Carlisle airport is due to open its new runway today.
The development means that a wider range of general aviation planes, including some private jets such as the Gulfstream 650, Learjet and Citation X 6 Mustange, can now use the airport.
The Civil Aviation Authority gave special approval to operate the 1,799m 30m wide runway within the stated operational procedures.
The news follows the announcement of a series of general aviation offers at the airport, which include discounted landing fees.
Kate Willard, head of corporate projects at Stobart Group, said: “We are delighted that even more general aviation aircraft, including some private jets, can now use Carlisle Lake District Airport.
“The team at Stobart Rail and Civils have made good progress in redeveloping the airport, and the new runway is twice the length of our existing strip.
“I am also pleased to report that our air traffic controller recruitment programme is moving ahead, and the training scheme is on-track for the launch of commercial passenger flights at the airport in spring 2019 with our partner Loganair.”
