Sinclair is currently the CEO of Bristol Airport but has decided to leave the position he has held since 2008 for the challenge of running London City Airport (LCY).
Bristol Airport has witnessed record traffic growth and profitability during his time at the airport, in which he has successfully overseen a £160 million development programme.
Prior to taking on the role at Bristol, New Zealand born Sinclair was the chief financial officer of Auckland International Airport and also enjoyed a 10 year career with UBS in investment banking.
He is expected to take up the role at London City Airport from Monday, October 30, 2017.
On his new role, Robert Sinclair remarks: “I’m excited to be joining London City Airport.
"It’s an airport that plays a vital role in connecting Britain, and in particular its business community, globally and through the City Airport Development Programme it will be able to serve 6.5 million passengers per year, and 111,000 flight movements by 2025 – adding much needed aviation capacity at a time when Britain needs it most.”
London City Airport chairman, Sir Terry Morgan says: “On behalf of the Board I want to welcome Robert to London City Airport.
"He arrives at a very exciting point in the growth of the airport with our City Airport Development Programme due to commence from the end of this year.
"I have no doubt that the experience that he brings from his time at Bristol Airport and Auckland Airport before that will be very important in this next stage of London City Airport’s success story.”
Current incumbent and Airports Council International (ACI) World chairman, Declan Collier, announced his intention to step down from the role earlier this year.
