A heads up to those flying Delta with a peanut allergy. On 10/25/2021 I observed peanuts as a free take away in the Delta bar area. Just writing you to let others to be aware. Delta does a great job on the plane but many people will have taken the free peanuts and may expect to eat them on the plane so please be vigilant. I am not sure about other lounges, I just happened to notice in Salt Lake City.
