How to find cheap flights from Madrid to Reykjavik

Airports: Madrid and Reykjavik

Madrid Barajas Airport (MAD) is 12 km northeast of the city. Metro line 8 reaches Terminal 4 in about 20 minutes; the Cercanías C-1 train connects Terminal 4 with Atocha and Chamartín. Icelandair departs from Terminal 1 — allow extra time to get there.

Keflavík International Airport (KEF) is 47 km from Reykjavik — do not be fooled into thinking you land in the city. The Flybus and competing airport coaches reach the BSÍ terminal in central Reykjavik in about 45 minutes (roughly €25–35 return if booked online). Taxis cost well over €150. If you plan to drive the Golden Circle or the south coast, picking up a rental car at Keflavík on arrival is usually smarter than transferring into the city first.

Money-saving tips

Fly in the aurora shoulder. October and March give you northern lights at lower fares than deep winter or summer.
Bring your own food strategy. Iceland is expensive on the ground — shop at Bónus or Krónan supermarkets and self-cater part of the time.
Skip the Blue Lagoon, or go off-peak. Sky Lagoon and Secret Lagoon cost less; if the Blue Lagoon is the dream, book online well ahead.
Rent a car at the airport. Iceland is a driving destination; airport pickup avoids a redundant transfer into Reykjavik.
Pack layers, not bags. A cabin bag plus a duffel saves baggage fees that add up fast on long Iceland trips.
