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.

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

I like the crew members they're very friendly. Clean plane. The flight was on time. I dont like the comfort my car seat its better that the plane seats. They charge for everything. This airline was very good. Now it's a low cost airline

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

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

There isn't much space in-between seats and even water needs to be paid for during the flight.

Definitely my worst experience. We booked a flight JFK - Cartagena with a layover at Bogota. My partner and I were on time for the boarding at 10:55pm. We were about to enter in the plane, literally, when one of the officer from the airline Avianca, took the passport of my partner to apparently « looked at his luggage reservation ». It made no sense, first the luggage was under my name, and then we went through all the controls at the airport. The person went back to the gate inside the airport, I followed my partner. The employees from the airline were rude and disrespectful. They were not explaining us what’s was going on. After 5 minutes of silence treatment. They told us that my partner was intoxicated (it was absolutely not true, they never conducted tests btw) and he couldn’t board in the plane and he will take the next one. They didn’t late us coordinated the trip, and not even let us say goodbye to each other. I was forced to take the plane to bogota and my partner to stay in NYC. It was traumatic. My partner had to wait 6h in the airport (night time) and he had to pay an additional ticket even tho the employees mentioned he was going to take the next flight. We are going to file a complain. It’s unbelievable. First and last time I will ever use this airline. I do not recommend.

No complimentary food and beverage (water, soda, coffe) is offered for a six and a half hours long international flight, not even in premium economy, just to try to squeeze a few more dollars out of the passengers. Same happened in the connecting flight, which was three and a half hours long (Bogota x Miami). First and last time flying with Avianca.
