Flights from Dulles Intl to Reykjavik: the best tips from KAYAK users' own experiences

Insights shared by verified travelers who flew the route from Dulles Intl to Reykjavik 
Lei-SeaFlew with IcelandairAug 2024
KEF is not like American airport, not a lot of seating and gate is announced when boarding starts so be prepared to move quickly. Food is good in airport and lots of seating around the food areas.
MilyFlew with PLAYMar 2024
Come at least two hours earlier than your boarding time. These “discount” Icelandic airlines are barebones with instructions. Eat outside the airport beforehand. The food sold on Play is very overpriced.
