Flights from Toronto to Heathrow: the best tips from KAYAK users' own experiences

Insights shared by verified travelers who flew the route from Toronto to Heathrow 
CFlew with Air CanadaFeb 2025
Flying from Toronto to London is a long-haul journey, but with the right preparation, it can be a smooth and enjoyable experience. Here are some tips to make your trip more comfortable: Choose the Right Flight – If possible, book an overnight flight (a "red-eye"). This allows you to sleep on the plane and arrive in London in the morning, helping with jet lag. Pack Smart – London’s weather can be unpredictable, so bring layers and a compact umbrella. Also, keep essentials like a travel adapter and charger in your carry-on. Use Luggage Tracking – If flying Air Canada, take advantage of their luggage tracking feature for peace of mind, knowing your bags are on the same flight as you. Stay Hydrated & Bring Snacks – Airplane cabins can be dry, so drink plenty of water. While airlines provide meals, it’s always a good idea to have extra snacks. Manage Jet Lag – Adjust your sleep schedule before departure and try to stay awake until nighttime in London to quickly adapt to the new time zone. Transportation on Arrival – Heathrow and Gatwick have great transport links. The Heathrow Express is the fastest way into central London, while the Tube (Piccadilly Line) is more budget-friendly. Have Your Documents Ready – Ensure your passport is valid, and if required, have your visa or travel authorization (e.g., an ETA for UK entry). With the right prep, your journey will be smooth and enjoyable.

the lounge is nice. Although the crew at check in will say there are no showers, there are! Check the board for delays

Pack light to avoid checked bag fees and then volunteer to place the carry on bag in the hold for no extra cost.

These are one of the older seat arrangements facing away from the windows! Not particularly convenient sets. No storage spaces. NO COAT HANGING HOOKS. Inconvenient business class seat compared to any other airlines of similar class. Staff are excellent! Extremely professional, friendly. Food is good too.

These are one of the older seat arrangements facing away from the windows! Not particularly convenient sets. No storage spaces. NO COAT HANGING HOOKS. Inconvenient business class seat compared to any other airlines of similar class. Staff are excellent! Extremely professional, friendly. Food is good too.

Overall, flight was excellent but check in was very slow for Premium Economy. Economy queue was shorter but we weren't allowed to use it.

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

Great crew - old style upper class seats on the older fleet now feels dated

Premium economy more comfortable than economy, but not by much. Did was awful, do not try the omelette. Flight crew were helpful. Flight was delayed by over an hour. Overall but bad, arrived safely and thank God.

Food was excellent. Service was very good. Staff was very helpful to all passengers.

The crew was excellent as ever on Virgin. The special meal was poor unfortunately. More significantly when we arrived at Manchester Airport there was no air bridge provided and we had to exit the plane down a rickety stair case. This is unacceptable for a transatlantic flight. Whilst I understand that this is the airport’s fault at the end of the day the airline is responsible for our transportation and needs to do something.

Super friendly and helpful staff, from check-in desk to cabin crew.

Following a paid seat upgrade for enhanced comfort, I encountered an unacceptable odor in my assigned area. It took three hours for the crew to relocate me, and the replacement seat was unacceptably close to the lavatory, offering no improvement.

Good overall. Cannot fault the airlines. I have had better entertainment systems before ie ice in Emirates but it was not too bad. Food was decent and staff were friendly.

Good service, friendly staff. Food was average for airlines and the seats were small.

Pathetic check in experience at JFK. Everything is self check in. Not enough staff present to help with when the check in process or the kiosk gets stuck. Staff present not welcoming or pleasant at all. On the other hand the NY based flight crew was great. Courteous and friendly throughout the flight. Special meals leave a lot to be desired. Kids meals should be made available when kids are flying and same goes for special kids meals too.

Flight was full, and would have preferred an aisle seat, but due to getting a late ticket ,the seat I had was adequate. The flight crew were very help full and hard working. Food and drink were excellent for the 11hr flight. Overall I was pleased with flight, and would recommend British Airways again.

More choices on menu. Seemed only thing offered was Scottish, and while that’s good for the Scot’s it doesn’t help the Americans who don’t like that food. And I really hate it when, during sleep time the attendants have a very loud conversation right over you. Lastly, I paid 5000 dollars for business class, and having to pay more to choose my seat early is really an insult. Seems greedy

The chicken adobo was a little too spicy but good otherwise. My personal opinion. Movie selection could be improved, too many horror movies. Could add a few more chick flicks! The flight was bumpy at times. We arrived a little early too! Flight attendants friendly.

