just saw this on the news. here is the press release from their site
Clearwater, Florida - July 17 - JetAmerica, the Florida-based public charter operator, announced today that it was suspending sales to all markets and that it would immediately begin to notify affected customers and process refunds to all customers who have booked on the public charter flights.
"We are reluctantly suspending our public charter operations effective today," said John Weikle, CEO, who has been with the company since April. "Finalizing the slots required to support our charter program at Newark has taken longer than expected and we have decided to suspend our operations in order to refocus on different markets. We still strongly believe that there is an unmet need for affordable air service to secondary markets and we look forward to offering this option again in the near future," concluded Weikle.
All customers will receive automatic refunds within 7-14 business days. Any customer not receiving a full refund in 14 days should call 727-451-3970.
