The airport, which bills itself as a convenient and speedy transport hub for London's City executives, has tasked the agency with the overhaul of its website, corporate marketing activities and communications.
The appointment comes quickly on the back of approval for its application to allow the airport to accommodate up to 120,000 flights a year, up from 80,000. It currently flies to 33 UK and European destinations.
The airport's strategy plan claims it can accommodate 8 million passengers by 2030 to support the growth of business travel, whilst ‘also remaining good local neighbours and maintaining an excellent environmental record'.
It has tried to combat high-profile criticism from environmental campaigners by insisting it will continue to close at night and for 24 hours at the weekend and will not add an additional runway.
London City Airport claims to have made a ‘significant contribution' to the local economy and the regeneration of East London.
Next month, British Airways will start running its first ever all-business transatlantic service with flat bed seats to New York on the Airbus A318 from London City in a bid to target passengers working in London and New York's financial districts.
Club World London City, the new service will be given the airline's most prestigious flight number, BA001, previously used by Concorde.
Last year, London City Airport saw a 12% rise in passenger numbers, with a record 3.3 million people travelling through the Docklands airport.
As part of a £50m investment, it started an overhaul of its facilities last summer, with construction of four new aircraft parking stands and departure lounges increasing passenger seating by 250. It also introduced kiosks in the terminal concourse.
