We report on magnetoconductance measurements of an open two-dimensional ballistic cavity in a tilted magnetic field. In agreement with Folk et al. (Phys. Rev. Lett. 86 (2001) 2102), we show that, due to an increasing spin-orbit interaction, the variance of conductance fluctuations decreases when a large in-plane magnetic field is applied. When the magnetic field is applied parallel to the 2DEG, we observe a negative magnetoconductance peak around zero total field, which is reminiscent of the weak antilocalization effect induced by spin-orbit interaction.
