Tell your friends to make up some of these mai tais, and have them just before going through security (recipe is for one drink):
1 oz. Okolehao (dark)
1 oz. Myer's Planter's Punch rum
1 oz. Orange Curacao (Hiram Walker)
1 oz. Lemon Juice
1 oz. Orgeat syrup
I guarantee you it will be better than anything they can have on any airline.
