United Airlines faces backlash from passengers over mistreatment on flights.

Singer Jessie James Decker criticized United Airlines after her pregnant sister was allegedly humiliated by a flight attendant who made her clean up spilled popcorn on her hands and knees. Decker's sister was traveling alone with her two young children when the incident occurred. While some criticized the parents for not cleaning up after their children, others questioned the airline's customer service. United Airlines responded to the incident and said they would handle it internally.
