(GLOBALPOST) — Shares in United Airlines soared more than two percent today after the company flew into aviation history by becoming the first US airline to fly paying passengers on Boeing’s new fuel-efficient 787 Dreamliner.

After a three-year delay due to production problems at Boeing, United Airlines landed its first domestic flight of the state-of-the-art Dreamliner at Chicago’s O’Hare International Airport on Sunday, the Los Angeles Times reported.

Investors appeared to be as relieved as United Airlines chief executive Jeff Smisek, who was on the inaugural two-and-a-half-hour flight from Houston.

“It’s been a long haul to get here,” Smisek was quoted by the Chicago Tribune as saying.
