The U.S. moved more aggressively than Canada to liberalize its aviation policies. With the deregulation of its domestic aviation market in
1978, Washington launched an international policy that relied on market forces in areas such as pricing and charters. In the mid-1980s, this
was followed by an“Open Skies”policy framework and the conclusion
of bilateral agreements with many foreign governments. The“Open
Skies”framework allows unrestricted routes to and from all cities in
the US and the partner country. No limits are made on the number of
airlines allowed to operate or the number of flights they can offer.
