I am not claiming legality, but merely that the arguments against back to back have no legal basis. I am saying that it is not amoral to take advantage of an available fare. It is moral to my personal situation, as i can invest the funds saved ini my family's financial wellbeing. It's not cheating, it's smart shopping. I am not a shareholders, and the shareholders value of my travels on any airline are of absolutely no concern to me. The airline will always charge what the market will bear and I as a consumer will buy what i can bear.
