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

Over the wing seat at emergency exit only downside people using lavatory have no respect and wait in the space

Flight delayed any hour and couple of big gate changes

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.

Flight cancelled and Kayak switched our return flight to a red eye. Ridiculous.

Will never book through you again. Very disappointed in the notices and action taken or provided when planes are rescheduled, enough to cause missed connections

Lost my luggage. Filed a report and there is no response. Received a phone call from another airline that said they had the bag and they did not know what to do with it

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

Very Poor Even with the disruptions our flight was delayed twice then eventually cancelled. Subsequently we to this date have lost 3 days of our vacation. The situation still remains unresolved

Flight was delayed 24 hours, then delayed again first was mechanical and second was weather.

My flight was cancelled and I was left to figure out where to find a hotel, something to eat and how to get a new flight at 11:30pm. Wasted a day. Thanks, Air Canada!

Very nice Crew! Not much entertainment, but it was only a short flight, so it is okay for this flight.

flight was delayed 6 hours for weather, then cancelled because of the crash in toronto, but none of the links to cancel or rebook my flights are working

Air Canada cancelled my flight without issuing a refund. I could not make this flight. Air Canada does not accept phone calls Aircanada.com is down.

Air Canada cancelled my flight and did not issue a refund. Air Canada does not accept phone calls to their customer service line 888.247.2262 for rebooking. Aircanada.com is down.

Efficient board despite a 100% sold out flight. It’s crowded on the plane but crew was working hard to get us off the ground on time and served dinner and breakfast. Food was good.

They kept changing the gate (6 times in 30 minutes) and then left us on the plane for 4 hours before departure. Likely was the storm, which is understandable, but the lack of communication and the e constant running between gates at opposite ends of the airport really threw me and my friend for a loop.

Terrible. My brother broke his leg and couldn’t board the flight and air Canada couldn’t do anything about rescheduling his flight. Poor customer service and help all around

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.

There was more leg room than on the overseas flight, which was nice. Boarding was very well organized and the flight very comfortable.

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.

Great crew dealing with the most unprepared family with a million kids and zero sense.

Easy 1 hour flight and right over the Alps, pretty cool!!

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.

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

Food options in Economy class can be improved. The headphones on the entertainment system only have a single earphone active, this can be improved.

Lost my luggage and still not found to this point.

Flight was great (only a short hop from London to Dublin). Wi-Fi available on board(around 2 euros), power sockets, complimentary water and biscuit. Landin/ takeoff all went without a flaw.

I was charged fees for check in bags at the airport by British Airways. It was supposed to be no charge but Kayak messed up my booking apparently and I had to pay for check in bags. I paid $175.

Good crew and on time but old plane and poor breakfast

The worst travel experience of my life. Boarding chaos, delays and disorganisation at every stage. The worst of many was sitting in freezing temperatures for 10 hours whilst asking all cabin crew to turn the heat up to no avail.

They took my carry on and checked it in. Staff in general at Heathrow are not friendly or helpful

There was no legroom whatsoever to the point where my wife dropped her phone and was unable to retrieve it as she couldn’t move. The sound system for the entertainment had a broken socket so was effectively out of action as it just crackled. Just dreadful, I will actively avoid BA in the future

Gate closed way too early - over 1 hour before departure. Put onto next flight. Ticket had been changed without notifying us.

British Airways provided prompt service and maintained excellent cleanliness throughout the flight. However, the business class seats felt tight, and the cabin temperature was uncomfortably warm, making it difficult to sleep. Since I couldn’t rest, I turned to the in-flight entertainment, but the selection was heavily focused on Paramount content, which isn’t my preference. I also found the Bollywood movie options quite limited compared to other airlines. On the positive side, the spirits selection was impressive, and the staff was exceptionally friendly and attentive.

I like Cityflyer as a semi-stand alone part of BA but I dislike mainstream BA thoroughly. A budget airline with budget service but with normal flag carrier prices.

I liked having access to all the Harry Potter movies and the food was good. The staff was also excellent. The pillows and blankets could’ve been better as mine had stains when I arrived
