The not-very-useful answer is, tight enough not to leak, not so tight as to damage the threads or fitting. If you need anything more than modest pressure with a short wrench, something is wrong. The better the quality of the flare (and the alignment of the tube to the fitting) and assuming a perfect seat in the fitting, the less additional tightening beyond "snug" is required.
