Emirates is an airline based in Dubai, United Arab Emirates. The airline is a subsidiary of The Emirates Group, which is wholly owned by the government of Dubai's Investment Corporation of Dubai. It is the largest airline in the Middle East, operating over 3,600 flights per week from its hub at Dubai International Airport, to more than 150 cities in 80 countries across six continents. Cargo activities are undertaken by Emirates SkyCargo. Emirates is the world's fourth largest airline in scheduled revenue passenger-kilometers flown, the fourth-largest in terms of international passengers carried, and the second-largest in terms of freight tonne kilometers flown. From March 2016 to February 2017 Emirates had the longest non-stop commercial flight from Dubai to Auckland. Emirates operates a mixed fleet of Airbus and Boeing wide-body aircraft and is one of the few airlines to operate an all-wide-body aircraft fleet (while excluding Emirates Executive). As of February 2019, Emirates is the largest Airbus A380 operator with 109 aircraft in service and a further 14 on order. Since its introduction, the Airbus A380 has become an integral part of the Emirates fleet, especially on long-haul high-traffic routes. Emirates is also the world's largest Boeing 777 operator with 151 aircraft in service. As of August 2018, Emirates operates a fleet of more than 250 aircraft. Emirates operates the largest fleets of Airbus A380s and Boeing 777s in the world, with one A319 as an executive jet. Emirates has had no narrow-body aircraft in its mainline fleet since 1995. In July 2014, Emirates finalized an order for 150 Boeing 777X aircraft, consisting of 35 777-8s and 115 777-9s, and, as of October 2017, was expected to become the launch operator for the 777X in mid-2020. In November 2017, it signed a commitment for 40 787-10s, but by early 2019 it was considering cancelling this order due to engine margins being insufficient for the hot Dubai weather, in favour of the A350. In February 2019, Emirates signed a deal with Airbus for 40 A330-900s and 30 A350-900s, while reducing its A380 order; 14 A380s remained to be delivered, after which Airbus will cease production of the A380.
