Top tips for finding cheap flights to Canada

  • Before booking a flight from Boston Logan International Airport (BOS) to Canada, figure out which part of Canada you want to visit. Those heading to Toronto will likely want to fly into Toronto Pearson International Airport (YYZ). Those wishing to go to Ottawa will want to fly into Ottawa Macdonald-Cartier International Airport (YOW). Meanwhile, Montréal-Pierre Elliott Trudeau International Airport (YUL) will be the best airport for those traveling to Montreal.
  • No matter which airport in Canada you would like to fly to, you should be able to find nonstop flights. Porter Airlines routinely schedules nonstop flights from Boston to Toronto, while Air Canada has nonstop options from Boston to Montreal. These airlines will get you from Boston to Canada in less than two hours.
  • Some airlines that travel from Boston Logan International Airport (BOS) to Canada won't offer you first-class accommodations. Porter Airlines, for example, is a budget-friendly airline that doesn't have first-class seating. Other airlines, such as Air Canada, have first-class seats. You should consider reserving one, especially if you end up on a flight from BOS to Canada with multiple stops.
  • If you plan to bring a carry-on bag aboard a flight from Boston to Canada, you can save money on baggage fees if you ensure that your luggage is within the size limits your airline has in place. Air Canada, for example, won't let any carry-on bags larger than 21.5 x 15.5 x 9 inches on flights. Porter Airlines, meanwhile, will only allow carry-on bags up to 22 x 16 x 9 inches.
  • Since a Boston-to-Canada flight is international, you must get to Boston Logan International Airport (BOS) at least two to three hours early. Once you arrive, feel free to kick back and relax in one of the airport's lounges, such as the Chase Sapphire Lounge, available to all Chase customers, or The Lounge, open to anyone willing to pay a fee.
