Dublin is Ireland’s biggest flight market, so cheap fares do appear regularly, especially on short European routes. But low headline prices are uneven: school holidays, bank holiday weekends and peak summer push demand up fast, while quieter periods can open better value. If you can stay flexible on travel days and airport choices, you usually give yourself more room to find a stronger fare. From Ireland, that often matters more than chasing one airline or one exact departure time.
Know the usual Europe price windows
For Europe breaks from DUB, the best value often shows up outside obvious peak periods rather than at the very last minute. Short-haul fares tend to harden around school holiday demand, midterm break, major sporting weekends and popular sun dates. If your travel period is fixed, start tracking early so you can see whether prices are drifting up or briefly dropping. Reisedrop’s price alert and drop approach is useful here: watch fares, then book when the timing actually improves instead of guessing.
Use the midweek trick properly
Flying midweek can help, but the real trick is broader than simply choosing a Tuesday. Lower fares often come from combining a midweek outbound with a midweek return, avoiding the busiest Friday and Sunday patterns. It also helps to compare very early departures and later evening flights, which some travellers skip. If you are planning a city break, shifting your holiday by even one day can change the fare structure noticeably from Dublin, especially on heavily competed European routes.
Budget airlines: the baggage trap is real
A low fare from DUB can stop looking cheap once baggage rules are added. Budget airlines often separate the base fare from cabin bag size, priority boarding, seat selection and checked luggage, so the cheapest result on screen may not be the cheapest trip in practice. Always price the journey with the luggage you actually need. If you are travelling with gifts, sports gear or winter clothing, this matters even more. For many travellers, one realistic fare beats an artificially low headline fare.
When Belfast is worth checking
Belfast can be a smart backup when Dublin prices are stubborn, particularly for direct European routes with strong competition. It is not automatically cheaper, and the savings can disappear once you factor in transport north, parking, timing and the value of convenience. But if fares from DUB stay high around busy holiday periods, checking BFS and BHD can widen your options. This is most useful for travellers in the north-east or anyone already combining a trip with Northern Ireland.
Compare the full trip, not just the ticket
The cheapest flight is not always the best value once you include airport transfers, baggage, overnight timing and flexibility if plans change. Dublin usually offers the widest choice, but more choice also means more fare types and more fine print. Compare like with like: same baggage, same payment assumptions, similar flight times and realistic onward transport. That gives you a clearer view of what is genuinely good value in Euro terms, rather than what simply looks cheapest in the first search result.
