Revised plans by Stobart Air for the expansion of Carlisle Airport have won the support of Cumbria County Council's development control committee.
The endorsement will go forward to Carlisle City Council to decide next month if the £20m scheme for an Eddie Stobart headquarters and 371,000 sq ft warehouse should get planning consent.
The county council suggested that Stobart be made to sign a formal agreement to upgrade the airport's runway and passenger terminal.
Stobart Air should also provide a bus service, improve landscaping and adapt the warehousing to allow use by air freight, the county council added.
The revised plans follow the deicison by Government to call in the original plans, for a larger development, for public inquiry.
Stobart threatened to pull out of its Kingstown, Carlisle base, where it employs 565 people and close the airport in 2011 if its plans are turned down.
