alt Hacker News> a peanut shortage prompted Delta, then America’s fourth-largest airline, to seek an alternative onboard snack
I never knew this was the reason. I had assumed that airlines stopped serving peanuts as an accomodation to the increasing number of people with peanut allergies.
It's both. That's why Southwest stopped, for instance. Literally just opening a small bag of peanuts around people who aren't eating peanuts is enough to bring someone with a severe allergy into anaphylactic shock.
