Canada's six NHL teams have been scrambling to find alternative travel routes since it was announced that the U.S. Department of Transportation was banning Canadian charter planes from flying between two U.S. cities.
Not the most serious issue facing the US and Canada. And the ban has been caused because the teams did not follow the rules set down that only players could be transported between two US points, a process called cabotage, not generally permitted by non-US carriers but Canadian NHL teams had an exemption that they allegedly abused. The issue should be fought out in the courts, not between heads of government.
