Several U.S. airlines have announced cuts in service to Canadian airports in recent months due to a decline in use, but data from Flight Aware suggest that the overall connectivity between the countries has only gone down slightly in the last two years.

United dropped service from Denver to Regina last year and Delta will stop its twice-daily flights between Minneapolis to Regina, Saskatchewan at the end of July. United will also halt service between London, Ontario, and Chicago at the end of July. That means London International Airport will be without a U.S. carrier.
