A passenger became so angry during an argument about overweight luggage that she slapped an airline employee. The Vietnamese woman was waiting to board at Tan Son Nhat International Airport in Ho Chi Minh City, Vietnam, when the incident took place. The traveller had checked in and was travelling with just hand luggage when she was asked to have it weighed by a worker. Nguyen Thi Hang placed her luggage on the scales, and then lashed out hitting an airport worker in the face . The woman, who has been named locally as Nguyen Thi Hang, 35, was stopped by a VietJet Air employee who believed her two pieces of hand luggage weighed more than the 7kg permitted. The woman proceeded to place her luggage on the weighing scales, but in a fit of anger lashed out and slapped the member of staff in the face. The scales showed the luggage did indeed weigh more than the allowance permitted. The Vietnamese woman was set to bound  VietjetAir flight to the capital city of Hanoi . Thi Hang was flying into the Vietnamese capital Hanoi. Aviation authorities told tuoitrenews.vn that 'passengers are allowed to carry only one piece of portable baggage weighing up to 7kg with a of size 56x36x23 cm when boarding an aircraft' and that 'any excess baggage must be deposited at check-in counters before boarding.' The woman, who signed a statement admitting the incident in the aftermath, has been fined VND7.5 million, which roughly equates to £240 - much more than an additional weight increase would have cost her at the time.
