CALGARY — WestJet is reporting August 2015 traffic results with a load factor of 84.6%, down 4.7 percentage points.

Revenue passenger miles (RPMs), or traffic, increased 1.7% year over year, and capacity, measured in available seat miles (ASMs), grew 7.3% over the same period. The airline flew a record 2.0 million guests in August, a year-over-year increase of 2.3% or approximately 44,000 additional guests, and achieved an on-time performance rate of 84.0% in the month, an improvement of 6.3 percentage points year over year.

“We are pleased with our continued traffic growth as we welcomed almost two million guests on board in August, setting a new single-month record even as the Labour Day long weekend shifted out of August this year. The movement of this busy travel period into September contributed to the year-over-year decline from the all-time high load factor reported in August last year,” said WestJet President and CEO Gregg Saretsky.
