How DEN–KEF 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 DEN to a competitive hub and that hub to KEF 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‑bucket waves, with the feeder leg filling first at a discounted level before the long‑haul segment’s higher‑priced buckets are opened.
- Nearby airports: check alternate departure airports can change the fare.
