The Iraqi Kurdistan region’s first airline launched on Monday a flight to Sweden, after years of delays caused by the ISIS offensive in the country. Officials hope Fly Erbils take-off is a sign of changing fortunes in the autonomous region, which has suffered from the extremist onslaught and a failed independence bid. "ISIS delayed our project but today, we mark real progress," said the airlines chief executive, Laund Sheikh Mamundi, explaining the three-year delay since Fly Erbil first announced its launch. The airline currently has three planes and hopes to increase its fleet to 10, administrative director Ahmad Jamal told AFP. The company advertises flights to five European countries including Germany and the UK, targeting destinations with large Iraqi communities and investors who operate in Iraq, Jamal said. Dressed in a navy blue uniform with golden buttons to match the airlines logo, flight attendant Nisrine Rachid was thrilled the crew would be working in the Kurdish language. "I think that makes them happy and we are delighted to serve them in Kurdish," she said, ahead of the Boeing jet departing from Erbil airport. Iraqi Kurdistan benefited from an economic boom after the 2003 US invasion of Iraq, while the rest of the country descended into violence. But the lightning offensive of ISIS in 2014 led to a significant fall in investments. Last year, a controversial referendum on Kurdish independence led to a series of retaliatory measures by Baghdad which ruled the vote illegal. Disputed areas and their oil fields were retaken by the central government -- a massive hit for the region -- while a nearly six-month air blockade was imposed on Erbil and Sulaimaniyah airports. Kurdistan has relied on its oil wealth to pay back its debts, having borrowed more than $3 billion over three years and paying up with monthly installments of oil barrels.
