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 was cancelled around 45 -1hr minutes before scheduled take off time due to mechanical issues we hadn’t even boarded yet. Had to reroute to Orlando so someone had to drive 2 1/2 to come and get me… the alternative was go through Toronto and get a later flight which didn’t work for my schedule. The flight attendants barely gave anyone a smile…not the same as flying when a client/passenger was important. Very disappointed. By the way I have never ever made a complaint online about any company with feedback…even when I probably should have. The only good experience was the boarding desk associates who were very professional and got me on another flight with my checked bags…very nice team.

Actually as my experience with air Canada from Canada to Newark it was crazy for me because it was a lot of delays which for me it shouldn’t be like that, but I was able to coup with it so that was my experience I hope next time they will do good on that thanks.

Delayed delayed delayed cancelled and all we got was $60 food or beverage Embarrassing I'd say

on time quick service but food so so and seats very small. no leg room. I think passengers should not be bringing so large carry on suitcases and should have free check in. Then boarding and unloading would be faster

It was fine. There were a couple of mechanical delays prior to takeoff but it was overall a quick and pleasant flight.

Mixed experienced. Nice staff. Spacious 787 better than cramped Airbus, though my seat was broken. The bad: Way overpriced ticket and charged for food despite 6 hr flight.

Air Canada business class used to be among the best among North American airlines, however it has gone downhill since the last time I flew with them. They didn't even offer any drinks prior to takeoff despite having over 30 minutes on the ground for boarding and de-icing. Once we got in the air the service was fine, however the food was lukewarm at best and just okay. The warm bread and spring mix salad was very good at least. My main complaint is they were letting economy guests use our washroom. Presumably because the Max 8 only has one in the rear. However as I was sitting in row 1 I constantly had passengers waiting in line for the toilet.

Very smooth flight and the crew members were very welcoming.

After nearly nine years without traveling, my son and I decided to take our first flight, and we chose Air Canada and I’m so glad we did! From start to finish, our experience was nothing short of amazing. The flight itself was smooth, comfortable, and truly enjoyable. The staff were warm, professional, and went above and beyond to make us feel at ease. But what really stood out for me was the luggage tracking feature. Knowing that my bag was scanned onto the same flight I was on gave me such peace of mind. It’s little details like this that make all the difference, especially after not traveling for so long. This trip was incredibly special for us, and Air Canada made it even more memorable. Thank you for such a fantastic experience I wouldn’t hesitate to fly with you again!

The plane was cramped and dirty. Not enough liquid was served to stave off dehydration.

Was late but that airport/storm fault. Flight was full but comfortable. Food quite nice. Unfortunate that I had a rather miserable attendant, others were much friendlier

Changed flight terminals/gates twice. The staff and hospitality was good.

Boarding was efficient. Flight left on time. Wasn’t full so we could spread out a bit. Food was ok.

Used to be my "go to" airline but would be my last choice these days. I think some of the cabin crew believe it would be a great job if it wasn't for the customers.

I love travelling with British airways because everything is supper goog

Not that great. There were no entertainment screens, internet, or any way to track the flight path. The seats were fixed in order not to recline at all. The crew and the staff at the check-in counters were the only nice thing.

Experience was good. Could have been better if we didn’t have to board an hour before the flight to ghana and miss relaxing time in the lounge. That process was very stressful

my flight was canceled and rescheduled for two days later

They oversold and down graded me from Premium economy to coach. 75-pound compensation is insufficient if you chose a particular class. I get dehydrated and severe Charley Horse cramps. I requested a bottle of water, even half even less… but no- “We are only allowed to give water by the glass. Nonsense. Lastly, their planes now have a fixed barrier between seats. So even if your entire row is empty, you are confined to just your space. Lastly, London now requires a transit visa for $30 for US citizens. Never travel through London again

I love British Airlines but I think it’s time for a change.My seat was occupied by very large passengers sitting next to me,I felt very uncomfortable and very bad.I’m sorry but I have to say it.
