Cheap Flights from Shannon to Boston

Two calendars drive demand on this crossing. Summer is the big one, when school breaks put families on the route and fares climb with them; the Christmas and New Year fortnight does the same from both directions. St Patrick's Day is the holiday these two cities share, and the days around it tend to book up early. The quiet stretch is late winter, with February coming in as the cheapest month here, and midweek departures generally undercut Fridays and Sundays. The price data on this page spans October through July, so check your month before you settle on dates.

The difference you actually feel between these airlines sits in what the fare includes. Aer Lingus, Delta Air Lines and United Airlines are full-service carriers, with checked baggage, meals and a seat assignment normally folded into a transatlantic ticket, while Eurowings Discover is a leisure-focused brand that keeps the base fare light and prices bags and extras separately. Nonstop flights exist on this route, so read the flight details before you accept a connection; a lower price with a change means buying a stop at a hub instead of a straight crossing. Compare the total with a bag added, not the headline fare alone.

Logan International is a large airport with several terminals, which means real walking distances, shuttle buses between buildings and security lines that swell when long-haul arrivals bunch up. Everyone entering the US clears border control here on arrival, so leave slack in your plans for that queue. The airport sits close to central Boston, just across the water, and the usual ways in are the T by way of an airport shuttle bus, a water taxi across the harbour, or a cab or rideshare. If you take a car, mind the harbour tunnels at rush hour — the distance is short, but the traffic is not.

Country facts: Wikidata

• If your fare includes a change of plane, check whether both legs sit on one ticket — a self-transfer leaves you rebooking the second flight at your own cost.
• Baggage rules differ between the full-service carriers and the leisure brand, so price a checked bag into the total before picking the lightest fare.
• Sort your ESTA or visa for the United States before you book, and keep your return travel details to hand for US border control.
• February is the low point in the fare data, so summer and holiday dates will cost more and are worth booking early.
• If every option on your date shows a connection, widen the range — nonstop seats do exist on this pairing.
