Abstract: We generalize the respective ``double recurrence- results of Bourgain and ofthe second author, which established for pairs of $L^{\infty}$ functions on afinite measure space the a.e. convergence of the discrete bilinear ergodicaverages and of the discrete bilinear Hilbert averages defined by invertiblemeasure-preserving point transformations. Our generalizations are set in thecontext of arbitrary sigma-finite measure spaces and take the form of a.e.convergence of such discrete averages, as well as of their continuous variablecounterparts, when these averages are defined by Lebesgue space isometries andact on $L^{p {1}}\times L^{p {2}}$ $ 1
