ExpressJet Airlines has announced a series of changes to contracts with major carriers, including termination of an agreement with Delta Air Lines and expanded deals with United Airlines and American Airlines. The company describes the changes in a media release as a "contract realignment" that will provide ExpressJet with a "clearly-defined long-term strategy". ExpressJet, a division of St George, Utah-based SkyWest, will terminate early an agreement under which it operates 61 two-class aircraft for Delta. Those aircraft include 33 Bombardier CRJ700s and 28 CRJ900s, according to SkyWest. The agreement had been scheduled to expire at the beginning of 2019. Under the revised deal, in Q4 2017 ExpressJet will begin returning all 28 CRJ900s to Delta, which owns the aircraft, ExpressJet says. "ExpressJet expects to transition other aircraft previously operated under its Delta agreement to other major partners throughout 2018," adds ExpressJet.<br/>
