Top tips for finding cheap flights to Canada

  • Morning departure is around 17% more expensive than an evening flight, on average*.
  • You can travel to Canada directly from several London airports, so make sure to check which is the most convenient one for you before booking. For example, you can fly to Calgary Airport (YYC) from both London Heathrow Airport (LHR) and London Gatwick Airport (LGW). If you are based to the west of London, Heathrow might be a better choice for you, whereas Gatwick might be more convenient if your point of origin is south of the city.
  • If you are flying to Canada during the winter months to go skiing, you should fly to Calgary Airport. It is located only about 1h 30min by car from Banff National Park, which is famous for its slopes.
  • As a UK citizen, you do not need a visa to travel to Canada, as you’ll be permitted tourist entry upon arrival. You must apply for an Electronic Travel Authorisation before you travel, though, and you must hold a passport that is valid for the duration of your stay.
  • If you decide to hire a car at the airport, it’s essential to be aware of the country’s road safety laws, especially if you have children in the car. Seat belts must be worn at all times in front and back seats, and children must travel in a suitable child seat.
  • For added convenience, you can use Heathrow’s Reserve and Collect online service to pre-order any duty-free items before you arrive at the airport. You can collect your purchases once you get to the terminal.

My new suitcase got busted when I arrived at Toronto , two of the wheels are broken and can no longer be used , I am very disappointed over this situation but the flight and service was awesome .

From what I saw there was no entertainment. Similar to my flight to London, I personally would like the attendants to be more interactive during the flight.

Air Transat left my luggage back in Montreal and it took them 5 DAYS to get it to Venice. Luckily I was still in town, or else their option was to send my luggage back to my house in CANADA. What a joke! Oh, and I had to find a way to go get it at the airport in Venice, they needed 72 hours more to get it to where I was staying.

I was pleasantly surprised. I booked the "club class" which was basically like Domestic First Class. The service was superior. Food was pretty good. Seats and cabin were comfortable. For the price I paid, I was very pleased.

Super unproffesional flight . Flight attendants were unproffesional. I could hear them gossiping about theor boyfriends the whole trip

The connecting flight lay over was 4.00 hours, the gate agent booked me on the next flight which was about to depart at no extra cost.

The ticket price was reasonable, food was okay, not the best. I would use the service again.

Actually the flight was on time. New plane, food was okay but not great.

Old plane, hard seats, 1.30 hours delay, while seating on the plane waiting for departure.

Great boarding. Everything was on time. Plane was a bit old and the crew could have provided better drink service.

Delayed by 4 hours. Missed connection back to UK. Ended up 24 hours late with an overnight delay. Westjet offered hotel accommodation but when we got to the hotel they said it was fully booked. Terrible experience

Over an hour late. Lousy flight attendant who was just going through the motions in every aspect of her job. The Dash 8 aircraft is super basic (no entertainment system, small seats, limited storage). Carry on luggage doesn’t fit in overhead bins.

4 hour delay leaving Paris. Didn’t get to board through jetway. All of the passengers had to take busses from the terminal to the aircraft. Once we got to Calgary, we had a very long layover that was shortened significantly by the big delay leaving Paris ( when I originally booked the flights, the layover in Calgary was 3 hours, a month before the trip, WestJet changed the second flight which increased the layover to 8 hours!). The flight from Calgary to Nanaimo (ya, the one that they already bumped back by 5 hours) left over an hour late. So, instead of arriving home in Nanaimo at 2 pm, we arrived at 1am. It totally sucked.

Okay but not like typical first or business class. On domestic airlines

Hey it got me from A to B on time on a crazy day. No food is offered in board No entertainment options And worst of all, no communication regarding baggage claims in Atlanta!! Having precleared CBP in Canada and landing at a domestic gate I expected to pickup baggage at the domestic terminal. No indication in app of where to pick up bag. No text message from WestJet. So I went to domestic where my bag was NOT. Do you know what a pain it is to get from domestic terminal to international at ATL? 45 min ordeal. My bag was still on the carousel, along with many other WestJet bags from mine and other flights. I pity any arriving customer not familiar with ATL trying to find their bags in this circumstance. And then no way to catch Marta from international. This falls far below the standards expected of modern airlines.

The flight attendants were amazing. But we checked in online and just needed to check our bags. The line was so long that it took over an hour to do this. There was only one person checking people in.

I liked the kindness of the check in counter crew, the flexibility with changing seats and the comfort. Better free drink selection would have been good but it wasn't a long flight.

Did not realize this was a super budget airline - we even had to pay for a carry on!

Slow boarding process, tickets downgraded to Ultra Basic with no carry-on luggage, not enough space in overhead compartments

All was good except that the option to purchase wifi for texting throughout the flight didn't work. My partner and I both tried via the app, Chrome and Safari, we tried all payment options. Nothing worked. He was able to get ok blonde with he full coverage option, but it's nice to what we wanted or needed.

Automatized Check-in process still has many problems. The online system continuously fails. At the airport the baggage drop off with the automated systems had many hiccups and diverted many to the manual desk, which is now only one desk! For me it meant standing in two long lines just to drop off a bag. Staff was friendly, food quality on board has been better with Swiss, specially on outbound flights.

Easier to get to the Wi-Fi they should give more snacks and ask if you want more drinks and I think nuts would be better than cookies

Do not book a flight thru Toronto Pearson to the US with less than 2 hrs between connecting flights. With 90 minutes (which I had) if your first plane is 25-30 minutes late by the time you debark, walk to go through security again, go through US customs and find your new gate with at least 15 minutes before your departure. If you stop to go the the bathroom you will be lucky to catch your flight, in my case I wasn’t lucky. The airline should not offer flights that do not allow you time to get to your second plane, bad customer service!

