Bristol International Airport has released the first computer-generated images of its proposed expansion.
The south-west airport wants to extend the size of its single terminal to handle ten million passengers a year by 2016.
Commenting on the plans, Alan Davies, director of environment and planning at Bristol International Airport, said he wanted Bristol to enhance its reputation as a regional gateway for international travel.
"Demand for air travel to and from the south-west is forecast to grow, and by increasing the choice of services we offer and enhancing the facilities we provide to passengers we can reduce reliance on airports outside the region," he said.
Under the new scheme, new walkways will be built between the enlarged terminal and apron extensions which will reduce the need for buses to carry passengers to their aircraft.
A full planning application will be submitted to north Somerset Council following a public consultation with local community representatives.
Bristol was the ninth busiest airport in the UK in 2007, handling just under six million passengers.
