The low-cost carrier ceased operations over the weekend, stranding thousands of passengers who had already purchased tickets.
Spirit had maintained a major presence at Atlantic City International Airport, accounting for roughly 75% of its commercial air service, according to airport officials.
Airport Director Tim Kroll said relief is on the way, with low-cost carrier Breeze Airways set to begin operations at the airport on Wednesday.
"They did announce late Saturday evening that they are going to help fill some of these Spirit markets," said Kroll. "They are starting Orlando in July. It'll go to daily service in October, plus Ft. Myers, and Myrtle Beach in October, as well as West Palm."
Kroll said the airport expects the lost service to be fully replaced by December.
"The gap will be filled eventually. We know we will have some short-term pain, but in the long term, we'll have plenty of opportunity to grow even further," said Kroll.
Spirit Airlines said it will begin issuing refunds for passengers whose flights were canceled. The U.S. Department of Transportation said credit card refunds should be processed within seven days, while refunds issued through other forms of payment could take up to 20 days.
However, Spirit noted that customers who paid with Spirit Points may have those balances addressed through the airline's bankruptcy process.
