The director of a southwestern Illinois airport that has never turned a profit since opening with great fanfare 16 years ago has gotten a pay raise as well as a bonus of more than $13,000.  The Belleville News-Democrat reports Tim Cantwell oversees MidAmerica Saint Louis Airport near Mascoutah.  His earnings jumped nearly 5 percent last year to roughly $128,000.  The newspaper says Cantwell got his bonus in January for meeting unspecified goals.  Saint Clair County owns the airport and Cantwell oversees its 14 employees and manages a $5.5 million budget.  MidAmerica has struggled since opening in 1998, and critics persistently have labeled it a $330 million boondoggle.
