AB - We identify the class of Caldern-Lozanovskii spaces that do not contain an asymptotically isometric copy of $\ell _1$, and consequently we obtain the corresponding characterizations in the classes of Orlicz-Lorentz and Orlicz spaces equipped with the Luxemburg norm. We also give a complete description of order continuous Orlicz-Lorentz spaces which contain (order) isometric copies of $\ell _1^{(n)}$ for each integer $n \ge 2$. As an application we provide necessary and sufficient conditions for order continuous Orlicz-Lorentz spaces to contain an (order) isometric copy of $\ell _1$. In particular we give criteria in Orlicz and Lorentz spaces for (order) isometric containment of $\ell _1^{(n)}$ and $\ell _1$. The results are applied to obtain the description of universal Orlicz-Lorentz spaces for all two-dimensional normed spaces.
