I like WJ but I don’t like traveling anymore

Good flight. No I’m seat entertainment. But my phone worked just fine on the west jet app.

4 hour delay, lost our bags, staff was loud and it was an overnight flight

We were late boarding, but it all worked out. So, no problem.

It was good but not comfortable seat with the long legged persons.

No problems here. WestJet does a good job, even on their short haul flights

Boarding was fine, but then we were delayed a while due to some baggage issues, then de-icing.

Tried to reserves seats and WestJet My Trip shows not available until 24 hours before the flight. When check-in was finally available and I tried to get seats again I was not able to get to select seats for me and my wife together. All in all, was not able to select seats together on Kiwi, paid extra for seats on Westjet and still did not got seats together, not pleasant for such a long flight and with my wife not very good with flying, disappointed on the way the system works with regarding to seats reservations, even with paying extra for them.

Flight full. 'Volunteers' to check hand luggage. Checked hand luggage is lost

Not the fault of WestJet but we had to wait in the plane on the tarmac in Cancun for 1 hour.

Terrible boarding , Business class seats are sub standard. As usual crew will miss your food too

Just get Economy Plus for international flights, so worth it the extra room, bigger seats…

The return trip was a customer service disaster. American Airlines needs an overhaul of how they treat their customers.

Was flying in premium eco and there were around 5-6 movies I wanted to watch and none of those could I play for some reasons. Not just me we checked w the person sitting next to me. Few of the movies were only playable :( Also that was not great that we couldn't upgrade to business however tried to, many times before the flight :(

You cancelled my flight by email then made it very difficult to get in contact with you. Then put me in a flight with a long layover in Mexico returning to the wrong airport in uk. Mind blowing my stressful. I missed see my grand dad because of you.

This was not the BA business class it used to be. Mediocre food, attendants seemed stretched thin. All the little luxuries that used to make BA business fun were missing. Flight delayed and the explanation given was they forgot to pick up crew - I hope I misheard! Transfer in LHR “sticky” - we thought we had way too much time at 3hours but it was needed. Next time will try different route.

Flight from Phoenix to London was very quiet. Excellent space available for comfort, couldn't fault

Food was very average. And top up drinks offer was absent. For a 11 hour long flight that should be the minimum. The crew didn't want to be there. I understand it was new year day but given they had signed up for it

It was my fault choosing the seat nearest the entrance but it was ok.

It was good, the staff was friendly and it was a typical flight to Europe.

I think Air Canada is the only airline I've flown where they don't give you at least a free cookie.

The flight attendant bumped into me repeatedly time and time again, throughout the entire flight, preventing me from getting any rest. He seemed unaware of his actions and I was very close to saying something, but I didn't because I don't believe he would have understood or altered his behaviour. It was very irritating

All but one of four were on time. One was delayed for an hour

It took 5 hour to get a crew to D Ice the plan. We had to sit on the runway for 5 hrs. in Calgary. It snows most of the winter. No proactive plan. In addition, after 3 calls to customer service they couldn't figure out how to have my wife and myself sit together on her birthday weekend. Everybody kept passing the buck. No decision from customer service, luggage drop off or check in team. The experience was a complete mess! I don't think we'll ever fly on this airline again.

The wifi I paid for did not work. The seats are tight.

There were no free snacks…little pretzel bag or cookies like we had on our flight out.

Mostly crew good and the flight was safe and comfortable but service was lacking. For an overnight flight of 8hrs 50 it took some two hours to get served a drink and dinner after take off. I asked for Laurent Perrier champagne and was brought Perrier water, which I queried and asked where was the champagne. No response. The issue came up again an hour later when dinner was starting to be served and I was asked whether I wanted another drink, when I reminded I was still waiting for my first champagne! Apologies ensued but dinner service was quite slow. For breakfast I never did get served the hot course! So - no complaints and compliments on the safety of the flight but service underwhelming (and I brought them candies!)

Greetings to all the employees, they were very kind and welcoming. Excellent pilot, thank you for your efforts

The first leg of my flight from Toronto to London Heathrow was horrible. The seats in Economy are so tightly jammed together that any average height person is so uncomfortable. Going to the bathroom as well from the window seat was also a challenge as you need to disturb so many people to move out! The second leg to Vienna was delayed over 2 hours due to weather in Vienna but the LHR airport is so large that they don’t post the gate until 40 mins before the flight. So I had to run to the opposite end of the airport (zone B) to the furthest zone A gate. Took over 15 mins!!

