How SFO–FRA 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 FRA as separate tickets can undercut the nonstop, with the risk that separate tickets are not protected if you miss the connection.
- Timing: Revenue management releases inventory in sequential booking buckets, initially offering deep‑discounted seats on the feeder leg, then gradually tightening availability on the long‑haul segment as the departure date approaches.
- Nearby airports: departing from OAK (Oakland Intl), SJC (Mineta San Jose), or arriving at MUC (Munich), can change the fare.
