We have friends that go with us . And they always bring mini bottles . They have never had a problem . Don't know if they are just lucky or the airline just doesn't care .
But what is this world coming to !!!! No smoking on a flight ..... Now no drinking !!!! ( Before someone takes my head off .... The no smoking was a joke .. LOL )

If your motto is ; If at first you don't succeed......
Maybe it would be best not to try sky diving !
