does anyone know if I purchase some booze @ LAX will they allow me to take it on my NRT-HKG connecting flight? Layover is 1hr+ and checked bag isnt being claimed @ NRT as Im connecting onward on UA to HKG immediately.Flying UA LAX-NRT

Ive been asked to bring someone some DF back with me and no sense buying it if they will take it away from me @ NRT. Last I remember NRT,HKG and SIN were more $$ then LAX, but I will be connecting @ NRT both ways to/from LAX
