Great! Personable crew. I love that they pour complimentary beer and wine.

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.

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.

Flight was delayed but the real issue is how long we sat after boarding. Space very limited for an overnight flight and seatbacks didn’t recline so it was almost impossible to sleep.

The staff made sure I was comfortable, moved me to a better seat with more leg room

Somehow, my booking was under my preferred name instead of my legal name so they almost didn’t let me board the plane at LAX. This problem should have been notified to me when I was still in Toronto.

When arriving over 2 hours early to check k in at Charlotte airport I was told I would have to check my carry on ? Apparently the flight was full and may not be room. I was not given a choice and the agent was quite unpleasant about it. I am a senior amd was not comfortable me having to worry about my bag being lost vut it didn’t seem to bother him. There were lots and lots of people of all ages in line when we boarded with carryons and most larger than mine .the rest of my journey was pleasant vut this was totally unacceptable.

the seats aren't the most comfy -- too little padding and I could feel whatever the passenger behind me was doing. Otherwise, it's all good.

This flight didn't happen for me because of overbooking.

Everything was simple and easy. The lady at the gate was super friendly, I wish I had her name to share. She's a little older, dark-haired. You can tell she likes her job and would be a great influence on any young people training with her.

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.

Service is pretty good. Sandwiches have to be purchased but I’ve bought my own food. Seat was comfortable and various movies to chose from.

The staff could have been friendlier. And Having the flight on time would have been much more convenient.
