AFAICT #3 (JL1 SFO-HND) is aimed at business travelers like me going HND-SFO-HND.
Exit Haneda around 5am and enjoy the last N minutes to the office in a cab.
Agreed. The late departure time from both airports is quite businessman-friendly as well. However, the arrival time in SFO is in the middle of rush hour, which a late-morning arrival would miss. Just something to think about for your return leg.
