Airline's May capacity increased 15 per cent over May last year

CALGARY, June 6 /CNW/ - WestJet (TSX:WJA) today announced its May load
factor of 80.0 per cent, exceeding May 2006 load factor by 3.1 percentage
points and setting a record load factor for the month of May. This is the
fifth consecutive month WestJet has produced a record load factor. May results
include a 15 per cent capacity increase as measured by available seat miles
(ASM) and a 20 per cent increase in revenue passenger miles (RPM).
"We are pleased that every month in 2007 has produced a record load
factor," said Sean Durfy, WestJet President. "What makes this more impressive
is our year-to-date ASM growth of 18 per cent. In May, we transitioned a
further 15 per cent of our capacity to domestic routes in order to meet summer
demand. Quarter-to-date revenue per available seat mile (RASM) is slightly
positive over last year."
"Our WestJet owners continue to deliver our exceptional guest experience
and I thank them for their continued efforts," added Sean Durfy.
