On February 15, 2023, I kindly approached the crew on entering Lufthansa flight from Munich to Manchester and explained that I have a severe nut allergy. They literally did not respond. I then asked whether they sell nuts on the plane. They said yes, we sell cashews. I asked whether there would be an option to refrain from selling them during this flight and they said no.
I went to my seat and reflected on this, not satisfied with their first response. I asked again whether they could make a PA announcement and the flight attendant went away to check with her superior flight attendant and the answer remained no. They said they didn’t want the liability for it and couldn’t stop other passengers eating nuts. No amount of explaining was going to change this issue.