It was swiss air flight and they were very helpful and kind

Hard to criticize after the Crowd Strike dilemma. However, when Air Canada says they were "not affected," I expect that is true. My flight delays caused me to miss transportation connections. I understand these things happen, but I don't have to "like it."

My flight was delayed in Calgary and I missed my connecting flight to Cincinnati. I was rebooked on a flight the following day. I did not receive a food or lodging voucher.

I paid premium economy and I found out there is no premium economy in Europe, so why they charged me premium if that service doesn't exist???

It's unacceptable to receive your bags after 5 days, and having to call multiple times to get delivery.

Flight was canceled 2 hours ahead. Just as I arrived at the airport

There was no entertainment on board and wi-fi did not work for me. Food consisted of beverage and pretzels. Flight was over 2 hours delayed due to unscheduled maintenance. We missed our Toronto connection. Air Canada rebooked us for the next day. We had purchased premium seats but our rebooked flight was nearly full and we did not sit together. Seats were way in the back of the plane. Air Canada did provide us with a hotel stay. Agent upon deplaning told us luggage would be sent through to our final destination. Customer service person told us our luggage would be at the carousel. It never showed up, so we lost an hour waiting for it, already well past my bedtime by now. My husband has limited mobility. Baggage agent advised us the luggage did, indeed, get placed somewhere for our next day flight and provided us with an overnight kit (shaving kit, oral hygiene kit, sleep shirt, etc.) and it was very much appreciated and needed. Husband has mobility issues and we found that wheelchair assistance is not provided during layover stops, which made it difficult (and slow) for us to get from gate to customer service to baggage claim to hotel shuttle. We were given food vouchers but were too exhausted to use them before going to hotel. For the most part, all agents we dealt with were respectful and pleasant, although only a few were as warm, friendly and helpful as most of the Canadians we had interacted with during our visit.

Boarding was haphazard after people with small children or walking difficulties

No internet, very narrow seats insufficient room for three passengers with encroachment.

Due to flights being delayed, we missed our connecting flights and we were flown to a different airlines and we end up losing our luggage's.

The boarding process is not well organized at all. It need to be totally revised with an emphasis on order.

full flight, could use more room....leg room fine seats tight

Other than problems with checking in and uploading passport info everything was great. It would be nice to be able to manually input passport info. Often while traveling the bandwidth has problems uploading pictures

Give at least coffee or juice as it is an international flight.

Tiny, cramped seats with minimum leg room and hard armrests. Basic needs like a seat and luggage came with an additional charge. Budget airline amenities with premium airlune cost. I won't use this airline again.

Cancelled flight, that morning! But got us on an Air Canada flight!

Boarding process non existent. No WiFi. No entertainment. Cramped old plane. Worst Kosher meal ever presented on a flight.

Usual friendly BA crew who were helpful and so kind to the kids. New business class cabin combined with 787 makes for a really enjoyable experience.

Overall flight experience was good. Unfortunately our process getting to our flight was a hit or miss. Our flight was delayed perhaps for the best as getting from terminal to terminal is very long and security had problems with the machines that delayed us getting to our flight. Heathrow security could care-less that you have a flight you are about to miss!

Horrible. Crew is not helpful. Lounge is sub standard and overcrowded. Getting to your plane is underwhelming “via a bus”. Worst experience I have had.

I liked nothing, my connection was missed after a 6hr delay, 3 of those hours were spent trapped on the tarmac going nowhere. They rebooked me with a different airline for the next day but never confirmed my seat, so I had to wait another entire day… after walking around an airport for the whole first day waiting for the front desk to open to get my ticket. A 19hr trip turned into an 80+hr trip. Of course, British airways has no actual customer complaint phone line, so I have heard nothing at all from the airline. Oh, and they lost my bag. This trip cost an additional $3000, several days of missed free time, and some agonizing discomfort from so much wandering around airports and venice trying to find replacement clothing. This sucked.

The online flight scheduler only assigned 3 hours to get from Gatwick to heathrow. This is not enough time for a normal transit between the two airports. I had to run and hire a taxi because the bus and train would take too long. After paying a 150 Taxi I arrived at the gate just before it closed.

Our flight BA638 was cancelled with very short notice. It was supposed to depart at 7:25am. We had left Chichester at 3:30am in order to make the flight, and we were notified of the cancellation while en route to LHR. We were told the cancellation was necessary because a plane had not been scheduled to be at LHR for this flight! We were rescheduled to BA636. This flight was supposed to depart at 11:00am but didn't actually take off until ~12:30pm. Consequently we arrived in Athens several hours late, missing out on half a day of our sightseeing time. We had booked transport with MyTransfers to pick us up at the Athens airport and drive us to our Hotel Adonis. I was unable to get a refund for this service because our flight was so delayed. They required 24 hour notice of pick up time changes. I instead had to pay for a taxi at the airport. I have tried to fill out a request for compensation online but have been unsuccessful. How can I get help for filing a claim?

I had to wait for 10 hours at the airport and no hotel accommodation was provided. That sucks big time.

They can't seem to deliver a delayed bag in less than a week. Is this the 19th century?

Initially there was delays due to weather so we were grounded. Once we got off the ground, they were quick to turn of the seat belt sign and give us drinks and snacks. No complaints about the flight. It was very full.

We're waiting an BA flight being operated from London to Raleigh
