Direct flights between Anglesey and Cardiff will continue
The First Minister says direct flights between Cardiff and Anglesey will continue in the "long term".
The service from Cardiff to Anglesey Airport has struggled with low passenger numbers and various operators pulling out of the route.
But the Welsh Government says the service will continue as "it is the quickest way of travelling between North and South Wales for business travellers and tourists".
First Minister Carwyn Jones said: "Following a thorough review in 2016, I'm pleased to announce the Intra Wales Air Service between Cardiff and Anglesey will continue.
"The review found that, while the service has faced difficulties in the past - not least in terms of former operators - it provides a quick and convenient way to travel between north and south Wales, which is vital for our economy.
"The review recommended not only retaining the air link, but also helping it to grow. We are now looking at how the scope of the route can be expanded over the next four years and beyond, to help boost the Welsh economy.
"The competitive procurement of a long-term operator will begin in the next few months. In the meantime, the current operator, Eastern Airways, will continue to deliver the service, ensuring there is no disruption for passengers."
