An Eastern Air Lines plane sits outside the terminal at Lexington’s Blue Grass Field in 1966. Just three years earlier, the longest non-stop flight out of the airport was to Boone County. By 1966, 20 years after Blue Grass Field began commercial service, the airport offered 26 flights a day including non-stop service to Chicago, New York City and Washington D.C. Three airlines operated out of the airport at this time; Delta, Eastern and Piedmont. Click here to see a picture from our archives of the inside of the terminal building. Two years later, 1968, was a milestone year for the airport with a terminal remodel, the addition of Allegheny Airlines, a runway extension and the first commercial jet flight out of Lexington.
