When her daughter got up to use the restroom, Rafeiyan reported the incident to a flight attendant, who reported that the unwieldy passenger had been acting the same way towards one of the other attendants. Additionally, Rafeyian says that the flight attendants continued to serve the passenger alcohol, even though federal law prohibits boarding anyone who " appears to be intoxicated " and offering them alcoholic beverages. The same rule appears on United Airlines' own contract of carriage . Rafeyian adds that the passenger was causing other problems as well and he didn't calm down until flight attendants threatened to divert the plane.
