Republic Airways will provide an $8 million line of credit to Mokulele Airlines and place four of its Embraer 170s with the Hawaiian carrier in November. The intra-island Mokulele will operate the 70-seat regional jets using crew from the Indiana-based regional. It will also hire some workers who were laid off when Aloha Airlines shut in April. Mokulele now flies Cessna Caravans. The Embraers, assigned to Republic subsidiary Shuttle America, had been flown for Frontier Airlines.
