This specific E175LR is fitted in a two-class, 76-seat regional layout listed as Two-class 76-seat regional layout (approx. 12 business/premium + 64 main / operator variations exist; typical Alaska configuration shows 76 total), reflecting operator-configurable seating density within the E-Jets family; SkyWest’s configuration emphasizes regional trunk and thin-route flexibility. Avionics are noted as Honeywell / typical E-Jets-class avionics (operator-fit varies), indicating a standard E-Jets flight deck with operator-specific mission equipment. With a 2,200 nm range, 447-knot cruise and 41,000 ft service ceiling, the airframe is optimized for short- to medium-haul regional services, high-frequency turnarounds and multi-leg daily utilization common to regional carriers. Maintenance considerations follow typical E175LR operator practices, with logistics and component support aligned to SkyWest’s fleet management.
The Embraer ERJ-170-200LR (E175LR) occupies the regional jet performance niche delivering a balance of passenger capacity and range for mainline feed and regional point-to-point service. Competing models in this segment include other single-aisle regional jets with comparable seat counts and ranges; demand centers on airlines and regional operators seeking high-frequency, lower-capacity equipment. Maintenance and resale considerations for this 2018-built airframe hinge on engine time on type (CF34-8E) and operator maintenance pedigree; owner continuity with SkyWest Airlines Inc supports predictable records for lifecycle and remarketing.
