Emotional girlfriend's outburst delays flight for over an hour

An emotional girlfriend caused a flight to be delayed by an hour and 40 minutes after fighting in the departure hall, then demanding to be seated next to her partner. The HK Express flight UO559 from Da Nang, Vietnam, to Hong Kong was scheduled to depart at 6:30 pm local time on November 2, but only left the gate at 8:10 pm due to the feuding pair.
