred when at least 25 other passengers were served individual packages or bags of peanuts; products that had little peanut content did not cause such reactions.
