CALGARY — WestJet reported May traffic results increasing 7.2% with a load factor of 79.2%. Capacity, measured in available seat miles (ASMs), grew 1.3% over the same period. The airline flew more than 100,000 additional guests compared to May of 2011.

“We are very pleased with this month’s load factor and forward bookings are showing continued strength as we head into the busy summer flying season,” said WestJet President and CEO Gregg Saretsky.

WestJet recently implemented Korean Air as its sixth codeshare partner and has launched seven new interline arrangements thus far in 2012, bringing a total of 24 alliance relationships to connect its guests throughout the world.

In May, WestJet inaugurated new daily service to Chicago’s O'Hare airport from Calgary and Vancouver and earlier this month the carrier started service between Toronto Pearson International Airport and New York’s LaGuardia airport.
