CALGARY — Despite an economic slowdown in Alberta and a weak Canadian dollar, WestJet posted record third quarter earnings of $101.8 million, up from $85.4 million last year.

“We are very pleased with another quarter of record financial results, as we improved our return on invested capital and operating margin while leading North American airlines in on-time performance for a second straight quarter,” said WestJet President and CEO Gregg Saretsky.
