On most flights passengers can complete Icelandair check-in online up to 36 hours in advance. The exception to this is any flight that is destined for, or originates from the U.S. For these flights online check-in opens 24 hours in advance of departure. In addition, passengers on flights leaving a North American airport will have to collect a boarding pass from the airport counters, regardless of whether they have checked in online.
Icelandair check-in can also be completed at the airport, either at a counter or a self-service kiosk. The airline has self-service kiosks at the airports of Vancouver, Montreal, Edmonton, Denver, Chicago O'Hare, Boston, Seattle, Stockholm Arlanda, Paris Orly, Paris CDG, Oslo, London Heathrow, Frankfurt, Copenhagen, Billund, Amsterdam Schiphol, Aberdeen and Keflavik.
