Soon it will be impossible to fly any airline to Delaware as the only commercial operator there is pulling its remaining service from the state.

New Castle Airport, which is situated near Wilmington, Delaware, will say goodbye to its only commercial airline on June 6 as Frontier Airlines will leave the airport, ending its service between there and Orlando, Florida, an airline spokesperson told Business Insider.

The spokesperson told the news outlet that “sufficient demand did not materialize to support the service.”

New Castle Airport recently underwent $2 million in renovations to its screening areas and passenger terminal to support Frontier’s 2021 return after it initially departed the state in 2015 after two years, the Delaware News Journal reported.

Delaware River and Bay Authority spokesperson Jim Salmon told the Delaware News Journal that the DRBA, which operates the airport, is “disappointed” in Frontier’s decision but continues to believe commercial air service at the airport “can and will succeed.”

Delaware will now be the only U.S. state without commercial airline service. However, New Castle Airport will continue to operate charter and general aviation flights.

But Frontier hasn’t entirely eliminated Delaware from its flight plans as the airline told Business Insider, “we are continually evaluating our routes and ILG [New Castle Airport] will certainly remain in the consideration set for potential service in the future.”
