Calgary-based WestJet reported Thursday a load factor – the proportion of seats filled on its flights _ of 79 per cent for June, up from 75.7 per cent in June 2011 when Air Canada suffered a brief strike by its customer service agents.
The increase came as passenger traffic climbed 6.7 per cent from the same time last year, while capacity increased 2.3 per cent.
"Advanced bookings for July and August remain strong," WestJet president and CEO Gregg Saretsky said in a statement.
Meanwhile, regional carrier Porter Airlines reported a load factor of 62 per cent for June, down from 64.6 per cent a year ago.
"Numbers for June, although slightly less than in 2011, met our expectations, especially considering the fact that a strike at one of our competitors last year," said Robert Deluce, president and CEO of Porter Airlines.
Passenger traffic for the Toronto-based airline increased 4.1 per cent, while capacity gained 8.5 per cent.
