However, some expansion is planned. In order to compete with Icelandair, which operates service from Reykjavik Airport to Nuuk, Narsarsuaq, Ilulissat and the east coast of Greenland and now controls about 15% the market in Greenland-bound travel, Air Greenland may open a nonstop route between Nuuk and Keflavík International Airport in Iceland. Also, owing to improved technology and higher commodity prices, the Maarmorilik mines were due to reopen in November 2010 with zinc and iron ore reserves projected to last 50 years. As in the 1970s, the mine's supply flights to the mine will be operated by Air Greenland, using Bell helicopters (212s) based out of the Uummannaq Heliport.
