The measurements of the cosmic ray $\mbox{e}^{\pm}$ and ($\mbox{e}^{+}+\mbox{e}^{-}$) fluxes based on the analysis of the first 30 months of data collected by the AMS-02 detector onboard the International Space Station is reviewed. The collected statistics and the resolution of the detector provide unprecedented accuracy in the analysis of the energy dependence of the $\mbox{e}^{\pm}$ and the ($\mbox{e}^{+}+\mbox{e}^{-}$) fluxes and of the positron fraction. The results provide new interesting information on the properties of $\mbox{e}^{\pm}$ cosmic rays.
