N780YX

N780YX is an Embraer 175LR (ERJ-170-200LR), MSN 17000991, registered to Republic Airways Inc and operated on United Express services. The airframe was delivered into U.S. service in May 2025 and entered scheduled United Express operations shortly thereafter. The LR (Long Range) airframe is certificated in a high-density layout but is commonly operated in dual-class regional service. The airframe carries United/United Express titles and the fleet number 780 on the forward gear door.

N780YX is operated by Republic Airways on behalf of United Express in typical 70–76/76-class regional rotations, though FAA-recorded certification lists up to 88 seats. The aircraft is powered by two General Electric CF34-8E turbofan engines (each rated ~14,200 lbf) and is used on short- to medium-haul trunk and regional routes. Typical mission profiles are 1–3 hour flying sectors connecting spoke airports to United hubs; examples include Madison–Chicago and Toronto–Newark legs in summer 2025. The cabin for United-configured E175LRs normally features a small premium/business cabin and economy, with inflight service and single-aisle regional ergonomics; avionics are the standard E-Jets fit, a Honeywell-class integrated suite.

The Embraer E175LR is a stretched member of the E-Jet family offering improved range and capacity over the E170 while retaining the E-Jets' cockpit and systems commonality. The type is widely used by North American regional operators for its balance of fuel efficiency, passenger comfort and commonality with E170/190 operations. Performance highlights include ~2,200 nm maximum range (LR/AR variants), a service ceiling near 41,000 ft and cruise capability in the Mach 0.75–0.82 band, making it suitable for both high-frequency short-haul and longer thin trunk routes. The CF34-8E powerplant and E-Jet airframe combination remain competitive in regional markets and continue to be supported by active airline and MRO fleets.
