Denver International Airport’s longest-ever flight — a nonstop leg from Denver to Istanbul — will take to the skies for the first time Tuesday evening. The new Turkish Airlines flight will carry Colorado travelers 6,130 miles to Istanbul, marking the longest flight in DIA history, airport officials announced in April. The flight will take about 13 hours, longer than the 12-hour, 5,788 mile direct flight between Denver and Tokyo. “This new partnership is expected to produce over $54 million in annual economic impact for Colorado and approximately 350 new jobs,” airport officials said. The first flight is scheduled to take off from Denver at 6:05 p.m.
