The plane was a rather tired 737-800, with old style small luggage bins. Poor air flow. USB charger in the infotainment system was not functioning. The flight was 2 hours late due to crew rest requirements (not their fault). On arrival in Seattle, waited on the tarmac for 30 minutes with very few updates from the crew.

The plane was a rather tired 737-800, with old style small luggage bins. Poor air flow. USB charger in the infotainment system was not functioning. The flight was 2 hours late due to crew rest requirements (not their fault). On arrival in Seattle, waited on the tarmac for 30 minutes with very few updates from the crew.

One of the restrooms didn’t work. The ones that did never got replenished. Flight attendant just sitting there on their phone. No notification that the bathroom was broken so long lines. Apathetic crew.

I am in a wheelchair The gate agent knew exactly how to boarding A wheelchair first also the flight attendant knew exactly what she was doing

They did everything right and everything happened right on time.

Not really a “Delta” problem but worth mentioning: Boarding was a difficult process. TSA seemed understaffed and Pre-Check took longer than regular TSA. The supervisor was frazzled and yelled at travelers. Once through TSA, we had to put our carry-ons through another x-ray machine. Then queue up to board with both boarding pass and ID. Then, when we got to the stairs on the tarmac, we had to show our boarding pass again. Maybe this is just normal for Kona since the terminal is outdoors (but still a “secured” area).

Checkin was good, fllight ws good. Onlly complaint is lack of foot on 6 hour flight from Seattle to Boston. Snacks were flimsy - chips and cookies. could have offered something more substantial for such a long flight. I know you can buy food in airport but for the price you pay for a ticket, they should step up for the passengers.

Overall it was not that bad! The delay on the second leg to Indianapolis , was really unexpected!!

The flight was oversold and they kept on announcing they were looking for a volunteer to give away their seat, but the announcement has to be louder and clear @ gate 88 and also must precise. Additionally, the departure time kept on changing. But overall it was fine since it was a short flight.

It was a Red-Eye flight so was not comfortable enough to sleep, but seat was as expected. Crew was great and in-flight entertainment was excellent. Flight was smooth

I received the two differed meals: chicken and pasta. I asked and I received. I am anti-wasting food!

Overall, it was good. I was seating next to a wonderful lady and did not notice how time flew. Thanks

Very nice and clean plane. Transit time between flights was tight though

So far so good but food and entertainment are not available for this flight

HORRIBLE WITH THEIR WEBSITE!!! WORST WEBSITE IN THE WHOLE AIRLINE INDUSTRY

There was no room in overhead bin to place our luggage despite we had tree seats. It means a lot of people had more than 1 carry on bags. When I asked a crew member to help she said that it was not her responsibility.

The plane used to go to Chicago was a bit outdated and needed a refresh

The check-in and passport submission was complicated and repetitive, due to the poor communication between Air Canada and United. There should have been a single set of instructions and a single questionnaire that provided the data for both airlines.

It was good! Appreciated that it was very on schedule so it made the connecting flight less stressful

Internet was not working for a bet . Hard to order food with our credit card because it was not in your system .

Booked economy through United - air canada treated it as standby and was almost refused boarding.

The crew were all helpful, kind, and effective. There could have been more space under the seats.

Horrible, delayed 3 hours due to a mechanical issue where the plane is deemed unsafe so we had to deplane after an hour on the tarmac. No credit was given even though plenty of passengers missed their connecting flights and then the baggage claim info showed that no flight was being loaded on the carousel whilst the bags were being dropped, so no one knew if it was the right flight or not since the arrivals screen didn’t show anything.

The agents at the Kelowna YLW airport were really grumpy. Same with oversized baggage person. Staff on the plane were great.

The window seat on the emergency row was too small. I had a different seat booked and they moved me. My seat remained open. It was very uncomfortable.

They lost my bag. Hopefully it will be here tomorrow.

