How SFO–BKK 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 BKK 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 a sequence of fare buckets, starting with heavily discounted seats and gradually moving to higher‑priced buckets as demand on the split legs increases.
- Nearby airports: departing from OAK (Oakland Intl), SJC (Mineta San Jose) can change the fare.
