SkyWest Airlines (OO, St. George Municipal) has announced it will add twenty incremental E175s under a four-year contract with United Airlines (UA, Chicago O'Hare), with deliveries expected throughout 2024.

The new agreement is incremental to a previously announced deal for nineteen E175s, which SkyWest ordered last year from Embraer to operate for United. The deliveries of those aircraft are expected to begin this year, with the first four, followed by seven in 2025 and eight in 2026, according to the investor update from SkyWest.

"The 20 aircraft are United-owned and are expected to enter SkyWest operations throughout 2024. We are working with United to finalize timing of the deliveries," SkyWest told ch-aviation.

United did not respond to ch-aviation's question about the source of the aircraft. Currently, the other regional operators of the E175 flying under the United Express banner are Mesa Airlines (YV, Phoenix Sky Harbor), which operates 79, including 61 owned by United, and Republic Airways, which operates 45, including 29 owned by United.

The ch-aviation fleets module shows that SkyWest already operates E175s on behalf of all major mainline carriers in the United States, including 42 on behalf of Alaska Airlines, 20 on behalf of American Airlines, 85 on behalf of Delta Air Lines, and 90 for United. It also operates 132 CRJ200s, fifty-five CRJ700 Srs 701s, forty CRJ700 Srs 701ERs, twenty-one CRJ700 Srs 702s, sixteen CRJ700 Srs 702ERs, and forty-four CRJ900s. Its Part 135 subsidiary, SkyWest Charter, operates a further sixteen CRJ200s.
