Cardiff, being a vibrant international city, is served by its own airport, Cardiff Airport, located on the outskirts near the village of Rhoose. As the only airport offering international flights in and out of Wales, it plays a crucial role in connecting the region globally. At present, the airport is owned by TBI PLC and serves over one million passengers annually, acting as a hub not only for Cardiff but for South and East Wales as well.

Cardiff Airport is a base for major travel operators such as Thomas Cook and Flybe, with flights to popular destinations including Malta, Amsterdam, Zurich, Dublin, Newcastle, and Aberdeen. It also offers regular routes to various destinations in Spain and Greece, such as Rhodes and Mallorca.