Please make more option. And be more precise on the type of food you giving. Diner and breakfast can be different

Flight delayed 3 hours, missed my connection in Atlanta. Instead of getting to Savannah at 6PM arrived after 10:00PM Middle seat, couldn't get isle or window, couldn't book my seats in advance, had to book at the gate. That's a 1st for me and I used to travel a lot

Lost my luggage. Filed a report and there is no response. Received a phone call from another airline that said they had the bag and they did not know what to do with it

All was good except that the option to purchase wifi for texting throughout the flight didn't work. My partner and I both tried via the app, Chrome and Safari, we tried all payment options. Nothing worked. He was able to get ok blonde with he full coverage option, but it's nice to what we wanted or needed.

Terrible! Delayed three times, landed at some corner of airport, walked in bitter cold night, took a bus, bad experience

Although there were two delays, they were communicated clearly and the boarding process was expedited. The crew was pleasant and efficient.

Plane was super cold. No entertainment unless you were with mileage program Getting off the plane was super slow

Beverage service was not good. Also just one service in 5 hr 30 min flight. No ask fir water ir anything beside one time beverage service.

Flight was delayed because of a bird strike. They had another plane available within 45 minutes.

The flight was on time and crew were nice, seats were tight and there was entertainment available

Worst flight ever. I was suppose to have a 3 1/2 hour layover in Chicago but got to the gate 4 minutes before boarding.

A cookie and a soda, packed like sardines, will never be a positive experience. Also, boarded a 5:30 flight at 7:45pm

It was a code share with Alaska - would have been great if I actually made it on the plane, claimed I didn’t have a ticket or a seat even thought I was checked in.

The main problem was delay. The plane was at the gate early and bags were loaded. However, there was no crew for the flight. They were inbound from LGA and had to land and make their way to our gate. It took more than 40 minutes. Then, once the crew arrived and boarded, one of the crew members had to deplane and then a replacement crew member had to be found. It took another 40 minutes or so to get the final crew member. In all, we took off about 2 hours later than our scheduled departure time. Once in the air, the flight was great. Smooth most of the way. The crew was professional and efficient.

The crew was very helpful and the aircraft was clean. More attentiveness to us in business class.

it was by far the worst business class experience i've had. the food was awful, the staff was worthless and lazy, the drinks were warm, no blankets. dirty bathroom.

I could not even make this flight due to Air Canada delay on my first flight. I had to be booked with American Airlines and arrived 13 1/2 hours late. Terrible customer service.

Flying with Air Canada is not pleasant at all. The plane is very old, meaning that there is no on board entertainment, the leg room is less, and it is dirty and in poor repair. To make matters worse, the crew was pleasant enough on my initial fight, but very rude on the return flight. Furthermore, the website advertises many amenities for international flights that are not honored when you were flying from the US to Canada even if your flight is five hours long. Even if you are willing to purchase food, they will likely not have over half of the advertised options available. In addition, you will pay twice the amount of a child’s order for an adult order of same item even though it is the same size as the children’s. It was just really bad on many levels I will try to avoid flying with Air Canada again at all costs

Terrible! Our flight was cancelled. No other nonstop flights available. Had to rent a car and drive 7 hours!

I wasnt able to choose my seat during booking my flight _months_ in advance and then when I checked in for my flight, I _still_ couldnt choose my seat. I was finally able to get a seat when I got to the gate, and they stuck me in a middle seat next to a jerk. This was my return flight, and on my departing flight I was able to choose my seat, so I dont understand what the issue was but it was very annoying and a miserable ~6.5 hours on the return flight.

Overall, I would have to say my experience with Air Canada was mediocre their DC tens. Need to be updated not comfortable at all. Only one out of my four flights was decent. The staffing was very nice. Going through customs in Montreal was quick and easy. Air Canada has room for improvement with their facilities.

No food provided atl on a 5 hour flight. Took an hour at SeaTac to get our bags

The embarking was in the middle of some part of the airport then we were cramped in one bus many of us and so stuffy since it was so crowded

A quiet, uneventful flight. Crew were polite and helpful. Passengers were informed of reason for any delays. We managed to arrive 30 minutes early. Meals ran out before my row, though snacks and cheese trays were available.

Flight cancelled after long delay, rudely denied compensation, incurred significant expense. Placed claim. 6 weeks later and still no reply from Air Canada.
