How DFW–ICN 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 DFW to a competitive hub and that hub to ICN as separate tickets can undercut the nonstop, with the risk that separate tickets are not protected if you miss the connection.
- Timing: Airlines release inventory in sequential fare buckets, starting with heavily discounted seats and progressively moving to higher‑priced buckets as demand on the DFW‑ICN sector increases.
- Nearby airports: departing from DAL (Dallas Love Field), or arriving at GMP (Seoul Gimpo), can change the fare.