Again flight was awesome except British Airways lost both gate checked luggage’s. Still missing

really bad they refused to check in luggages that I had purchased, even showing them the transaction receipt from british airways app the staff in miami was MEDIOCRE

Crew was great and responsive. Entertainment quit working with about 4 hours remaining on the flight. My seat cushion was broken.

Not very good , the stewardess were unfriendly and they don't like to be bothered. Cos was a night flight and they need to sleep.

British Airways staff are very polite and willing to help.

It was good to receive a card for my birthday

Horrible flight cancelled had to buy another very expensive ticket

Air Canada marooned me in Canada with no way back home during my summer vacation. I had to buy a last minute flight ticket for over $500 to make it back home. I have their credit card and have flown them for years. Never again.

Flight was cancelled last minute. Had to scramble and purchase a $2000 flight through a separate airlines. Stuck in Toronto two extra days. Missed my first two days on a new job. Had to rent a car for an additional two days. Scrambled to fins a place to live those extra two days. Spent a ton of extra money and lost a lot of money, as well as made a poor impression at work. Difficult difficult difficult

Terrible, return flight was cancelled a night before the flight was scheduled to depart and I was notified by an email and an automated message on their phone line. I’ll never book Air Canada again

It got cancelled and they haven't given me a flight back yet!!

Biggest problem for me is that I am Star Alliance Gold and they were not able to give me access to to Maple Lounge because of some computer glitch . It was management by information system. She could clearly see my status and still would not give me access because the computer woudl not let her. She should have override that be attentive to a customer and figure rhat out later

Great breakfast and coffee …..fastest bag service I have ever had in NOLA

Last minute cancellation, followed by last minute delay with the rescheduled flight. Both due to interval operation issues. Poor resolution.Very disappointing.

Late departing. Late arriving. More worried about limiting bags on board. Free beer and wine a nice surprise.

The plane (Mitsubishi CRJ) felt old, creaking and not very new. The crew was okay. Hot water provision was broken so hot beverages could't be served.

Horrible seats. They were just coach seats with the middle seat blocked with a dirty seat tray.

Not bad. We had preboarding tickets but the preboarding was badly managed. We lined up behind all the parents with little kids etc and when we got to the front of the line the attendant deliberately turned away from us and ignored us until I asked to be allowed to go to the gate. She started telling us that we had to wait until I told her we had preboarding then she let us through.

The plane delay due to a poor judgement of the pilot. It was the only flight that got delay due to fog.

Everything well done and customer oriented There entertainment system is difficult to navigate

They delayed my flight from Toronto Pearson for one hour and Frankfurt to Abuja for 2HRS, So sad

The aircraft was old, there was no charging sockets, and the seats were narrow and uncomfortable even though I had exit row premium seats.

The service was really good. The breakfast food could’ve been better as I don’t eat sweets for breakfast and the only choice was a muffin. Overall, good experience though. Thank you.

It was my first experience in business class. It was everything I expected and more. Service was impeccable, food was delicious and I felt rested once I arrived to London

The flight was delayed and I was stressing the whole time about whether I would make my next flight.

Last minute charge for 1 checked luggage before boarding which wasn’t mentioned when we bought the tickets months ago. It was an unexpected surprise. We had no choice but to pay to board. Most airlines allow your first luggage free.

In-flight service was very good. The entertainment system keeps resetting, it happened at least 7 times.

Boarding was efficient and quick, crew was very attentive, seats were comfortable.

The crew was friendly and helpful. The food was terrible.

Everything was very good! I personally struggled with the heat in the cabin for the first 2 hours

Terrible service especially for premium economy. Much more comfortable seats on other providers

Friendly hosts/hostesses; dinner was of acceptable, but mediocre standard

Very caring crew on board. Didn’t have dinner as I was sleeping. Was seating in the emergency row so I had comfortable leg room

Had a nice little suite although I couldn’t close the door (but I didn’t ask anyone to help). 5K is a nice seat and very private (you look in on first class). Enjoyable flight and nice crew.

Crew was excellent. And no surprise that the seats aren’t comfortable at all. But that is every airline.
