I love the 2 seats per row. More room. The crew were excellent.

It was amazing although they did bump us up to the front which gave us more leg room and a meal. The service was great! The staff were friendly. :)

Overall very good... staff were friendly and helpful. boarding was good for the most part, but a little hard to get our carry-on bags on there.... I think people should be directed to keep their coats and small bags with them until all the carry-ons are loaded, and then, if there is space, they can put their small bags and coats up top.. makes it much easier to put baggage up. i loved the internet feature, but the entertainment was not there unless you have your own Netflix or similar platform. My chair did not recline, which was very annoying, and the arms won't go up near the isle, which makes it tough to get in and out of the seat.

Staff were excellant. Only snacks served. Some turbulence so we were offered Free beer or wine.

The staff is always great. Just the fact that our flight was the only one delayed from Halifax when all other carries were still flying. It happen a year ago out of Toronto as well. All others were flying but our flight got cancelled 1 hr before the time of departure.

The only issue had when i mentioned about comfort was the man beside me was on the larger side and took about 1/3 of my seat where i was pressed against the wall/window of the plane for the trip.

The check-in staff, boarding staff, and flight crew were all very friendly. Really miss the Porter lounge in Ottawa.

Thanks for giving a beer to everyone in the seat infront of me and then telling me that I can’t have one because they are going to land. I guess I need to pay for a seat and then pick one in the very front of the plane

The flight was delayed by more than one hour. The terminal was consequently overcrowded and hot. We lost our car reservation and hit rush hour traffic in Boston, which added two hours stuck in traffic to our trip.

Awesome, the whole way through. Thank you, this is the new Canadian Airline benchmark.

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.

My husband required a wheelchair to get to the airplane and the service he received was exemplary. Thank you.

Internet on both flights was sketchy. Thus in flight entertainment was non- existent on MN - Balrimote leg.

crew was great, wifi was very poor could not even load a youtube video

WestJet was able to re-book us to the next available flight at no charge when air traffic controller staffing shortage delayed our inbound flight

Our flight was delayed for almost 2 hours resulting in a rush to connect to our next flight

I am a tall woman and could not move my legs enough to reach down under the seat in front of me to retrieve anything I put down there. I sat in both aisle and window seats and felt extremely cramped. In the aisle seat, if the stewardess was heavy, it was impossible to pass, and she would knock my arm shoulder and thigh every time she went by. If I can avoid it, I will not be flying this airline again.

We never had an experience they canceled the flight and they did not offer us an alternative flight. I had to book one on my own expense. They offered us food voucher and we could not use them at the airport it kept saying not attached to an existing flight. The people at the counter were rude and cold and they did not care about our situation

It took 30 minutes to check in with the Westjet rep. They didn’t have enough seats and she needed to make a call… I am always “randomly” selected to be checked at security. Their “randomly “ selection system may need some updating. They treat people like criminals. It is not appropriate behavior.

Get our, as a group, skis on time to their destination. Have more attendants checking people in. There was only one. The line was a block long :( . Also flight change with 5-hour delay

Found the seats very crowded—too close together ! And waited a long time for our luggage All staff at both ends were excellent!!!

Lynda was rude and unhelpful. We asked for tea wiht a slice of lemon. She served us Coffee instead. When we spoke to her she made it seem as if we were lying. I asked if she would like to taste it and see - her reply was I don’t need to be rude. After this incident we were treated with subpar service for all beverages and food items after. We’re were purposely left out when they did garbage collection.

They lost my checked in luggage, why do I pay for my cargo not arriving at the same destination as me?

Overall good experience. The flight from Toronto to Denver does not have entertainment - movies to watch.

Not enough electronic outlets for charging in the Air Canada waiting to board area but the Most important thing….the plane was booked to only 40% capacity and my row of 2 other seats were empty. My row happened to be one of the few rows that did NOT have raising arm rests. The flight attendant made effort to seat me in a different row. I needed wheelchair assistance due to a cyst on my knee and struggled to move from seat to seat to get to the row. Those 2 empty seats tormented me the entire 15+ hour flight as I had to be upright the entire flight and was not able to elevate my knee. Lots of other passengers were laying down due to the arm rest being able to retract. It is a shame that he couldn’t be gracious and find a row that I could move to.

Crew was pleasant and efficient. The speaker system for instructions was hard to understand

There is not enough space between two chairs and raws.

Just kinda of a bus ride … we could do better. Delay in the flight :(

My experience was poor with customer Services. Please consider flexibility with cancellation due to emergency health condition. Thank you.

During the pre-departure safety briefing, the flight attendants rushed through the mandatory safety announcements in both official languages, making it difficult for passengers to clearly understand the instructions. Given the importance of these messages for passenger safety, this lack of clarity was concerning. Perhaps use a recoded message to alleviate this concern. Additionally, the flight attendants appeared to lack the professional attentiveness typically expected during a flight. Rather than focusing on timely and courteous service, they seemed more engaged in personal conversations than in addressing the needs of passengers. I hope this feedback is taken constructively and helps in maintaining the high standards of professionalism and care that travelers expect from a national carrier: AC.

Terrible. 3 missed flights and 24 hours delayed with lost bag and promised $100 compensation from United and absolutely nothing from them…

Plane and seats ok. Dinners going and coming back were not fantastic. Breakfast from Seattle to London fine with bagel, cheese and fried egg. Second meal on London to Seattle not my favorite of kind of pizza sauce in a pastry. Came with water about three different times on each of my long flights. Staff on all very friendly and helpful.

I don’t understand why a reputable airline like BA would delegate their London flights to AA. Makes no sense to me, as most domestic carriers do such a poor job these days. Terminal 3 at LHR is a total dump

We ordered kids meals - which were not kid friendly at all! (the breakfast that is - scrambled eggs on a bed of spinach and asparagus?)

Uncomfortable seats. Crazy seat assignments separating families when they could easily have put them together. Good communication from pilot about arrival time after delay in departure. Toilet ran out of water in sink. Snack box poor for flight of this length.

The bed in Club class was not very comfortable, everything else was good.

Cancelled flight minutes before boarding. Rescheduled flight was two days later

The flight attendants were EXTREMELY personable and appreciated the service, lights going off after dinner (probably the norm, but I haven’t flown evening overnight flights in a while). Thank you!

Great room between the seats, food was excellent, very comfortable overall and could have stayed on the plane even longer

I have noticed that the airlines, including this flight, pretend there is going to be turbulence, announce such, and say they can’t do beverage service. There is no turbulence and the seat belt light goes off 10 minutes before they ask for tray tables up and seat belts back on. They are just trying to spend less money and it’s quite transparent

Business class seats were very dated on my plane. Very little storage, charging ports were not easily accessible, tv screen kept flopping away. Vegetarian food was disappointing: hardly any protein and severely under-seasoned. Crew was lovely.
