Cheap Flights from Dublin to Montreal

Fares on this route touch their lowest point in November, and dated prices are listed for every month of the year, so the shape of the season is easy to read before you commit. The peak summer weeks and the days around Christmas and New Year sit at the top of the range, when demand peaks on both sides of the Atlantic.

Midweek departures usually price below the Friday-to-Sunday rush, and the shoulder seasons — late spring and early autumn — pair kinder fares with kinder weather in Montreal. Winter travel asks a little more planning: the city is properly cold, and snow can slow the final leg into town.

Full-service network carriers dominate the mix: Air Canada, United Airlines, American Airlines, Swiss, Turkish Airlines, and Lufthansa alongside its short-haul arm Lufthansa City Airlines. The leaner side is smaller — Air Transat, Air Baltic and Transavia France — and no airline on the list flies Dublin and Montreal nonstop, so a connection is part of every ticket.

What changes is what the fare includes: the network airlines usually fold a checked bag, a seat and a meal into the transatlantic ticket, while the low-cost and leisure names sell those pieces separately, so judge each option on its total cost. With every itinerary connecting, the layover matters as much as the fare.

You land at Montréal–Pierre Elliott Trudeau International, which sits west of downtown Montreal, close enough that the ride into the centre stays short. A dedicated bus links the airport with the city, and taxis and ride-shares queue outside arrivals, so the last leg is easy to arrange at most hours.

Two things are worth planning around. Montreal is a French-speaking city, so airport signs and announcements come in French first, though English is widely understood. And in winter, snow and ice can slow both the drive into town and any onward journey the same day, so leave slack in your plans.

Country facts: Wikidata

• Check whether Canada requires you to hold an eTA or a visa before you fly, and have the approval sorted before you pay for the ticket.
• Every itinerary on this route includes a change of plane, so check the layover length before a fare starts to look like a bargain.
• If your booking is on two separate tickets, the second airline is not obliged to rebook you after a missed connection, so favour one ticket where you can.
• On Air Transat, Air Baltic and Transavia France, a checked bag is usually an add-on, so price the bag in before you compare.
• Fares dip in November and climb through the summer weeks and around Christmas, so a flexible month can matter more than a flexible day.
