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.

I did the online check-in as soon as it opened, including all the required info. When I got to the airport to drop off the luggage, Air Canada system wasn't finding my PR card info, which took a long time to resolve. Every time I fly with Air Canada, there is always some technical glitch.

The AC check-in counter closed early and caused us to miss our flight. Our connecting flight arrived late, at 1300, so we picked up our bags and ran to the AC check-in counter, only to find it closed already, although our flight to Montreal was at 1435. We had already checked in online, so the AC staff knew we were coming.

Great overall. Quick boarding, attentive staff - great experience in premium class.

Everything was OK, except one moment. After online check-in, Air Canada have sent me two same boarding passes. I asked to resend, but it comes the same again.

Ground personnel in better mood. Sounded agressive wrt carry on bagage sizing.

We are extremely impressed with all aspects of flying with Air Canada.

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

It was just ok, after a weather delay and had to take 3 planes in one day I asked for another cookie and she said no only one per passenger, found that a bit pity after spending my whole day in airports and planes

They delayed all our flights and lost our luggage flying to Tokyo, Japan. Worst experience I have had with any airline. DO NOT BOOK.

They did great as being my first time flying with them I will consider flying with them again on my next trip.
