Carcassonne is served by Ryanair with planes arriving from London Stansted, Edinburgh, Glasgow, Manchester, East Midlands, Dublin, Cork, Porto and Brussels Charleroi. Please note that some these flights are seasonal. In the summer RyanAir flies 14 planes a week from London Stansted but only three in winter. Prices can vary but we have flown for as little as 19 Euros a seat, provided bookings are made in good time.
