A passenger on a United Airlines flight was frustrated by the airline's lack of policies regarding food allergies. The video, which has over 19 million views, shows a passenger asking for an announcement of a buffer zone to encourage others to avoid eating nuts. However, the airline refused this request, stating that emailing her to inform the situation was not a solution. The airline's policy states that flight attendants are to know before takeoff if any passenger has an allergy, and passenger MK stated that she regularly checks their policies before her flight and always wears a mask in flight. The Post has reached out to both United Airlines and the public for comment.
