Well, since 18 is invisible unless things get dicey and they haven't added a new 'Visual" Code to the Field 10 Approach Capabilities (or is that invisible too?) to accommodate those who can't be assumed to have eyeballs, it looks like LH has created an impossibly complicated, 4-dimensional chess problem of how Ops or crew can communicate to ATC their Company's nighttime restriction before showing up on SFO's doorstep late after dark with Visuals already in progress.
It's a shame it's so terribly difficult because, after all, LH crews and Ops know through long and frequent experience these Visuals are likely when it's VMC at SFO, flying them regularly during daylight. Sigh, If only there was a way, life might be easier for everyone.
