I wouldn't be suprised if these kinds of things are why they are going to smaller airports.

"The Lansing, South Bend, Melbourne and Toledo airports are subsidizing JetAmerica with $1.4 million in grants in its first year, along with about $867,000 in waived airport fees and $1.1 million in marketing and advertising assistance.
South Bend, Toledo and Melbourne received their grants from the U.S. Department of Transportation's Small Community Air Service Development Program, which has awarded $104 million to 223 recipients since 2002 in an effort to restore lost service and bring air fares down."
