Arm rests are too small and too close. No screens, movie selection was very limited and poor. Food is pretty much overpriced cheap convenience store food.

Arm rests are too small and too close. No screens, movie selection was very limited and poor. Food is pretty much overpriced cheap convenience store food.

Crew was good, helpful. Flight ran on time.would have liked to take airtransat home to MTL. But the price back from San Jose Costa Rica was MUCH more expensive than the flight from MTL to San Jose c.r.

The on-board crew were professional and friendly and made the trip feel like we were taken care of well. The gate for the flight departure changed three times...not great but not terrible. Considering it was the day of the New Jalisco Cartel mayhem, we can't really complain.

Onward flight was okay. return from Lisbon was poor as we missed our flight due to a long line at the passport control. Air Transat made no effort to accommodate us even though we were at the passport control 40 minutes prior to the departure.

Thank you for making my first experience very enjoyable. You made it all very pleasant

Great flight great seats will absolutely fly with you again

YUL AIRPORT is the worst. 1 Hr to Get out of the plane, 1 Hr To Cross the Border. 1Hr waiting to be pick up curbside. Trafic is ubeliveble.

Flying to a far away destination is a miracle in itself, so please take these with a grain of salt. The seats are a bit tired, and need a freshen up. The entertainment could be a bit newer, especially with all services available now. The food really is where we need help. But again, flying is a privilege, so all is good.

Seats were very tight especially for first leg of trip.

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.

Kept me waiting for hours with the excuse of aircraft needed to cool down and then cancelled.

Well I had insisted to be put on standby because I knew there was one seat so there should have been another. There was, seat 36AC for both of us, the last row in the plane that does not recline nor does it have any room in the overhead bin because of plane necessities. The bathroom right behind so a line up with people's bums on your arm rests, etc. We were happy to get a flight earlier because of the missed connection, but we saw flight people who were sitting in customer seats and I felt we should have been seated there and they should have been put in the back. Plus the stewardesses were wearing so much perfume, I had to hold my nose because of a severe allergy to perfume.

Air Canada was delayed on the initial flight causing us to be put on another flight that took us to a different airport that did not have our connecting flight. We had to rebook the flight from Tokyo to Bangkok when we arrived after clearing customs. We spent and additional 8 hours because of this. Return flight was also delayed on departure but we were able to make or connecting flight in Tokyo. The business seats need improvement, the seats are a bit hard for such a long flight.

It’s a good airline. Polite service and good communication.

The trip was very smooth; the seat was quite comfortable, and the food was excellent and tasty.

We ran into trouble in Montreal. Exited the plane and Air Canada was excellent getting everyone quickly to their destinations. I give Air Canada a 100%.

I was notified 8 hours before that my flight was cancelled due to mechanical issues and they would let me know when they put me on a new flight. Didn’t hear back for 6 hours and was never notified and had to log into the app to find out I was put on a new flight. First time flying with air Canada and won’t fly with them again.

Air Canada changed this flight from July 6th to July 16th without sending ANY notification. This was not discovered until arrival at the airport. We then had to spend 6 hours on the phone with JustFly to get rebooked on a different airline. No explanation given.

Smooth on time flight with standard AC service. As usual food options awful. Wish airlines could offer better quality food services

No blankets provided, no meal or snack service provided for a 5hr flight. No headphones provided, available for a $4 charge, no Bluetooth connection to entertainment system provided. Terrible airline.

We booked seats next to each other. When we got the boarding passes, they were for different rows. The crew were reluctant to help us, so we ended up sitting separately. 1. What’s the point of reserving by seat number if you’re not going to honor that reservation? 2. Even if it gets messed up between reservation and boarding, how is the crew going to deny us the opportunity to arrange to sit together. There were plenty of people flying alone. It could’ve been easily accommodated. Not very customer-friendly at all.

Seats are absolutely not comfortable and large enough. There’s a limit and you stepped over it. I understand that there’s a business class, however for the price it costs, it’s just plain stupid for a 50 minute flight.

The employees at the gate were not communicating, they preferred to give the upgrade to pilots and not to the elite passengers Every flight I more disappointing, clients shooed be priority instead of other employees even if they are pilots, there was plenty room for pilots in economy

I had bad experiences before now was excellent I am glad they have business class again

Provide free food and drinks on an international flight. Add updated head rests

The incoming plane was late and no information was shared. They even announced we would board in 10 muntes 40 minutes prior to the plane arriving, and the website said until takeoff that we had taken off an hour earlier

Boarding was excessively slow. They do it by groups in a way that it doesn’t make sense. After business class , ppl that need assistance and any other priority group they should have ppl board from the back to the front. First rows 20+. Then 15+. Then 10, etc. having ppl sitting in the back board last makes no sense. The libe backame long as soon as ppl on rows 10 or so where told to board. The line went all the way up the ramp and tunnel for 25 mins.

I receive a service for what I pay, so it is fair.

Business class seats did not lie flat. There was only powdered milk for your coffee....in Business Class!! Food was good.

Our flight from BOS - BOG was delayed 10 hours because they were waiting for a Flight attendant to fly from Miami. They lied and said they would give us food and hotel. That was a straight Lie! It never came! We were in the airport for 13 hours with Two babies. We were on the plane 7 more Hours. When we asked to get diapers from our checked luggage, Jorge in Boston told my wife she should have planned better. Meanwhile, the 10 Avianca Employees Sat there and did nothing for 13 hours. Yes, we planned for 10 hours with the wait and the flight, not 20 hours JORGE! If this was an American company we would have got a refund! But they are not up to American standards. The kicker is they apparently needed the 3rd stewardess to serve the food. Guess what? It was 4AM when they tried to serve the FOOD! Everybody was asleep by then! Ridiculous! Never Again!
