Warsaw Chopin Airport for the first time in history – its 10 millionth passenger in a single year. The secondary international airport of the city is the much smaller Warsaw Modlin Airport, which opened in 2012 and is used for low-cost traffic. In 1924, when urban development around Warsaw's aerodrome at Mokotów Field (Pole Mokotowskie) began affecting air traffic, the Ministry of Railways purchased land near the village of Okęcie to construct a new airport.

London City Airport Authority. London City Airport has a single long runway, and a CAA Public Use Aerodrome Licence (Number P728) that allows flights for the public transport of passengers or for flight training (but only for training necessary for the operation of aircraft at the airport). Only multi-engine, fixed-wing aircraft with special aircraft and aircrew certification to fly 5.5° approaches are allowed to conduct operations at London City Airport. The largest aircraft which can be used at the airport is the Airbus A220-100. London City served over 4.5 million passengers in 2017. It is the fifth-busiest airport in passengers and aircraft movements
