About the Embraer ERJ 145 XR

The Embraer ERJ-145 family revolutionized regional aviation in the late 1990s as the world's first purpose-built 50-seat regional jet, breaking the turboprop monopoly on thin routes and enabling major carriers to offer pure-jet service to smaller markets. The E45X designator specifically covers the ERJ-145XR (Extra Range) variant, which extended the baseline ERJ-145's range from 1,550 to 2,200 nautical miles through increased fuel capacity, making transcontinental regional routes economically viable for the first time. Powered by twin Rolls-Royce AE 3007 turbofans mounted on the aft fuselage, the aircraft cruises at 37,000 feet and Mach 0.78, matching mainline jet performance while operating from runways as short as 5,000 feet.

The type entered service in 1997 and became the backbone of U.S. regional carriers operating as United Express, American Eagle, and Delta Connection, with over 1,000 ERJ-145 family aircraft delivered worldwide. Its 50-seat cabin configuration—driven by U.S. scope clause restrictions limiting regional partners to that capacity—made it the workhorse of hub-and-spoke feed operations throughout the 2000s. The aircraft's relatively high approach speed of 125 knots and maximum operating speed of 320 knots IAS (Mmo 0.78) positioned it closer to mainline narrowbody performance than competing turboprops, though its single-aisle 1-2 seating and limited overhead bin space drew passenger complaints on longer sectors.

While production ended in 2020 as the industry shifted toward larger 70-76 seat jets and the E-Jet family, hundreds of ERJ-145s remain in daily service on short-haul routes across North America, particularly in the United Express fleet. SkyMeter has tracked flights across airframes and operators spanning routes, with the largest observed operator.
