The requirements to provide basics of life to a guest (known as the inkeeper rule) such as air, water and sanitary facilities was just too onerous for the airlines. So they sued, and they won. All of us whiny passengers are just going to have to put up with it, so sit back, shut up, and don't expect anything from the airlines.
The funny thing is, that if a prisoner is being transported on one of the planes stuck out on the tarmac, the prisoner could sue. Because it would be court ordered transport, this would certainly fit a violation of the cruel and unusual clause.
The paying passengers? Well, ya pays your money, ya takes your chances.
