Airline Flybe is due to announce today four new routes to fly from Cardiff Airport this winter.
The low-cost carrier currently operates flights from Cardiff to 16 destinations, in the UK, Ireland, the Channel Islands and continental Europe.
Details of the new routes will be available later.
Flybe announced it was reviewing its UK operations earlier in the year, with jobs cuts, but said operations at Cardiff would be unaffected.
The airline says today's announcement reflects its "commitment to expanding further its operations to and from the Welsh capital."
The Welsh Government announced bought Cardiff Airport in March, and pledged to turn it around after falling passenger numbers in recent years.
