  In this letter we investigate acceleration in the flat cosmological model
with a conformally coupled phantom field and we show that acceleration is its
generic feature. We reduce the dynamics of the model to a 3-dimensional
dynamical system and analyze it on a invariant 2-dimensional submanifold. Then
the concordance FRW model with the cosmological constant $\Lambda$ is a global
attractor situated on a 2-dimensional invariant space. We also study the
behaviour near this attractor, which can be approximated by the dynamics of the
linearized part of the system. We demonstrate that trajectories of the
conformally coupled phantom scalar field with a simple quadratic potential
crosses the cosmological constant barrier infinitely many times in the phase
space. The universal behaviour of the scalar field and its potential is also
calculated. We conclude that the phantom scalar field conformally coupled to
gravity gives a natural dynamical mechanism of concentration of the equation of
state coefficient around the magical value $w_{\text{eff}}=-1$. We demonstrate
route to Lambda through the infinite times crossing the $w_{\text{eff}}=-1$
phantom divide.
