Legal ruling could see introduction of airline 'fat tax'

The ruling, made today by the Court of Appeal, could also prevent passengers with a disability from seeking compensation from their airline if they receive unsatisfactory or inconsistent treatment during a flight.

In the cases of Christopher Stott v Thomas Cook and Tony Hook v British Airways, it was ruled that key elements of Britain’s disability and discrimination laws do not apply once passengers have boarded an aircraft.

The cases involved two wheelchair users who sued their airlines after they were unable to sit next to their carers on board a flight. Both subsequently suffered “embarrassing” incidents.

But both cases were dismissed after the court ruled that the Montreal Convention, a framework of international rules and regulations on air travel, should take precedence over British law.

Wouldn't that be true in the US as well? Don't international treaties take precedence over US laws and regulations?
