  We model the CR leptonic fluxes above 20 GeV in terms of a superposition of a
standard and a charge symmetric extra component, which we generically describe
as power-laws in momentum. We investigate under these hypotheses the
compatibility between AMS-02, Fermi-LAT and PAMELA datasets on positron
fraction, electron+positron spectrum and electron spectrum respectively. We
find that it is possible to reconcile AMS and Fermi-LAT data within
uncertainties, if energy-dependent effects are present in Fermi-LAT
systematics. We also study possible deviations from charge symmetry in the
extra component and find no compelling evidence for them.
