* Traffic up 4.4 pct, capacity up 4.5 pct (Follows alerts)
Dec 5 (Reuters) - WestJet Airlines reported slighly emptier planes in November, data showed on Monday, as capacity increases at the carrier outflanked a rise in demand.
Canada’s second-biggest airline’s load factor — the percentage of available seats filled with paying customers — fell to 77.6 percent last month from 77.7 percent in November last year.
The low-cost airline said revenue passenger miles, or traffic, rose 4.4 percent to 1.34 billion year over year, and capacity, measured in available seat miles, was up 4.5 percent to 1.72 billion over the same period.
Calgary-based WestJet shares closed at C$11.44 on Friday on the Toronto Stock Exchange. (Reporting by Maneesha Tiwari in Bangalore; Editing by Gopakumar Warrier)
