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.

The flight was fine. Long wait at security and for wheelchair. Got to gate about 5 minutes before boarding

Disappointing flight experience! ✈️ A two-hour delay, insufficient food and drinks, terrible cabin crew, and poor service overall. No toothbrushes or toothpaste provided for a long-haul flight — absolutely unacceptable! Compared with Japan Airlines, the difference in service quality is unbelievable. Overall, this experience was simply not good enough.

It was our first time flying wit Air Canada. I found most everything very good, however, our flights leaving and returning were both delayed. And we were met with no place to de-board the plane and had to wait an additional 45 minutes on the plane after arrival. That was very disappointing. Also hefty fees both ways on what would normally be a carry on bag on any other airline.

Traveling from Montreal to SFO, after landing in SFO, there was no announcement about where to claim our luggages. Our gate was in Terminal 1, and went to the luggage claim area in T1, but couldn't find any information on the screen. Eventually, an airport agent told us that our luggages would arrive in Terminal 2 luggage claim area.

Very good, easy to check in, 24 hours to cancel, good prices, nice flight attendants!

Great flights. Only criticism is when landed I. Montreal, wheelchair service has no signage or anyone letting you know where to go , just an older gentleman at the desk looking confused

This is a regional jet. As far as those go it was average. Again poor quality for an expensive seat. Not worth the upgrade

All went really well. Except that I was randomly chosen to be thoroughly checked!!

We were reluctant to travel with Air Canada after reading many bad reviews; however, we were more than satisfied with the experience flying from San Francisco to Montreal and back. Seats were comfortable (although on the return flight we had very little leg room) and the crew was friendly and competent. The entertainment was outstanding, with hundreds of choices, from movies to shows to comedy. Our luggage was delivered in a timely manner (a little slow in San Francisco) and we were sent tracking notices all along the way through the Air Canada app. I wouldn't hesitate to travel with Air Canada again.

The flight departed more than an hour later than expected. The flight itself was good. No other problems.
