The first Embraer 175 bound for United Airlines rolled out of the factory in Sao Jose dos Campos, Brazil, on 12 March.
The aircraft is also the first E175 enhanced variant, which boasts 6.4% lower fuel burn than the base E175 and includes a new winglet and aerodynamic clamps.
Utah-based regional carrier SkyWest Airlines plans to take delivery of the aircraft during the week of 24 March with entry-into-service scheduled for a flight between Chicago O’Hare and Washington National on 17 May. Future service includes flights from Chicago to Atlanta, Boston, Minneapolis-St. Paul and New York LaGuardia.
The E175 is configured with 76 seats, including 12 in first class, 16 in economy plus and 48 in economy.
United plans to have 70 E175 enhanced aircraft in its regional fleet by the end of 2015. These are split between 40 owned and operated by SkyWest, and 30 operated by Mesa Airlines and owned by the mainline carrier.
The aircraft will be used to replace up to 50-seat regional jets and allow United to better compete with American Airlines and Delta Air Lines who both began replacing small jets with larger Bombardier CRJ900s and E175s in 2013.
