Top tips for finding a cheap flight from Boston 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.

I love the 2 seats per row. More room. The crew were excellent.

It was amazing although they did bump us up to the front which gave us more leg room and a meal. The service was great! The staff were friendly. :)

Overall very good... staff were friendly and helpful. boarding was good for the most part, but a little hard to get our carry-on bags on there.... I think people should be directed to keep their coats and small bags with them until all the carry-ons are loaded, and then, if there is space, they can put their small bags and coats up top.. makes it much easier to put baggage up. i loved the internet feature, but the entertainment was not there unless you have your own Netflix or similar platform. My chair did not recline, which was very annoying, and the arms won't go up near the isle, which makes it tough to get in and out of the seat.

Staff were excellant. Only snacks served. Some turbulence so we were offered Free beer or wine.

The staff is always great. Just the fact that our flight was the only one delayed from Halifax when all other carries were still flying. It happen a year ago out of Toronto as well. All others were flying but our flight got cancelled 1 hr before the time of departure.

The only issue had when i mentioned about comfort was the man beside me was on the larger side and took about 1/3 of my seat where i was pressed against the wall/window of the plane for the trip.

The check-in staff, boarding staff, and flight crew were all very friendly. Really miss the Porter lounge in Ottawa.

Thanks for giving a beer to everyone in the seat infront of me and then telling me that I can’t have one because they are going to land. I guess I need to pay for a seat and then pick one in the very front of the plane

The flight was delayed by more than one hour. The terminal was consequently overcrowded and hot. We lost our car reservation and hit rush hour traffic in Boston, which added two hours stuck in traffic to our trip.

Awesome, the whole way through. Thank you, this is the new Canadian Airline benchmark.
