    •Unlike the traditional routine, the Cattaneo–Christov heat flux in formulation is employed.•Variable thermal conductivity is accounted.•Surface with variable thickness is considered.•Double stratification is analyzed.•Nonlinear stretching phenomenon is imposed. Here temperature dependent thermal conductivity in stagnation point flow toward a nonlinear stretched surface with variable thickness is considered. Heat flux in formulation is based upon Cattaneo–Christov theory. Double stratification and chemical reaction effects are further retained. Convergent series solution for flow of Jeffrey fluid and heat and mass transfer are developed. Residual errors are calculated for the velocity, temperature and concentration equations and results are discussed through graphs. Influences of skin friction coefficient is also studied. It is observed that temperature profile decreases for higher thermal relaxation parameter.
