I have only flown Air Canada and British Airways, and while both are excellent, I have to give the edge to British Airways.

Pack food for yourself before boarding Air Transat. Blankets, pillows and headphones are not given for free.

Airline reviews

The pilot came out and chatted with the passengers. He explained why there was a slight delay. The crew was excellent. Very helpful. I had to buy meals for my whole family and they were in different seats, so the crew had to deal with that. They were very pleasant and accommodating and did a great job!

We were unable to land in Liberia. It was not the airline’s fault, but we had to be diverted to SJO.

We had things stolen from our luggage, we also were refused an upgrade on a flight that was not full.

When we left, it wasn't Great . People were drinking heavily, very disrespectful Extremely loud, the entire trip. I think the crew members, should have get their attention. Coming back was great.

I sat in the club. The seeds were fantastic. The meal was great and Entertainment was good. The crew was fantastic. I recommend it to everybody.

The food was small portions and not fresh. I was seated at the back of the plane so by the time the cart approached me most of the food options were sold out. The cabin crew was fantastic however.

Great flight and crew. Food isn't free and neither are headphones...

We were in economy class but paid for option Plus which offer you an extra snack after take off, free earplugs & blanket. The crew were very attentive. The comfort however wasn’t great, hard to be comfortable in such restraint place. Wasn’t able to sleep through out the 7hrs flight and was exhausted upon arrival.

The flights were on time and the crew was friendly and helpful. The food was ok. The seats were quite cramped and if the seat in front was tipped back there was very very little room. The entertainment was only on your own device and there was no usb charging

Boarding and staff were excellent. The food was ok. Very cramped seating. No existent entertainment other than on iPhone over wifi with poor choices of movie or shows. Bring your own entertainment. Nowhere to charge your phone

They delayed flight because lack of staff then missed connection. Never flying with kayak or weather

Very good over all , would have been nice to have entertainment on the flight

Experience was good. Was surprised they didn’t offer a complimentary meal on a 5 hour flight.

Too squished in seats. I'm 110 lbs and 5'6....can't imagine being any bigger and flying

The flight attendants were great, but not much room while sitting and it would be nice to get free movies.

Absolutely the worst airline I have ever taken. They lost my baggage and told me my bag tags had been cancelled. When my bags arrived days later I had to pick them up at 3:15 am. My return flight was delayed another 6 hours and they broke my bag. Westjet does nothing to try and make it a better customer experience and all the customers services representatives I spoke with were useless and incompetent. Never flying westjet again.

Easy self checkin and baggage drop. No in seat entertainment, but wifi and app worked well

it's all good nothing you can do make better 😌

Flight was delayed due to mechanical issues to the point that I missed my connection and had to wait for 6 hrs in Calgary... thankfully I wasn't in a rush or that would have been annoying

It was an awesome experience flying with Westjet. This was my first domestic flight experience in Canada.

Delay after delay.......they are awful Delayed because of cold wx really!!!!! We live in Canada

I had to change the gate so many times that I got confused.

My one complaint was that while we boarded using the standard enclosed gangway, when we arrived at SEATAC, the ground crew were slow to hook up the stairs. After reaching the tarmac we had to walk up a long ramp all outside in 35° weather. We just came from Bali and did not have warm weather clothes. This was in addition to having to collect our bags in Vancouver, take them through security again and then having to show our passports 4 more times all within the Air Canada section.

The speaker flight attendant talked over was way too loud. Hurt my ears -had to take out hearing aids.

So we didn't actually go. We were hoping to go for the Inauguration of the first female president. When That Guy got elected, we bailed. Unfortunately, we got basically none of our money back, despite having travel insurance. Would not fly with Air Canada again unless I had to.

Did not happen. After being late over and hour we had to embark and get rescheduled . I got my hotel voucher 1:36 am !!!! . The flight was cancelled past 10pm. I had to pay for my hotel and camp the next day till 23:30 for flight to london. Then change airport and pay myself for transportation to Gatwick airport. Never again I will use your services. Unfortunately I have to come back.

