Delta Air Lines said Thursday it will take delivery of Canadian-made C Series jets this year after Bombardier Inc. scored a big trade victory in the United States against Boeing.

The U.S. airline said it will accept the first of the 75 CS100s it ordered later this year until the Airbus/Bombardier facility in Alabama is up and running.

"The company is evaluating how to best match Bombardier's production capacities with fleet needs," it said in a news release.

Bombardier CEO Alain Bellemare told analysts that it plans to deliver to Delta aircraft assembled in Quebec until a U.S. assembly line estimated to cost $250 million to $300 million is built in Alabama.

"Clearly, the Delta aircraft are in the skyline for 2018, they have always been," he said Thursday during a conference call.

The U.S. International Trade Commission ruled last month that the C Series hasn't caused Boeing material harm even though the Department of Commerce ruled the planes are sold in the U.S. at less than fair value and are subsidized by the Canadian government.

The commission said in a report backing up its unanimous ruling that there is nothing stopping the Montreal-based company from delivering planes assembled in Mirabel, Que., to the American airlines.

The ruling overturned preliminary anti-dumping and countervailing duties totalling 292.21 per cent, although Boeing could appeal.

Delta said Thursday that it is studying the ITC ruling, but added that the exact timing of when the first of the 75 CS100 aircraft it ordered will be added to its fleet "is still to be determined."

Bellemare said the ruling ends a year of turmoil.

"It will increase confidence for customers — existing and potential customers — and is very well received by the industry, the airlines, and consumers will benefit from it," he said.

Bombardier delivered 17 C Series aircraft in 2017, below its forecast of 20 to 22 because of engine delivery delays from Pratt & Whitney.

The company trimmed it net loss in the fourth quarter as the transportation company approached the half-way point in its five-year turnaround drive.

The aerospace and railway manufacturer — which keeps its books in U.S. dollars — lost $109 million, or five cents per share, compared with a loss of $259 million, or 12 cents per share, in the same quarter a year earlier.

Bellemare said the performance allows Bombardier to start the year with momentum.

"We have a clear line of sight to our 2020 objectives and we expect to reach free cash flow break even this year, a key objective of our five-year turnaround plan," he told analysts.

Bellemare said 2018 will be a pivotal year as it moves from large investments in new aircraft to growth with the introduction of its Global 7000 business jet this year and completion of its C Series partnership with Airbus SE.

Bombardier's quarterly revenue totalled $4.72 billion, up from $4.38 billion, but slightly lower than analysts' expectations for revenue of $4.75 billion, according to Thomson Reuters.

On an adjusted basis, Bombardier said it earned $51 million or two cents per share for the quarter compared with an adjusted loss of $141 million or seven cent per share a year earlier.

Analysts on average had expected a break-even quarter for the company.

The company also announced that its stake in Bombardier Transportation will increase by 2.5 percentage points to 72.5 per cent because the division's results outpaced the performance targets in its investment agreement with Quebec pension fund manager Caisse de depot.

For the full year, Bombardier lost $553 million or 25 cents per diluted share, compared with a loss of $981 million or 48 cents per share in 2016.

It swung to an adjusted profit excluding one-time items of $63 million or three cents per share for the year. That compared with a $268-million loss equal to 15 cents per share a year ago.

Year-over-year revenues fell to $16.2 billion from $16.34 billion.

Seth Seifman of J.P. Morgan said he expects investors will react positively after it reported better free cash flow and maintaining its 2018 guidance, including within each division.

On the Toronto Stock Exchange, Bombardier's shares closed up over 11 per cent at $3.66.
