Airline reviews

Boarding is very confusing. They have Line 1 and Line 2 and many many Boarding groups. Everyone lines up under those two lines long before they call zones. If you have a higher zone 2 like I did due to a Premium Plus ticket, it’s very awkward having to ask each person which zone they have. Extremely chaotic process. On board the flight attendants had no charisma whatsoever, even to us paying extra for an upgraded cabin. I asked for a chamomile tea after dinner (as no coffee or tea was even offered) and the FÃ said they didn’t have even though listed on the drink menu. Also, the mid flight service was entirely skipped which was a soup and sandwich combo. Supposedly had a variety of snacks mid flight too but those never materialized either. A few times I walked Back there, not a single flight attendant acknowledged me as they were all deep into their iPhones. I simply Wanted a glass of water since ZERO water runs were made on this 9hr 30 min flight.

Plane 3 hours late. Missed connection. No help from gate staff. App horrible. Lost connection repeatedly. No service desk. Finally got help from young girl driving cart.

Fight was delayed an hour due to operational issues ,then further delayed due to ground control for a total of about 1.30 hours. Salad was completely frozen and flatware was so cold you could barely handle it. Crew was friendly and professional and the flight was smooth. The aircraft was clean and well-serviced.

Flight was delayed two hours. No snacks and no tv screens. My bag got stuck in Chicago

Most disapointing experience. We were rerouted to Toronto, after a 7 hours flight , where we sat on the tarmac for a little over 4 hours, in a full airplain with no air. We were given a tiny cup of water twice during that wait. After the long wait we taxi out of toronto to wait another 30 min. Many people missed their conections including my kids and I. We were promised a hotel room in Montreal on the aircraft and at the exit of the aircraft, then directed to a desk after custom where me and my two kids were told that we do not get a room for the night and that we were on our own, after a back and fourth and stating what was told to us, the agent at the counter says that we are right and that we should have a room. I ask the lady if she could look into a different flight for us for the next day as I was with two you g kids and wanted them to get some rest. The gentlemen next to her jumps in and said there wss nothing without even (pretending) looking at their system, I insist and say that they could look for the kids. They seemed to have trouble with our reservation so they gave up. I told them that I needed to talk to a manager, they said there were no managers and that no one can do anything, to which I responded that there must be someone that could do something and that it does not make sense for them to repeat the same think as we are not undestanding each other. She threatns to call security and says I am rude. I say I will go, just give me the vouchers and ger response is “ not giving you the vouchers because you are rude”. I was not rude. It is normal to want to talk to a manager. I even said that the people at the counter were not resoonsible for the long journey and that there was nothing they could have done. But to threten and himiliate someone just because they ask for someone else to talk to ? I understand they are overwhelmed, but you know the quality and calibre of a company in the bad times not the smooth ones. I ended up leaving and paying for my own room and board.

Staff was generally seeming stressed out and was a bit rude and slow. Plane left late. Pilot was very well-spoken.

The first flight was an hour and a half late leaving, thus missing my connection. The second flight Departure was two hours late Leaving.

Waited for our plane from HNL so we didn't miss connection. AMAZING Service for that, then really clean plane. Nice airline attendants.

No access to the Wi-Fi, noisy group of people made it difficult for me to hear through my earbuds. Snacks and drinks - limited service when your seat is at the back of the plane - people up front are always served first and the back gets whatever is left. Not pleased.

The Frankfurt airport is just not that easy to get around. Having to get from one end of the airport to the other when it was not well marked was a challenge. The flight itself was fine. I would fly with United again.

The crew and food were very good. The plane was dirty..

I was happy with the screen in front of me, that for a long time it was just black and not visually distracting. Then I discovered that I could just turn it off if I wanted to. Then I found some simple games and was happy to play those. I was happy with the service too. I do wish I understood the zones though. I wish there was a way for us to board and disembark more efficiently, or at least to board more efficiently, like having all the window seats fill first from the back to the front of the plane and then the other seats? But I do realize that there are perhaps already hundreds of more industry specialized experts & analysts who have been looking at efficiency for decades! I just take the stop & start boarding process with humour and I happily sit to await a simple departure after all those around me have been standing or bending for far too long. You must be used to it, but it still mystifies me why people hurry up and then just stand there.

Was good all around. Crew, food, paid for extra legroom, as 10+ hour flight Like the 787 as I don't have any problem with my ears, due to the planes pressurization.

Had to buy headphones. Which is sad. I did not so I listened to podcasts and slept. Free beer is excellent a d those pretzels are great too. Overall I feel Air Canada slightly exceeds Westjet for overall experience. But still more can be done. Like allowing guests to view a movie for free.

Seats small for international flights, food not good, bathrooms bad, small isles to carry along. For small local flights it’s okay. Emirates had big seats for flight between Dubai to Karachi

Arrived at our connection to find out all 4 of our seats were moved in different parts of the aircraft. Traveling with two small children, this was not going to work. We spoke with the gate attendant and she was not helpful and downright rude. They could only “accommodate” having 2 seats together and this was an international flight. We will not be traveling with air Canada again unless there are absolutely no other options.

Overall the new aircraft’s is good and crew is good. Just overall airline policies and process needs to be better.

Seat change. New seat 5 rows back from our group. Flight ok but we had to wait for half an hour after we landed for the gate.

Air canada always does an excellent job with business class friendly staff great food ......

Ordered the vegetarian meal. Perhaps the worst in flight meal i ever had. Soggy and sad broccoli, overcooked rice and a FROZEN cheap fruit salad.
