Cheap flights from Dublin to Prague

January is the cheapest month on this route, and the price calendar covers the whole year, from September round to August, so you can see how each month compares. Summer and the run-up to Christmas are the busiest stretches in both Dublin and Prague, and fares follow that demand; spring and late autumn sit in the middle. Midweek departures and early-morning or late-evening flights are usually the quieter ones. If you are set on a particular date, a Christmas market weekend or a summer break, book well ahead, because the seats that cost least on those dates go first.

The airline mix on Dublin to Prague splits into two groups. Ryanair, Emerald Airlines and Smart Wings sit at the low-cost end, where the ticket covers your seat and a small cabin bag, and anything checked or chosen in advance costs extra. Aer Lingus sits between the two, so read what your fare includes. KLM Royal Dutch Airlines, Air France, Scandinavian Airlines, Norwegian and Norwegian International are full-service, usually with a connection in a home hub and a different baggage allowance. Transavia France is a low-cost carrier that often turns up on one-stop itineraries.

Flights land at Prague Ruzyne, the city's airport, which sits outside the centre rather than in it, so plan a transfer rather than a walk. Buses and airport express services link the terminals with the city, taxis and ride-hailing apps wait at the kerb, and the ride in is short enough that most people head straight to their hotel. Check which terminal your flight uses before you arrange a pickup, and agree the fare or book through an app before you get into a taxi. Landing late at night? Confirm your bus or shuttle still runs at that hour, because schedules thin out overnight.

Country facts: Wikidata

• Dublin has a single main airport, so check that the departure airport on your booking matches it.
• On low-cost tickets, add a checked bag and seat selection to the total before you compare it with a full-service fare.
• If your connection is on separate tickets, leave a long gap and remember the second leg will not wait for a delayed first one.
• Check the entry rules for the Czech Republic and that your passport or identity card is valid for your travel dates.
• January is when fares dip, so if your dates are flexible, start there and work outwards.
• Book early for summer and the Christmas period, when both cities fill up.
