ARJ21-700 vs ERJ-145: the key differences

  • The ARJ21-700 delivers 44% more range (ARJ21-700: 2,225 nm; ERJ-145: 1,550 nm).
  • The ERJ-145 delivers 7% more cruise speed (ARJ21-700: 422 kt; ERJ-145: 450 kt).
  • The ARJ21-700 delivers 80% more passenger capacity (ARJ21-700: 90 seats; ERJ-145: 50 seats).
  • The ARJ21-700 is the newer design (introduced 2016 versus 1996 for the ERJ-145), a gap of 20 years that usually shows up in avionics, cabin systems and fuel burn.
  • The ARJ21-700 is the larger aircraft by maximum takeoff weight (89,947 lbs versus 48,501 lbs), which typically buys more cabin and payload at the cost of higher trip economics.

Which mission suits which aircraft

The ARJ21-700 is the stronger fit for transcontinental missions — its 2,225 nm of range removes fuel stops on those legs. The ERJ-145, at 1,550 nm, is better matched to regional and short-to-medium legs, where lower trip cost counts for more than outright reach. If most of your flying sits inside the ERJ-145's range, the ARJ21-700's extra capability is range you pay to carry but rarely use.

Which should you choose?

On published specifications the ARJ21-700 leads on both range and cabin capacity, so it suits operators who want maximum mission flexibility from a single airframe. The ERJ-145 can still be the smarter buy on acquisition cost, operating economics, runway performance, or current availability — the factors that rarely show up in a spec sheet. Our acquisition advisory team can model both against your actual mission profile before you commit.