My flight was delayed for more than 18 hours no accommodations was provided spent the night at the airport

Economy middle seat was so narrow that I could not sit back comfortably with passengers on either side of me. Over the 9-hour flight, with my body slightly twisted most of that time, my previously-healthy left knee became very painful, even though I got up to walk multiple times. The knee is still painful 3 weeks later. Otherwise, it was a nice flight, but I was crippled over my entire vacation.

flight was delayed, there was open communication about the delay the delay pushed way past the posted delay time and

This was my first time flying on Air Canada and the experience was good and pleasant enough, great crew members and the price I paid was amazing,

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.

Flight was late, with scheduled 50 min layover at Frankfurt. Arrived at gate A54, had to get to B5. We now had 35 min layover with delay, at top speed it took 30 min to get to B5 hot and bothered. Not good. Boarding in Lyon was normal chaos, shoving, and total disrespect for anyone beyond group 2. Boarding for Milan flight was more civilized as we all had to take a bus to plane.

The flight crew did a good job, the main problem I had was in the layout of the pod itself. I know it does not matter but the connection for the head phones was not A- easy to find, B- very difficult to do based on the placement ( behind the right shoulder, very hard to reach, the type of plug on the frame vs the actual plug of the headphones), C due to the location and the way it connected, it did not allow me to use my own headphones, D- very low quality and very uncomfortable headphones, E- Surprisingly, very old selections of movies, for me, at least. I will still fly with Lufthansa as you deliver a very good product overall and I enjoy the quality of service, the ease and the prices. Thank you.

Flight was late and I missed my connecting flight to Dublin. This is not the same Lufthansa I remember, you guys don't care anymore. Hopefully my trips with Swiss Air will much better.

my flight was cancelled. next one scheduled 2 days later. no hotel provided. worst airline experience ever

Food selection wasnt great, even for flight meals. However staff was e extremely pleasant

Sun express is great. Frankfurt airport is the most horrible airport there is

Crew had connection details for only 2 other flights and gave less than empathetic guidance.

The crew were professional and friendly. It was the most uncomfortable international flight I've ever flown. Crammed in passengers. No overhead space to put my bag. No leg room and unable to recline seat due to seats too close together so it upset passenger behind me! Upgrade price to get 2 inches of more space unreasonable.

BA have long since lost their way. They are a budget airline without the budget fares. Everything from booking to boarding to flying to arrival is just plain ordinary. I fly BA if the only alternative is Ryanair who are even worse. Otherwise we fly KLM or Lufthansa who are so much better.

An hour to check-in because they were not organizing the counter personnel well; they lost my baggage and after 48 hours they so not pick the phone, answer emails, and I still do not know how to claim my essentials (its purposely not their on their "help" page).

Courteous and warm. Good experience while traveling back with an infant.

Missed food service or not enough food available to serve the passengers. Very poor leg room in economy. Uncomfortable and old seats with some of the seat covers coming off. Lights, entertainment system and call buttons not working for an entire section of the flight between Del-Lhr. Very poor experience overall.

Boarding in Dallas was hell with extremely rude gate agents , especially a lady named Rajathi who was the epitome of rudeness with no compassion at all . She was horrible and I wonder why airlines have people like her on their roster who exude arrogance and haughtiness . Will probably not fly British Airwsys because of people like her .

It was just ok. Half the bathrooms were broke on the flight.

Was very bad the cancel the flight after when we arrived to London

1. Missed to deliver bags at Destination 2. no coordination at Layover for flight connection for wheel chair , could have missed flights 3. Customer service agents are not honest , talk with attitude and do not provide correct information about baggage policy

Denied boarding passes for connecting flight. Missed connection as a result. Customer services T5 Heathrow airport vile, arrogant people who lied to us and threatened us.
