My company forbids visual approaches at night unless there is an instrument approach that can back up the visual. Is it possible that is LH policy and there was confusion on the pilots part? It also sounds like the controller was going to work it out by granting the ILS but having LH report the parallel traffic in sight. Does LH policy forbid that? The last question is what is the max duty day for LH pilots on that flight. Looks like they were pushing 17 hours to get back to SFO.
