Top tips for finding cheap flights to Canada

  • On average*, there is no price difference when choosing to fly in the morning or the evening on this flight route.
  • 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.

My tv was broken on the flight which is disappointing when you pay for a seat and expect a service

Always delays from Boston to Salt lake but this time was very long. Don’t understand while they board the passengers and then make them sit in the plane

The boarding and flight were ok, but there were several painful issues. The flight was 3:20 in the air and almost four hours door to door, but they only had snack packs on the plane. They really need to have food on longer flights or make it clear to everyone that they won’t have food. They also advertise free WiFi, but it did not work for 90% of this flight. Again, almost four hours door to door. If I had known I was flying spirit for JetBlue prices then I would have planned differently.

Service for food to our seat was a bit slow. Snack choices were just pretzels or baked chips. My seat cushion was not attached. Other than Barbie, video choice were not very good or current.

After we landed, we were held on the plane for 30 minutes. There was no one at the gate once we landed and we forced to sit on a plan that had already over an hour delayed.

almost 4 hour delay as they over booked and had to wait for 8-10 volunteers to agree to travel next day.

Old plane. No outlets for laptop or phone. Seats worn out. Area around seat dirty.

I loved the flight and the crew. It was comfortable and smooth.

The crew was openly hostile and condescending to the customers. They spent the majority of that time in the rear talking and seemed really agitated when people asked questions. I heard five different people told that the information they requested was in the handout or safety brief.

ticketing issues caused many customers to have to go back to check in after waiting in security, then go through security line again.

If they have a tv for movie or map during 5h flight could be better and the food can purchase on flight are ok with that.

We requested 2 wheel chairs upon arrival. On board an attendant told us to remain in our seats until everyone was off the plane. we were in row 11 and thought we would be off early. After all were off, a different attendant said we should leave, and that the chairs were gone. One was available for my friend who had just spent 9 days in hospital but I had to walk quite some distance. Eventually a cart arrived to take us the rest of the way. This was over an hour after our arrival. The staff at the terminal did their best to help us but if we had been allowed off with the other passengers, our ride home would have been an hour earlier.

Our flight experience was great! Flight staff was funny and offered great service. Made record flying time coming home from Vegas after having to wait for planes on the tarmac because of high winds

Seats can use more cushioning, it felt very hard. The snack option could be better

Over all good. I had some issues with trying to buy my seat. The Westjet system kept trying to charge my credit card, without getting the seat. In the end after 5 times being charged, I got my seat.

I did not have a meal or entertainment, but flight was comfortable, beverage service was quick, crew was very helpful and pleasant. And a very smooth flight overall.

Flight was on time! Downloaded the entertainment app in advance - worked well

I liked when we actually were allowed to get on the airplane back to Edmonton… What could’ve been better well, not having our flight be delayed five hours could’ve been better… And then canceling our flight from Edmonton to Toronto, and then rescheduling us to fly from Honolulu to Edmonton -Edmonton to Vancouver, and then Vancouver to Toronto with a 12 hour layover in Edmonton pretty much was hell… Total travel time to get home 38 hours that’s really what could’ve been better. The two gate attendants for WestJet in Honolulu told us to come back to the gate to try to make other arrangements because they had to board the Calgary flight 1st and they didn’t have time to talk to me but by the time I came back when they told us to they said you should’ve come earlier to make these arrangements everyone else already changed their flights… We found out later that 30 people did not get on the 2:30 AM Edmonton flight. They ended up getting on the midnight flight to Calgary and making other arrangements to Toronto and so forth which we could’ve taken advantage of that if they had allowed us to when I initially had went up and approached the two gate attendance one of their names was Denise. One of the kindest WestJet employee was the one who received us in Edmonton, who felt so bad about the entire situation she got us for more meal vouchers and flew us first class from Vancouver to Toronto. In Honolulu they had given us two vouchers to use for dinner and they weren’t valid outside of Canada so we had purchased a meal and they were completely useless… But nowhere did it say that they could only be used in Canada So when we received more food vouchers in Edmonton, all of them did end up working in Canada, but it was just so convoluted. Overall, we have traveled to other countries even going as far as Africa… and that experience was far easier than flying to Hawaii from Canada I cannot believe any of this happened and how inconvenient it was We arrived, exhausted after 38 hours of travel, and could not even go to work on Monday. I look forward to hearing from KAYAK or from WestJet for some sort of compensation over the situation.

Delta gave out earbuds for in-flight entertainment, which was nice. But the legroom seems to decrease every year.

Flight late …60 minutes No food No wifi No entertainment system A disaster!!!

Aircraft has better leg room than any of United's larger planes. We had requested mobility assistance for this and related flights. United's response to all was superb.

No snacks served! Seating in the kast row in uncomfortable.

The flight and crew were fine. The entertainment- the sound was so bad through the headphones I could barely understand it and it was a show I had seen before. The food might have been fine but having to have an account with united in order to access the app in order to pay for the food was rage inducing. I had entered my credit card info at home and logged in as guest but that wouldn’t allow the “wallet” tab to open in the app. And then the wifi was so bad that it took about 45 minutes to fully log in and get all the info working at which time I missed the food. You shouldn’t have to give your address, email and phone number in order to get a hamburger.

Flight was fine, it was delayed but only 30 minutes, staff were efficient, lady making announcements at LAX was really hard to understand but the rest were great.

The male air hostess was rude and didn’t even offer me a drink. Poor customer service!

We left really late. Things that were out if anybody’s control I guess.

