Avelo is adding nine routes from Wilmington Airport in Delaware for what it said is the "largest number of nonstop routes ever offered" at the hub.
The additions take the airline to 14 destinations out of Wilmington, with the expansion to be served by a second Boeing 737 and "at least 35" extra staff for more than 100 crew based at the airport.
"The strong demand we are generating out of the gate is a testament to the convenient, affordable, reliable and caring air service Avelo has introduced to the Delaware Valley, " said Andrew Levy, Avelo's chairman.
The routes being added include Charleston, Daytona Beach and Nashville.
"Based on this initial customer response to our first five Florida routes, we are excited to bring Wilmington these nine new routes to several of our most popular east coast destinations," added Levy, who is also chief executive.
“We are grateful that Avelo will be expanding service here in Delaware, and we are excited to welcome more visitors to the First State," said John Carney, Delaware's governor.
