Human Factors
During boarding I saw the passenger consuming alcoholic beverages. I let him know that he was not allowed to do this and I took 4 50ml bottles (3 full and 1 had about 1/8 of the liquid in it) from him to serve to him during the flight. I asked if he had any more and he said he did in his carry on that he gate checked. After he consumed the 3 1/8 he continued drinking; [and] then gave me 5 more empty bottles. I asked him where he got them and again he lied to me saying they were in his carry on bag in the overhead. They were in a bag under the seat. He continued to drink. He got very loud and belligerent during the end of the flight. When we arrived I requested assistance from security. I did not want to take the chance of this passenger driving or connecting to another flight. The manager on duty; met the aircraft and took custody of the passenger. I would like to know how he got at least 14 mini 50 ml bottles through security? When deplaning this passenger could not walk without bumping into the seats. I asked him to sit in 1A until I deplaned the rest of the passengers so he could not injure himself or other. Do not allow this passenger to travel on [our aircraft].
EMB145 Flight Attendant reports that a passenger had in his posession at least 14 mini (50 ML) bottles of alcoholic beverages and consumed most of them. The Flight Attendant questions whether these were brought through security.
