This is the main airport in Iceland and is likely where you'll begin and end your trip. There are several Duty Free shops and dining options in both the arrival and departure terminals. Know that Keflavík International Airport (KEF) is about a 40 minute drive from Reykjavik city centre and it is NOT the same as Reykjavik Domestic Airport (RKV).

Tip: The duty free shops are the least expensive place to buy alcohol in Iceland.
