How MIA–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 MIA 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 a limited number of seats in the cheapest bucket for the feeder leg, then opens higher‑priced buckets as demand rises, while the long‑haul segment follows its own inventory cadence.
- Nearby airports: departing from FLL (Fort Lauderdale-Hollywood) can change the fare.
