Needed more leg room. Leg rest and entertainment system box took up a lot of space and I'm not tall. Breakfast was good. Poor quality of the entertainment options.

Needed more leg room. Leg rest and entertainment system box took up a lot of space and I'm not tall. Breakfast was good. Poor quality of the entertainment options.

Great service. Food could be improved but overall a very good airline

All good, except entertainment system could have been better. More choices.

Aircon set too high so VERY warm and VERY uncomfortable.

Great! Flight was delayed by 30 mins but all was great. Thanks.

Arriving at Coolangatta, rows 20 forward, took the airbridge across to the terminal. It was suggested to those from rows 21 back, that we take the rear stairs and to be careful crossing the tarmac. That was all well and good. However, when we got across to the terminal we then had to climb three large flights of stairs to meet up with those coming across the airbridge. No elevator! There were people carrying babies and elderly carrying hand luggage that needed assistance from others.. There was no option to turn back.

Flew premium economy, well worth the extra. Much better seat size & space. Meals & snacks were lovely. Crew really pleasant. Internet is not great, not really useful for anything. Couldn't even send messages.

Overall, a great experience from food and crew. The only setback was that this was the Second flight from Air New Zealand within a week that was an hour late for boarding.

The air New Zealand employees who assisted us with wheelchair aid on Auckland made our transfer from flight to the next seamless. Also were amazing in helping with our luggage and customs in Brisbane.

All was good, the only thing was it didn't run on time.

Delta was great because the flight was almost 5 hours so I had access to tons of movies news, etc. so it helped past the time by no other plane WestJet did not have movies so Delta was the best

I am ina wheelchair and the gate agent knew exactly what to do when boarding just the the one of the flight attendants

This was a West Jet leg and was basically on time. Everybody was helpful and kind.

20 year old 737 but really poor service from the flight attendants who must have been new.

Round trip flight to Canada and back to the US was smooth and efficient.

Bathrooms dirty sinks clogged. No one seemed to clean them. Plane very old

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 wasn't really their fault it was the horrible winds and we just got unlucky.

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

I wish I knew in advance that the connecting flight was by indigo air

I appreciated the vailability of wheelchair services for persons with mobility issues all the way up to the aircraft. What could be better would be the food choices.

Crew and food was good, ok leg room if you don’t have a big box under the seat. And the seats are so narrow (I’m only 70kg), will consider an alternate airline next time

Awesome hospitality, awesome staff, awesome food & awesome travel time. Thanks

Boarding from DOH to SYD the Business Class were pointed in a separate gate but no one there to receive us. Otherwise it was ok.

The flight was delayed and one member of the crew was a bit rude. But apart from that all good.

My baggage is lost. Flight cancelled, Rebooked ticket through long routes. Mental stress, emotional hurt

Boarding delayed, no communication. I left the lounge, and heard a final call, boarding started after a 30 minutes.

Nothing I knew what I was getting into ; no complaints when on string budget

Very tight seating. Crew seemed too dis interested and too slow to remove main meal trays.

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.

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.

Bad, we had 3h delay without clear understanding, which lead to missing my connection flight.

Liked that it wasnt a full flight but we were asked to check carry on luggage as we were told the flight was full so i did, and that was not true. There was tons of empty overhead bins. No entertainment, and only one drinks and snack service when my ladt flight on aircanada in February, Montréal to Victoria had 2 drink service offers in the 5 and a half hour flight. Why only one this time? It felt very "budget" and cheap

Connection was easy to find and quick. Plane was older but comfortable. The food contained beans again so a similar problem of being in a tin can in the sky after eating beans. Overall flight was uneventful which is great.

Enjoyed the A330 comfort, and the inseat entertainment. Horrible disembarking experience. No gate when we landed to sat on tarmac for 40 minutes, and missed my train.

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 really enjoyed the delicious food and the delicious breakfast; I also liked the seat—it was very comfortable—and the service was absolutely wonderful. The trip was smooth.

The food was awful. It had more than 2 hours delay. It was too expensive
