Cheap flights from Shannon to New York

December is the cheapest month on this route, and the price calendar covers most of the year, from September through July. Winter travel outside the Christmas rush is usually the quietest and kindest to your budget, while summer and the weeks around the holidays push fares up. Midweek departures tend to be gentler than Friday and Sunday, when weekend traffic peaks on both sides of the Atlantic. Book well ahead for summer and Christmas, and later if you can be flexible in the low season — the calendar above shows what each date actually costs.

There is non-stop service between Shannon and New York, and the rest of the names on this route connect you through their own hubs — American Airlines, Delta Air Lines and United Airlines through their US networks, Air Canada through Canada, and Lufthansa and Eurowings Discover through Europe. Aer Lingus is the Irish carrier in the mix and worth checking alongside the rest. These are network airlines rather than low-cost carriers, so the gap between a cheap fare and an expensive one is usually the fare family and the routing: whether a bag is part of the ticket, and whether the whole trip sits on one booking. Compare the total journey, not the headline.

Non-stop flights from Shannon land at John F Kennedy, and connections can also put you into Newark Liberty International or La Guardia, so check which airport your fare uses before you arrange ground transport. All three sit outside the city centre, and none of them is a walk from Manhattan — you continue by train, bus, shared shuttle or taxi. Traffic can turn a short ride into a long one, so leave room in your plans if you have a connection onward or a fixed check-in. If your fare arrives at one airport and departs from another, plan the transfer between them before you travel.

Country facts: Wikidata

• Confirm which New York airport your fare uses — John F Kennedy, Newark Liberty International and La Guardia are not interchangeable for transfers.
• Check what the fare includes for baggage, since a low headline fare without a checked bag can cost more than a higher one with it.
• If the trip runs on two separate tickets, leave a generous gap between flights in case of a delay.
• Make sure your passport and any US entry authorisation are valid before you pay, and check again near departure.
• Book December if your dates are flexible, and compare the months either side on the price calendar.
