Cheap flights from London to Dublin

October is the cheapest month on this route, and the fares page shows prices for every month from September through August, so you can watch the year move. Late autumn and the weeks after the New Year are usually quieter than summer, when school holidays push Dublin fares up. Midweek departures, especially Tuesday and Wednesday, tend to cost less than Friday evenings and Sunday nights. Watch the calendar around Christmas and New Year, when people fly home, and around St Patrick's Day in March, when Dublin draws crowds. Book a few weeks ahead for an ordinary trip, and further out if you are travelling on those dates.

The route is served by a mix of low-cost and full-service carriers, and nonstop flights are available. Ryanair, Ryanair UK and Easyjet are the low-cost names here: the headline fare buys a seat and a small personal bag, and everything else is added at checkout. Aer Lingus and British Airways fly full-service, with a cabin bag and usually a checked bag in the fare, plus the option of changing a booking. You may also see Malta Airlines, Air France, Scandinavian Airlines, Norwegian International and Mokulele Flight Service in results, so check whether each itinerary is nonstop and what the fare includes before you compare totals.

Dublin has one airport, Dublin Airport, and it sits north of the city centre, a short drive or bus ride away rather than a long transfer. The usual ways in are the express and local buses and coaches that run to the centre and to the main rail and bus stations, plus taxis and ride-hailing pickups at the terminal. Allow extra time on arrival for passport or ID checks, which depend on your nationality, and for baggage if you checked a bag. If you land late, look up the last bus times before you fly, since the airport is not within walking distance of town.

Country facts: Wikidata

• Check which London airport your fare leaves from, whether that is Heathrow, Gatwick, Stansted, Luton or London City, before you compare prices.
• On a low-cost ticket, add the cabin or checked bag you need and see whether the total still beats a full-service fare.
• If a connection is on separate tickets, leave a long buffer, because a missed leg is not protected.
• Bring the right travel document for Ireland and check the validity rules that apply to your nationality.
• Book early for Christmas, New Year and St Patrick's Day, when Dublin fills up.
• Compare several months rather than your first choice, since October is the cheapest month on this route.