There was no in seat entertainment, you had to spend $10 on their wifi which worked poorly at best. You were allowed ONE one oz snack for a 3.5 hour flight. Seats were made for midgets. I am a regular size adult male and I had to wedge myself in. Not a fan.

When I purchased my ticket, I assumed it was a real ticket, as in, when I go to the airport I am guaranteed a seat. Not so. When I checked in 24 hours ahead of time, I noticed I did not have a seat assignment and my boarding pass said "Standby." I was informed at the gate that the flight was full and I may not get on that plane. I don't recall being offered the option of selecting a seat when I checked in, and apparently, for the honor of pre-selecting a seat, you must pay an additional fee. So, a ticket really isn't a ticket, it's actually a lottery and if you're lucky, you may make it on board - or you can choose to be extorted for extra money for the guarantee of a seat. It's like making reservations with the Godfather - one payment isn't enough, there's always another bribe you have to make. After the first few zones were called and I hadn't been informed of my status, I went to the gate agent and they handed me a boarding pass, for the very last row near the restrooms, in between two very large people. Apparently that was my punishment for not purchasing a seat ahead of time. Airline service has not only gotten more expensive, but the return on your money has shrunk and there is little regard for the passengers. This feels like a racket. I am not pleased, as you may have gathered.

It was your usual flight. Nothing exemplary. Due to turbulance, the drinks were served 20 min before landing. Meh.

My only concern was that we were on the tarmac for so long and weren’t told what was happening. It turned out that the system needed to be restarted but it would have been nice to know earlier.

Flight was smooth and comfortable. The crew were exceptional. Amanda, Nichole and Hershel were attentive to our every need. So friendly. My daughter and I were surprised at quality of service. Loved the double row seating. Snacks were delicious. We would definitely fly with Porter again. Flight PD 670 SFO to YYZ Thank you so much for the best flight experience we have had

The E195-E2 is a great aircraft! Leather seats, lots of legroom and SO quiet! The flight crew is terrific!

Check in was slow because of passenger ahead in Reserve line. Seats were somewhat uncomfortable.

Delayed by 2.5 hours. This happened previously on my flight from YOW to YVR on Dec. 26.2023. This is a terrible airline. The reason was there was lack of ground crew. This is a known event. AVOID PORTER AIRLINES IF YOU CAN. There is a reason half the plane was empty.

Flight delayed 6 hr. Looking for compensation and will claim for it.allow US people to fix to avoid huge delay having a canadian tech to fix it.

I didn’t make my flight due to poor weather and I had an accident driving there. I tried to get my money back or even credit and nothing. I have an entire flight both to Florida and back that I paid for and no one will give me any money back. I know this isn’t just Porter and it’s 3rd party- however airlines should allow these companies to take money for things they don’t get. I’m so upset. Who can afford a full flight they never take?

Flight Ottawa to Toronto canceled and no crew was available to direct me on what to do. I opened a file and I wait to be compensated.

New jet. Lots of leg room. On time departure. Early arrival. Reasonable airfare. Excellent online experience.

I had checked in online the day before but was instructed to collect our boarding passes when we arrived. I am not completely comfortable using the automated Kiosks and always enjoy the nostalgia of speaking with someone when checking in for a flight. Upon doing so however, we were immediately asked,"did you check in online already?" To which I replied, "yes, but we were asked to retrieve our boarding passes upon arrival." She then said, "that's what those machines over there are for. We really encourage people to use those." That unfortunately sparked a series of shortness and overall poor behavior in my opinion from the woman who checked us in. I understand it was early in the morning but I am always excited to experience flying and that interaction has unfortunately left a bitter taste in my mouth to the point I will forever now hesitate to book with Porter again. Thank you for taking the time to read this. Cheers, JD

Everything was fantastic, by far the best airline experience in Canada 🇨🇦!

My flying experience with Air Canada was good but the wheelchair situation wasn't good at all and if would be good to make sure that they have the appropriate services available for your traveling passengers.

All of our flights got delayed. Fll-Montreal delayed due to technical issues. We got transferred to a Fll-Toronto flight, in Toronto flight got delayed 5 hours causing us to miss our connection to Amman. We are now arriving to Amman 24hours later

Flew in Business Class. The new AC lounge at SFO is one of the best I’ve been to with a spacious design and an open air deck. Flight itself was on-time and as expected overall.

In flight wifi that I paid for was very slow and at times didn't work at all.

It has space for legs. Comfortable seats Punctual Some snacks should be served

Air Canada staff needs to be trained in hospitality. Most flight attendants are with attitude. Air Canada needs to carry additional food on board especially vegetarian plates as this category of travellers are on the rise. This is necessary for long distance flights. Blankets are cheap. Seats are not designed well Lower back portion should be thicker. Everytime thr passenger at the back of me took stuff or put stuff in the pocket of the seat in front of them which is my seat, I could feel them pushing or hitting on my chair.

Flight delayed two and a half hours from Toronto to Calgary Philadelphia to Toronto we were listed as standbys !!! Very concerning

Flight delayed at the last moment Hill next day and havé to drag at Hotel at our cost and bec day was again delayed 4 Times because no crée and no pilot

The flight was more compact. The flight was more turbulent than usual. Otherwise no complaints.

No food, not even snacks on the 6hr flight from Newark to Vancouver! The movie collection made up for it though and they did come around with drinks twice. Just good to know so you can eat ahead/bring snacks onto the flight. It was a bumpy ride induced by wind and rain but otherwise got to the destination safely and promptly.
