How SFO–DUB 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 DUB as separate tickets can undercut the nonstop, with the risk that separate tickets are not protected if you miss the connection.
- Timing: For this route the carrier releases inventory in sequential booking buckets, starting with heavily discounted seats on the feeder leg, then gradually tightening availability on the transatlantic segment as the departure date approaches.
- Nearby airports: departing from OAK (Oakland Intl), SJC (Mineta San Jose) can change the fare.
