N151SY

This airframe, registered N151SY, is an Embraer 175LR (ERJ-170-200LR) built in 2015 with manufacturer serial number 17000503. The airframe is owned and operated by SkyWest Airlines Inc, a corporation based in St George, UT, US; the registration is US. Entered service in 2015 with SkyWest and has been operated in regional airline configuration since delivery. Public records for this specific tail list it as a high-density variant configured for 88 passengers and equipped per typical E-Jets line-fit standards.

The cabin on N151SY is listed in a high-density layout with 88 seats, while the manufacturer documents dual-class 76 as an alternative; the high-density configuration is the active layout for this registration. Typical E-Jet fitment includes the Honeywell Primus Epic avionics suite—here noted as Honeywell Primus Epic (typical E-Jets fitment)—supporting regional airline operations and single-pilot relief procedures at the system level where permitted by operator policy. Operated by SkyWest Airlines Inc from its St. George, Utah location, the aircraft is well suited to short- to medium-haul regional sectors up to its listed range, flying frequent sector rotations and high-cycle utilization typical of regional feeder networks. Maintenance considerations reflect the CF34-8E5 engine shop visit intervals and E-Jets avionics commonality that simplify parts and line support for fleet operators.

The Embraer 175LR occupies the regional jet niche for 70–90 seat operations, balancing fuel efficiency, passenger comfort with 2-2 seating, and airport performance for short runway fields. Competing types include smaller variants of the Airbus A220 family (in some markets) and regional-configured Boeing/Airbus narrowbodies when upgauged; the E175LR's advantage lies in quick turn capability and low single-aisle operating costs for regional networks. Resale and maintenance profiles emphasize CF34 engine lifecycle management and avionics commonality; buyers and lessors generally value high-density-configured units like N151SY for their immediate utility to regional carriers.
