I was flying from New York to Florida when the attendants began handing out mixed nuts. The woman sitting beside me immediately said she was severely allergic to nuts. She refused her packet and started complaining that the airline should have recorded her allergy in their system.

The attendant explained that her medical form only listed an ingestion allergy, not an airborne one.

She insisted that this difference didn’t matter and that nuts shouldn’t have been served at all. Then she turned to me and told me not to eat mine.

Everyone around us had an open plastic cup of mixed nuts, so I replied that I wasn’t sure how me eating them—or not eating them—would change her situation. She said it was simply a matter of courtesy.

I explained politely that I needed to eat something in order to take my medication, but I offered to move to the back of the plane to do it.

When I came back to my seat, she said nothing—just sat silently, staring straight ahead. Ten minutes later, I froze as I saw her press the call button. She told the attendant, “That’s her.

She knew I had a nut allergy and ate them anyway.” I was stunned.

“What?” I said. She repeated herself, louder this time: “She knowingly endangered me.”

The attendant’s expression turned serious.

I was instructed to remain in my seat for the rest of the flight. When we landed, airport security met me at the gate.

I missed my connection and spent several hours being questioned.

No charges were filed, but a warning was added to my record. By then, the woman was long gone. I had to buy new tickets and wait hours for the next available flight.
