Cheap airline seats

From The Age:

Obese have the right to two seats: court
Canada's largest airline is trying to figure out which obese and disabled passengers will be eligible for additional seats at no charge after the country's Supreme Court rejected an appeal by the airlines.

The Canadian Transportation Agency issued an order last January requiring Air Canada and other domestic airlines to make additional seats free to disabled or obese passengers who need extra room.

So, can I get a fat friend to book a seat and then sell it to me and Mrs Whitey? A new avenue for half price travel.
