Myrtle Beach International Airport spokesperson Lauren Morris says Direct Air owes the airport $174,912.59.
She says the airport had been working with new management and investors of Direct Air to collect the past due amounts and develop marketing and service strategies for the upcoming season.
Morris says Direct Air had been making payments. The last one was received March 5, 2012.
She says the airport maintains an allowance for bad debt to cover events of default and that the allowance is enough to cover the amount due from Direct Air.
The airport has issued a Notice of Default to Direct Air in accordance with the airline use agreement.
The airport has been in contact with DOT/FAA regarding the collection of past due amounts and filing the appropriate claims.
