We study the role of anisotropic escape in generating the elliptic flow of bottomonia produced in ultrarelativistic heavy-ion collisions. We implement temperature-dependent decay widths for the various bottomonium states to calculate their survival probability when traversing through the anisotropic hot medium formed in noncentral collisions. We employ the recently developed 3 + 1-dimensional quasiparticle anisotropic hydrodynamic simulation to model the space-time evolution of the quark-gluon plasma. We provide a quantitative prediction for the transverse momentum dependence of bottomonium elliptic flow and the nuclear modification factor for Pb + Pb collisions in $$\sqrt{s_{\mathrm{NN}}}$$ = 2.76 TeV at the CERN Large Hadron Collider.
