About the canadair CRJ-900

The Bombardier CRJ900 is the stretched flagship of the CRJ family, seating 76 to 90 passengers in a twin-engine regional jet configuration that redefined scope-clause economics for North American carriers. Launched in 2001 as an answer to Embraer's E-Jet challenge, the CRJ900 extends the fuselage of the smaller CRJ700 by nearly 14 feet while retaining the same wing and General Electric CF34-8C5 engines, creating a high-density regional workhorse that operates profitably on 300- to 1,500-mile routes. Its 1,553-nautical-mile range and 41,000-foot service ceiling allow it to overfly weather and serve thin markets that can't fill mainline narrowbodies, making it the backbone of Delta Connection, SkyWest, and Endeavor Air fleets.

The type's long, slender fuselage and distinctive T-tail give it excellent high-speed cruise performance—Mach 0.85 maximum operating speed matches many narrowbodies—though the single-aisle 2-2 seating and stand-up cabin height of just 6 feet 1 inch remind passengers this is purpose-built regional iron, not a scaled-down mainline jet. Despite competition from the Embraer E175 and later E190-E2, the CRJ900 remains in production and continues to dominate the 76-seat scope-limited segment in the United States, where pilot contracts cap regional jet size. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
