Offices in the terminal? Not sure if that is positive.
Quote from Wikipedia about The fate of Sheffield City Airport
"In the end the last scheduled airline pulled out in 2002, after the airport had passed into the hands of Peel Airports, who were shortly to be opening Robin Hood Airport Doncaster Sheffield airport, approximately 25 miles away.
By the time the last scheduled service was flown, the terminal interior had been converted to office accommodation. Fire and rescue cover and air traffic control staffing levels were both reduced and published procedures for instrument approaches were withdrawn, rendering the airport unattractive to the current generation of airlines which offer low-cost services with turboprop aircraft.
