Services are returning to normal at London City Airport after fog over east London led to flights being grounded.
Planes had not been able to land at the Docklands airport all morning due to low visibility and five incoming flights were diverted to Heathrow and Gatwick airports.
Fourteen incoming flights and 18 take-offs were cancelled and other flights were delayed until later.
The airport said there remained minor delays due to the earlier backlog.
Services on the Woolwich ferry in south-east London, which links Woolwich to North Woolwich, were also suspended this morning because of the fog.
A London City Airport spokeswoman advised passengers to contact their airlines for further information.
