Cardiff International Airport is mulling over plans to build a new airport terminal.
The airport, which was bought by the Welsh Government in March 2013, is currently outlining its masterplan for growth over the next 10 to 20 years.
It confirmed a new terminal site development may be featured in the plans.
Speaking to the BBC, Cardiff International Airport chairman Roger Lewis said the airport was “significantly improving” the existing terminal and starting its “vision for the future” to build and extend the airport.
This follows the airport’s 16 per cent passenger growth in 2016 with over 1.3m passengers using flight facilities last year.
The airport is 21 km from the M4, for which the Welsh Government has outlined extensive road improvements.
Welsh first minister Carwyn Jones has pledged to deliver major projects across the region including an M4 relief road in south-east Wales.
Plans to improve the A55 in north Wales, A40 in west Wales and other trunk roads have also been outlined.