On time departure with early arrivals. My last flight arrived 20 minutes ahead of schedule which was great due to my long commute home 3+ hours. The cabin crews on all 3 flights were great. See ya in 7 days Air Canada

Try to humanize onboarding and take AI out. It's embarrassing and useless

no kiosks to check in with- it’s 2024!!! the flight was so hot and uncomfortable - not sure if that’s what caused a lady to faint during the flight but i was absolutely miserable.

Air Canada from Edmonton to Toronto was disappointing but Lufthansa from Toronto to Frankfurt was excellent.

Overall good experience. Polite crew. Good foodandentertainment. Seats are small and bit congested though.

I ended up buying (for $340) "extra space" seats because I my flying partner was given a STY boarding pass, leading me to conclude that she was on standby and that we had to buy seats on the flight. I later learned that the flight was not sold out and that we could have gotten on as usual. To be honest, I felt swindled.

I'm Canadian. I have the unfortunate experience of pretty not having the choice to fly with them. THEY ARE TERRIBLE.

The process overall was pretty seamless, and the crew were very friendly (especially Michael). Considering we booked expecting Lufthansa and the flight was operated by United, it was still a very good service and journey overall. The in-flight entertainment was great, with lots of quality options. One slight negative was that I had selected a vegetarian meal prior to flying, but received a vegan one. I think there should be more dietary options as it meant I missed out on some food that I would have preferred (and it seemed like the standard meals and snacks had a vegetarian option anyway). There was also a group of people who were moving around a lot and being generally disruptive at the quietest part of the flight, when the lights were off and most people were sleeping. I would have appreciated staff stepping in to encourage them to be mindful of others). Towards the end of the flight (which was very early in the morning in both time zones), the lights suddenly came on and breakfast was served. In my opinion, this was too early, and everyone was rudely awoken from sleep. After breakfast was cleared away, the lights went off again for about 45 minutes, allowing people to sleep some more. Then the lights came on again for landing. It seems like if they had served breakfast later, the lights on-lights off-lights on shenanigans could have been avoided, and people could have slept longer (and staff could have rested longer too).

You only get a chocolate square and small bottle of water.!

to be bussed around the airport, then have to sit on the plane for an hour whilst the plane was deiced not once, but twice, then to have to wait for a tug driver is unacceptable. The Captain was very good at communicating.

Terrible. This airline will cancel flights at very short notice.

Food not so good. Need more veggies and whole grain especially the late food. Couldn’t figure out how to use the entertainment system.

Check in was horrendous! Economy took 2 hours before seeing an agent. Business class was 0.5 - 1 hour.

The first class flight itself was first class, however getting to the airport and getting through the airport was agony. The BA flight sat on the taxiway for ages and caused us to miss our connecting flight which meant half a day lost. Our return flight on BA was cancelled so a dawn flight was made and we lost another half day. Goodby BA

In economy and food was ok, but with limited leg space (and I was in a 2 seat configuration) it was difficult to eat with a tiny seat tray. I spilt wine on my trousers. First time on British Air (I usually fly Turkish Air) and in a 777. Heathrow was pleasant but changing terminals awkward.

Starting with the flight Cairo to London the plain was so poor no entertainment at all uncomfortable seats although it’s 5 hours long,then an American airline plain took me from London to Miami it was a bad experience the crew most of flight time not available and they asked us to help our selves for any snacks if we need. From Miami to London actually was perfect flight with a huge plain and perfect crew but from London to Cairo was horrible plain with stiff fixed seats not movable no entertainment or wi fi very poor Menu which is unacceptable for a business class

There was some delay at Heathrow where a machine needed to "start the engines" wasn't available and they couldn't even find the team tasked to do it. Unacceptable. Caused about an hour delay and seemed unnecessary. Also saw several passengers abusing the overhead luggage situation, having too many large bags and not leaving enough space for others. The crew was good and the refreshments were good in quality and quantity.

They cancelled our ticket, gave us no warning, they reissued it 4 days prior to trip and it was cancelled again when we got to the airport- very stressful, the flight was overbooked so they drove us across Milan to malpensa

I've done hundreds of flights in my life, and this flight was one of the best I've ever taken, From beginning to end, everything went smoothly, professionally, and with a smile and friendly attitude from all employees I interacted with. The food was delicious (and free), as were the drinks. There was just a genial and effective way in the way that British Airways organized the flight -that reminded of days in the 70's, 80's, and 90's, when flying was a fun, and exciting adventure. I enjoyed and had confidence in the abilities of the flight crew, I'll be flying British Airways several more times this summer. Thank you so much for the great experience! Cheryl Olso

Some how I got “offloaded” even though I had my boarding pass Food was horrible Staff were nice and cheerful No headphones were provided

Terrible! I missed my flight to my final destination and British airlines and American Airlines keep pointing fingers on each other’s. Nobody wants to take responsibility
