Embraer captured an order from United Airlines for up to 39 70-seat E175s valued at $1.9 billion, should all options be exercised, the Brazilian manufacturer announced on Monday at the Paris Air Show. United placed a firm order for 20 of the airliners, with deliveries to begin in the second quarter of 2020, and has options on 19 more.

United Airlines will use the new E175 to replace older 70-seaters currently in service with its regional partners. “The E175, operated by our regional partners, has proven to be an important part of our fleet as we continue to grow our mainline airline and provide an enhanced customer experience,” said United CFO Gerry Laderman.

The order boosts the cumulative number of E175s that Embraer (Chalet 286) has sold to North American customers over the past six years to 585. This has given Embraer an 80 percent market share of the 70- to 76-seat segment in the region, the Brazilian airframer added. Firm backlog for the model stood at 196 at the end of March.
