Spectrum of excitons in double-quantum-well structures is calculated in tilted magnetic field. It is shown that spectrum becomes asymmetric in quasimomentum if a transverse in respect to growth direction component of magnetic field is nonzero. A transition from $k$-space direct exciton ground state to $k$-space indirect one accompanied by sharp quenching of photoluminescense is described.
