JetAmerica, a fledgling discount airline that garnered attention with $9 promotional fares, has folded without ever getting off the ground.

JetAmerica’s was supposed to be the latest chapter in startup airlines organized by John Weikle, 59, a Tipp City entrepreneur who founded the ill-fated Skybus low-fare airline in 2007. Skybus failed within a year, piling up costs and struggling with high fuel prices.

Weikle also tried to start up HeartLand Airlines years ago to serve Dayton business travelers, but left in 2000 in a disagreement about who should run that company. HeartLand never started operations and dissolved in 2001.

The Clearwater, Fla.-based company says it’s suspending sales to all markets and will immediately begin to process refunds to customers. Service was originally supposed to begin July 13 to underserved markets in Toledo, Ohio; South Bend, Ind.; Melbourne, Fla.; and Lansing, Mich. Flights were also scheduled to larger airports in Minneapolis and Newark, N.J.

JetAmerica announced July 2 that it was delaying the launch of flight operations by a month and refunding its first $500,000 in sales because of problems securing landing slots at Newark Liberty International Airport.

The company cited those problems in its announcement Friday.
