Around 25,000 new passenger planes will be needed over the next 20 years, aircraft company Airbus has forecast.
These planes will have a value of around 1,880bn, with 10,000 of the new planes replacing older and "less-green" aircraft.
The other 15,000 will be to accommodate passenger growth, said Airbus whose planes' wings are built in the UK.
Demand for ultra-large aircraft such as the Airbus A380 superjumbo is expected to account for seven per cent of the total number of new planes over the next 20 years.
Around 24 per cent of the new aircraft will be twin-aisle planes, with 69 per cent being single-aisle aircraft.
The world's passenger fleet amounts to more than 14,000 planes at the moment and this is expected to rise to 29,000 by 2029.
