United is pulling out of the Elmira Corning Regional Airport in western New York. The carrier’s last flight there will be April 4. "I was obviously very disappointed. The airport is a major asset to the region," Chemung County Executive Tom Santulli said. "We're always trying to advance service opportunities. (United) did a trial run to see what the service would be. Their load factor was only in the 40% range.” The Elmira Corning airport is about 20 miles north of New York’s border with Pennsylvania, sitting near a part of the Keystone State that has prospered financially in recent years from natural gas production around the Marcellus Shale formation. But that momentum has slowed during the past year amid a global decline in fuel prices.<br/>
