How SFO–HND gets cheaper
- Regional point-of-sale pricing: the same flight is often filed at different tariffs in different countries and currencies. How it works.
- Split-hub routing: pricing SFO to a competitive hub and that hub to HND as separate tickets can undercut the nonstop, with the risk that separate tickets are not protected if you miss the connection.
- Timing: Revenue‑management for SFO‑HND cycles through high‑fare inventory early, then opens discounted buckets as booking pace slows, with the split‑hub legs each following their own domestic and international inventory curves.
- Nearby airports: departing from OAK (Oakland Intl), SJC (Mineta San Jose), or arriving at NRT (Tokyo Narita), can change the fare.
