Cheap flights from London to Shannon

Ireland's summer drives demand here: June through August, along with the school-holiday weeks, usually lift fares, and the Christmas and New Year stretch does the same. November is the month the calendar prices lowest on this route, so flexible travellers aim there. Midweek departures tend to undercut Fridays and Sundays, but check the month view rather than assume. The calendar carries prices for the full year, October through September, so test a few months against each other before you book.

What the fare includes is where the carriers split. Ryanair and Easyjet quote headline prices that cover little beyond a small cabin bag, with hold luggage, seat choice and priority boarding appearing as paid extras. Aer Lingus and British Airways sit on the full-service side, charging more up front and bundling more of that in. Air France, Austrian, Lufthansa City Airlines, Eurowings, BA CityFlyer and Malta Air also appear on the route list, some of them selling the trip with a change of plane — the itinerary shows which legs are nonstop before you pay. Weigh total journey time against the fare, not just the carrier name.

Shannon handles everything through one compact terminal, so walks from gate to kerb are short and queues rarely eat into a schedule. The airport sits on the edge of town, and the centre is a matter of minutes away by taxi or local bus. It doubles as a gateway to the wider west coast, and hire cars at the terminal are the usual tool for touring it — check desk hours and last bus times if you land in the evening.

Country facts: Wikidata

• Check whether a connecting itinerary is sold as one ticket or two, because a self-transfer leaves any rebooking to you.
• Ryanair and Easyjet treat bags as paid extras, so price your luggage into the total before comparing them with Aer Lingus or British Airways.
• London departures leave from five airports, so confirm which one your fare uses and how you will reach it.
• The UK and Ireland share the Common Travel Area, but you still need whatever photo ID your airline asks for at the gate.
• Fares climb through the Irish summer and the Christmas weeks, so book those dates early or move the trip to November, the year's lowest-priced month.
