United Airlines said that it expects to return the Boeing 787 Dreamliner to service in May.
United is the only U.S. airline that flies the 787, which was grounded worldwide in mid-January because of a faulty battery design.
“We are eager to get this remarkable aircraft back up,” said United CEO Jeff Smisek during a call discussing the airline's first-quarter results.
He said that the grounding of the 787 disrupted flight plans and “had an impact” on the bottom line.
United Airlines posted a first-quarter net loss of $417 million, a bit narrower than the $448 million loss in last year's first quarter.
Operating expenses increased 1.3% and consolidated unit costs excluding special items jumped 7.4%.
