Which mission suits which aircraft
The Learjet 45XR is the stronger fit for transcontinental missions — its 2,000 nm of range removes fuel stops on those legs. The Citation Mustang, at 1,150 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 Citation Mustang's range, the Learjet 45XR's extra capability is range you pay to carry but rarely use.
Which should you choose?
On published specifications the Learjet 45XR leads on both range and cabin capacity, so it suits operators who want maximum mission flexibility from a single airframe. The Citation Mustang 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.
