Owner sounds like it's Front Page Tours. I had read NWA had some ownership at some point in Champion's history.
From Champion's web-site:
Champion Air is the largest dedicated provider of charter airlift in the airline industry.
Based in the twin cities of Minneapolis and St. Paul, Champion Air currently operates a fleet of twelve Boeing 727-200 aircraft and serves a wide variety of customers that include professional sports teams, corporations and major tour package wholesalers.
Champion Air was originally formed as MGM Grand Air in 1993 by the MGM organization with the purpose of providing trans-continental air travel to the high-end customer (corporate executives, actors/actresses, etc.) at a premium price. As operating results failed to meet expectations, MGM exited the airline industry, selling this division to Front Page Tours, a packager of charter travel targeting attendees of high profile events (e.g. the Kentucky Derby, the Super Bowl, etc.) and professional sport teams. Current ownership acquired Champion Air in 1997 with a specific purpose in mind - to provide safe, reliable, economical air travel for a range of customers. While our mission has changed, our commitment to providing our customers with a high level of personal service has remained constant. The company's mission statement embodies the principles upon which the airline has been rebuilt:
"Striving to surpass the expectations of our customers by providing a superior travel experience built around safety and reliability at an economical price."
