The company, based in Miramar, Florida, announced the expanded service days before it is set to start nonstop service to Fort Lauderdale, Florida, and Houston on Aug. 1. “We are excited that Spirit continues to expand service at Armstrong International,” New Orleans Aviation Director Iftikhar Ahmad said. “The daily flights to Chicago and Detroit will offer our community a convenient, ultra-low-cost option for traveling to these cities.” Spirit currently offers nonstop flights to Dallas/Fort Worth.
