 The appellant International Air Transport Association (IATA) is a trade association whose members include 290 airlines from 120 countries, which carry approximately 82 per cent of the world’s air traffic. The appellant Air Transportation Association of America, DBA Airlines for America, is a trade association which brings together passenger and cargo airlines based in the United States, whose members transport more than 90 per cent of US air passenger and air cargo traffic.

With the exception of Air Canada and Porter, headquartered in Canada, all of the other appellant air carriers are foreign air carriers.
