Good news for travellers planning a getaway to Ireland this autumn or winter: Aer Lingus is currently offering up to 30% off a selection of European flights to Ireland.
The offer applies to travel between 1 October 2026 and 19 March 2027, with a booking deadline of 17 September 2026. It is a short window, then, but one that could make it worthwhile booking a weekend in Dublin, a stay in Cork or a reduced-price arrival through Shannon.
Aer Lingus cuts fares to Ireland
Up to 30% off for European travellers
The Irish airline is advertising discounts of up to 30% on a selection of routes to Ireland from several European cities. As with this type of promotion, the best fares depend on the dates, departure airport and availability at the time of booking.
For French travellers, the appeal is clear: Aer Lingus flies to Dublin and Shannon from France, with one-way fares dropping below €40 on certain dates.
For example, the airline is currently showing fares of around €38 one way between Paris and Dublin and around €39 to Shannon during certain periods. Prices change quickly and are, of course, not guaranteed for every date.
Which dates are included?
A promotion designed for autumn, winter and the end of the season
The travel period runs from 1 October 2026 to 19 March 2027. It is a particularly appealing time to discover Ireland out of season, when cities are less crowded and accommodation rates can be lower than at the height of summer.
This period includes the All Saints’ holiday, Halloween in Ireland, the festive season, winter weekends and the first breaks in March.
Paris, Dublin, Shannon: which routes should you watch?
The best fares are not always to Dublin
Dublin is naturally the most obvious gateway, but it can also be well worth comparing fares to Shannon. For a road trip in the west, the Connemara, Clare, Limerick, Galway or along the Wild Atlantic Way, arriving in Shannon can sometimes save several hours of driving from Dublin.
The advice is simple: compare the different arrival airports before booking. A difference of a few euros on the ticket can sometimes be offset by a much more logical itinerary once you are there.
Should you book now?
The 17 September deadline is approaching quickly
The promotion is only available for a few days. For those already planning a trip to Ireland between October and March, now could therefore be the right time to check the fares.
However, it is best to avoid booking simply because a fare looks low. You should also check the conditions of the fare you choose, including the baggage allowance, any change fees and the flight times offered.

A good opportunity to plan an off-season trip
Dublin, Cork and western Ireland become more accessible
For Guide-Irlande, this promotion comes at a particularly appealing time. Autumn and winter offer a chance to discover another side of the country: cosier pubs, less crowded cities, more dramatic landscapes and a stronger local atmosphere.
For those hoping to travel on a smaller budget, keeping an eye on flights now could help secure transport before planning the rest of the stay around accommodation, sightseeing and getting around once there.
