Which mission suits which aircraft
The Embraer E170 is the stronger fit for transcontinental missions — its 2,100 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 Embraer E170's extra capability is range you pay to carry but rarely use.
Which should you choose?
On published specifications the Embraer E170 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.
