Air Canada has sued award search website Seats.Aero in Delaware court for pulling award availability from its website. They claim (1) trademark infringement for use of its marks, and (2) violations of the Computer Fraud and Abuse Act for accessing its systems without authorization.
There may be a real problem for Air Canada here, but their legal claims appear weak – and certainly bad from a public policy standpoint. They have deeper pockets, though, and sometimes that’s enough to prevail.
