News Releases

CALGARY, July 19 /CNW/ - WestJet (TSX:WJA) today announced that they have
reached agreement with Travelport to discontinue negotiations on the amendment
of the aiRES contract. As a result, WestJet will incur a non-cash write-down
of $31.9 million pre-tax ($22.2 million after tax) for the assets associated
with WestJet's aiRES reservation system project. This write-down will be
accounted for in the airline's quarterly results for the period ended June 30,
2007.
Sean Durfy, WestJet President commented, "As we stated in our January 10,
2007 news release where we first announced suspension of the aiRES
implementation, we recognized the potential for this one-time write-down.
Unfortunately, the possibility of implementing a future version of aiRES in
the timeframe needed to meet WestJet's requirements is highly unlikely.
"Our current reservation system has been upgraded and is fully supported
to meet our strategic plan for the remainder of 2007 and throughout 2008. All
of the key functionalities we require to achieve our objectives are available
to us. We will review our options for a new reservation system, from a variety
of companies including Travelport, to meet our strategic plan beyond 2008."
WestJet will announce its second quarter results on August 1, 2007.
