I took a flight inside Mexico (Mexico City to Oaxaca) recently and the in-flight service snack was bagged peanuts. I was so amused, it was almost shocking to see. And, good news, no one died, but I assume if it was on a plane in US there probably would've been a strong emotional reaction by at least one person. It's good to know that the "Airborne anaphylaxis" is not a thing.
