Airport Information & Terminals
KEF: Reykjavik airport. Airport access in Reykjavik depends on arrival time, terminal, hotel location and local traffic. Confirm the airport name on the ticket, then choose between official taxi, app cab, airport bus, rail or hotel transfer based on luggage and time of day.
DEN: Denver airport. Denver airport transfer should be matched to the exact hotel, suburb or meeting area. Rail can work well for light luggage, but late arrivals, winter weather and family baggage often make a direct cab or booked transfer easier.
