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.

The flight and crew were good. Departure and arrival were timely. Check-in was professional and helpful in Malaga on return trip (same on outbound trip from Toronto). The ad before ach program was punishing - specifically for the internet/data service with the content creator that was showed twice in each ad pod. It was so annoying I made an effort to forget the name and would not use the service. Provide an opportunity to fast forward or skip the darn ads once they have been initially viewed.

Extra attention to kids, thank you, we appreciate! Perfect landing

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.

Airbus plane, nice and polite staff, entertainment even as it was a short flight.

Very nice and clean plane. Transit time between flights was tight though

Our flights got changed from United to Air Canada and our purchased seats did not get transferred so we had to pay for seats twice. I brought it up with Air Canada and they stated I had to go back and chase it with United. The united seats were $21 Canadian each and Air Canada were $56 each so we have paid $77 for each seat. Very unhappy

So far so good but food and entertainment are not available for this flight

Plane temperature was comfortable (not to hot) when boarding and waiting for takeoff.

Michael, our FA was very attentive, even finding me a chocolate brownie from economy class when the dessert selections were all dairy based. ( intolerant, not allergic so don’t usually need to order dairy free)

We tried to upgrade to economy premium but were told this was not possible as we had booked through United Airlines (and Air Canada was operating the flight). This seemed silly given there was ample space in economy premium. Additionally, we had to wait almost 1.5 hours upon arrival to taxi to the gate. Otherwise, the crew were very pleasant and passengers were friendly.

It was my first time with United Airlines and I would say it was very good experience and best of all the flights were on time. Will definitely fly with United Airlines next time.

headphone jack didnt work for the first flight and not much variety

Plane 3 hours late. Missed connection. No help from gate staff. App horrible. Lost connection repeatedly. No service desk. Finally got help from young girl driving cart.

Not the greatest experience everything was pretty mediocre. My seat was by the washroom in the aisle and was not located well as everyone past each other people were right in my seat and space.

The small prop plane was crowded and the overhead luggage storage is a smaller than on the jets. Other than that, the crew was good, the flight was on time and the landing was smooth.

There was a medical emergency that the crew handled very well. There was no “entertainment” of any sort-no movie/music/whatever. Food was typical of airlines: mediocre.

Late departure, so I missed connection in Detroit. But Delta gave me a great hotel & breakfast. Just sorry I could not get anything from my checked baggage.

Crew was friendly. Lost our luggage and told us it’d be in later in the evening of the day we returned. It was not. Still after 5 days have not received it.

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

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.

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

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

Just a little improvement on food but everything is excellent

Somebody either kayak or Air Canada booked my flight under my preferred name Betty instead of my legal name and I almost was denied boarding my flight

The ground staff was so rude in Toronto airport ...very rude and did not answer simple questions, and made me look like a fool. Very rude ground staff.

My flight got delayed 5 times and then got cancelled eventually, I had to get a hotel and uber and pay for food for an extra night without any plans. It was a horrible experience, instead of Air Canada, I was flying with United .

I had a nice flight with free wifi. So I was able to message family members and stream music during my flight, which made the trip go by fast. I also enjoyed flying on there Airbus A220. The plane looked very new and it also got up to speed fast down the runway and didn't need much runway to get airborne.

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.

Poor planning meant the plane was delayed an hour, then a thunder storm started and the ground staff couldn't work. Eventual arrival in Santiago was 3 hours late resulting in missed connections and the need to buy new tickets.

Ensure prepaid food arrangements are appropriately understood by flight crew of who purchased and who did not

All was fine. Weather was a bit stormy, but nothing kayak can do about that! 😊
