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.

They cancelled my flight and downgraded me to economy and only gave me $250 for the downgrade

Bathroom ran out of TP and floor was wet. Crew seemed a bit unhappy, overnight flights may be harder.

Very helpful ground crew after an earlier flight delay and being rebooked on a different flight.

Not very good , the stewardess were unfriendly and they don't like to be bothered. Cos was a night flight and they need to sleep.

The plane was late and then sat on the runway for almost 45 minutes before taking off.

Fine. On time, cabin service was fine, bag arrived. All good. Flying into DCA so did not collide with any helicopters, which is also good. Horrid incident that could have and should have been prevented.

late again! but its my only option to not take 9 hours to get to Memphis

Flight delayed, missed connection, had to stay overnight. Next flight instead of our business class we were booked on the very back row. Second time this had happened in 2 months.

The service and food needs to improve to catch up with other international flights

Charlotte NC agents were great and ended up with decent seats after having to switch flights amidst Hurricane situation. CMH was a different story. Doors to flight closed 15 minutes before departure so we nearly were left behind. Flight crew were OK but nothing to brag about for sure

Air Canada never runs on time. You’re lucky if your flight is not cancelled or diverted. Worst airline in the world for gas lighting its customers.

There was no food other than pretzels or a single cookie for a 4.5 hour flight. The in-flight entertainment system was not available on the back of the seat - instead I had to use my cell phone and the plane's wifi - which drained my battery even though my phone was plugged into the seat ahead of me and should have been charging - it did not. Very irritating.

No space in overhead bin, one cookie, 2 oz of juice - is not customer service.

Flight was in business class on an older Lufthansa 747. Business class seats definitely old style. Flight attendants were a little curt but attentive. Movie choices did not include anything that would be considered new releases.

This flight was canceled at the last moment and I was stranded in the Vancouver International. I spent the night there without compensation and the staff looked annoyed and wanted to get rid of the passengers without offering much help.

My luggage passed security but just before boarding the plane I watched as my luggage was thrown on the belt to enter the plane in Windsor and my luggage cover was half off. it was damaged before even making it onto the plane! I’ve had the luggage and covered for a year and have never had any issues. I mentioned it to an Air Canada employee who told me to use the app to make the crew aware of this (she said so they could fix it) but sure enough my luggage was damaged with no cover in sight! I sent an email to AC that was ignored. Awful experience! Also, a 4.5 hour flight and you are offered pretzels or a cheap single cookie?? Wow. The return flight did not have any entertainment available unless you used your own device and their wifi. The USB plug on the back of the seat did not charge my phone so my battery drained by using it for a short period of time. There was no warning that this was the case prior to boarding the aircraft. Lastly, the plane was freezing. I asked if they had any small blankets (which used to be standard) and was told they were only for the front section. Would never fly AC again!

On the flight from Montreal to Calgary the flight attendant we had was excellent. Unfortunately I did not get her name but she made the flight very comfortable and enjoyable.

Food hope it make it international not mainly like pilipino food

Just a little improvement on food but everything is excellent

Like- beer/wine for free Dis-like- all other aspects- customer service was horrible the entire trip. No help from Air Canada after they changed flight 6+ hours later. Also they put us on standby for no reason. Then almost 2 hours to get our bags after we arrived back at airport

Food was edible, not great, and served by attendants who looked like they really were not happy working the flight. The section I was in was too warm making the 11 hour flight uncomfortable. Other areas on the plane were fine.

I’ve never had worse food in business class ever!

Checked bG chstgr was extremely high. Over $120. It was s bsit and switch knowing an international passenger would have t9 check a bag.

First, communication was terrible. The gate on our ticket was not what was reflected on the airport screens and TAP personnel were not present at either gate to answer questions. The flight was delayed and there was no announcement. Also, there was an equipment swap to a smaller airframe which affected our level of comfort. The root of all these issues was as a lack of communication. With air travel in foreign countries already being a stressful affair, lack of communication needlessly raises the level of difficulty.

Checkin was very slow, we had checked in online and hoping we could do a bag drop at the airport. However everyone with checked bags had to queue up and it took over 40mins. Our advice arrive extra early or you will be rushing to the gate.

On time, politeness, food okay but entertneiment mediocre with only old movie and the so called new we’re 2 or 3…

Do you have a bad service And And treat customers terrible

Awful. I told them to cancel my return flight and they didn’t then charged me +$800 days before the flight for a biz class upgrade bid. When I called to confirm cancellation and get refund on buz class upgrade they said I had to go thru orbitz and it was too late. Scammers. Beware.

Little leg room in business. I am tall and could use more.

Was a cheap flight and it got me to Portugal on time. For economy there was ample leg room and the flight attendants were pleasant and helpful.
