Boeing Co (BA.N) said it expects airline passenger traffic to rise more than 6 percent in 2015, possibly close to 6.5 percent, above its long-range forecast of about 5 percent. “We’ve got work to do,” to hit the order target, Randy Tinseth, Boeing vice president of marketing, said in a series of briefings ahead of the Paris Airshow that starts June 15. Boeing’s forecast is in line with actual growth in air travel.
