[1] Bellanca Aircraft, 1927–present, was based out of New Castle, Delaware during its most influential period from 1928 to 1954.

Many aerospace companies are incorporated in Delaware because of favorable tax status.

In June 2013, Frontier Airlines began service from the airport to numerous destinations throughout the country.
