Finnair has been named northern Europe’s best airline by the Skytrax 2013 World Airline Awards for four consecutive years. The award is given based on a survey of 18 million travelers from more than 160 countries on their overall airline experiences. The passenger survey asks customers to rate their satisfaction with areas including check-in, boarding, seat comfort, cabin cleanliness, food, beverages, in-flight entertainment and staff service. The World Airline Awards, given by Skytrax, a U.K.-based consultancy group, are regarded as the primary benchmark for airline passenger satisfaction.
