Cheapest months to fly to Knock
Knock doesn't see the same pricing chaos as Dublin or Cork, which is actually a good thing if you know how to use it. Fares tend to stay reasonable outside of summer, when Irish diaspora traffic from Birmingham and Bristol spikes hard — think June through August. The real pressure points are school holidays and any weekend tied to a GAA match or local pilgrimage season, since Knock Shrine draws serious crowds. January and February are typically the quietest, and that's usually where the cheapest seats hide.
Why visit Knock?
County Mayo is the honest answer to why people fly into Knock rather than routing through Dublin. The Wild Atlantic Way runs right through here, and the is genuinely dramatic — sea cliffs, bog roads, and Croagh Patrick looming over everything. The town of Westport is one of Ireland's most likable spots: proper pubs, good seafood, and none of the tourist-trap energy you get in bigger cities. Then there's Knock Shrine itself, one of Ireland's most major Catholic pilgrimage sites, drawing visitors from across Europe year-round. If you're into heritage, the region has Iron Age sites and Norman castles that most people completely overlook because they're too busy queuing in Killarney.

Tips for getting a cheap fare to Knock
February is my pick for the best value into Knock — low demand, and you'll actually have the countryside to yourself. If you're coming from Edinburgh, that route tends to price sensibly compared to flying into Dublin and renting a car west. Set a fare alert early and check it often in the three-to-six week window before you fly, which is usually when prices settle. There's no visa needed for EU or UK passport holders, and Ireland uses the euro, not sterling, so account for that if you're crossing from Britain. Booking Tuesday or Wednesday departures almost always beats weekend pricing.
