Cheap flights Cardiff to Paris

December is the cheapest month on this route, and the winter months around it — November, January and February — stay close behind. The price calendar here shows fares for September, October, November, December, January, February and June, so compare those before you commit. Midweek departures tend to undercut Friday and Sunday flights, when weekenders fly out and back. Skip the days around Christmas and New Year if your dates are flexible, and watch French school holidays, which push both airfare and hotels up. For winter trips a few weeks of lead time is usually enough; for June, book earlier.

Four carriers serve this route: KLM Royal Dutch Airlines, its regional partner KLM Cityhopper, German Airways and Aer Lingus. None of them is a low-cost airline in the strict sense, so the choice is less about paying for extras and more about which hub you connect through and which fare family you buy. KLM and KLM Cityhopper sell the same ticket types, while Aer Lingus brings its own cabin and baggage rules. Because nothing on this route is direct, the connection matters: keep both legs on one ticket and the airline looks after you if the first flight is late, while separate bookings leave you to sort out a missed plane yourself. Check what each fare includes before comparing totals.

Which Paris airport you land at shapes the last leg of your trip. Charles De Gaulle sits north-east of the city and has the quickest rail link in, with suburban trains and shuttle buses between terminals. Orly is south of Paris, with an automatic shuttle train to a suburban rail station and a tram link into town. Beauvais Tille is the odd one out: it lies well outside Paris and is used mainly by charter and low-cost traffic, so plan on a coach transfer that takes far longer than the other two. Whichever you land at, check the airport on your booking before you leave home — the three are not interchangeable, and moving between them eats a big part of a short break.
