I wish my checked suitcase could have been checked since I arrived an hour before take off .

The staff was so kind and friendly! Boarding was efficient and communication was timely. I would seek out flying with Alaska Airlines in the future.

The cabin crew on this team was particularly kind and excellent.

Check in went pretty well and you didn't lose my bag. After I got a drink from the drink cart they charged me for it, and at the crazy overpriced airport rates. Never had that happen before, is that an american thing? what madness.

In both halves of the trip (going and returning) there were problems. Not exactly Alaska's fault, but still really difficult. Outgoing flight was canceled and rebooked twice due to a total ground stop of all Alaska's flights. This required me to change airports with minimal notice and I almost missed my flight transferring to the other airport (which was roughly an hour and a half away). On the return, the first leg was delayed by an hour, and the second leg was delayed by nearly 3 hours. This was a rough set of flights and the communication about all of these changes was minimal. Crew did their best however, so no fault there. Other thing to remember is there is no food on Alaska flights unless you pre-order. Take that into account when you choose airlines.

My flight was canceled because of an IT outage, and they did not answer the phone for 8 hrs. There was no next flight out, I have missed my wedding because of this.

Liked the crew. Multiple delays. Altered my complete day and plans

Apart from the man snoring very loudly across the aisle from us for about 3.5 of the 5 hour flight it was a great flight. I couldn't get the internet to work and stay working. Texting was intermittent for me.

The plane boarded late and arrived late which wasn't really ideal.

The pretzels have no taste. How about a choice of snacks? The flight itself was fine.

I was seated near a "stinky" person. That's not the fault of Westjet🙁😶‍🌫️

The ceiling leaked water on me. The toilets smelled very bad in the rear cabin

When I purchased the flights I included the luggage, the luggage was not added and got charged the full price anyway. Had to pay for the luggage at check in. Initial flight was delayed, we missed our 9am connection (flew with my wife), then the airline rebooks us to the next flights, putting my wife in at 1.40pm and me at 4pm, what a crazy wait time. We managed to fix it with customer service and they put me in the 1:40pm flight too, but they left my baggage behind in the 4pm flight. When arrived to my destination, of course no luggage. It was delivered to the address thankfully late at night. The experience sucked.

Very good experience. Great cabin crew. Much better than expected

Typical Canadian airline experience. Charger and tray were broken, food was poor quality, and yet you're still paying more than flights with equal to better service than elsewhere globally.

Not enough food option. And not enough advices or information about what we are gonna eat.

my carry-on bag was delayed and I did not receive it until the day of my return at the airport. This delay caused me significant inconvenience, as I did not have access to my personal belongings for the duration of my trip. I had expected to rely on my carry-on items, and being without them negatively impacted my travel experience.

Technology issues at the bag-check counter caused a delay, and we were unable to check out our bags, ultimately missing our flight. They offered no assistance other than telling us to book another flight out of Calgary. We arrived with plenty of time; if there hadn't been an issue with the kiosk and the length of the lines due to the technical issues, we could have made it home.

Worst check in and bag drop off experience. Staff were incredibly rude given that it’s the WestJet system that is faulty.

The staff at the airport and on the plane were wonderful I especially wanna acknowledge the staff who boarded us at the Calgary airport. The women who helped us board at the airport were incredible… they were so kind and sweet…I very happy with WestJet and I am hoping I can fly more often to Canada.

Air Canada cancelled our flight and reschedule it 26 hours later that completely interrupted my family's long waited Japan trip, it wasn't due to natural reason such as weather but under the company's control. On the day we wasted 9 hours of our time from 6am to 3pm, including a few hours in the customer counter waiting for supervisor to handle our rescheduling. When we came to the counter for rebooking help there were at least 4 employees on the counter but we were told they were not trained to handle customer rebooking, we were also told the supervisor could come 10:30 to handle our rebooking, but she showed up more than one hour later, the end result was exactly the same so the few hours we spent waiting for her was completely wasted; We already prepaid hotel and all the tickets for the our stay in Tokyo so all of the cost for the first day is completed wasted; The $80 meal voucher issues was far less than our financial loss due to the financial cancellation, and it was not surprisingly invalid (as Your company screw up everything possible along the flight), the vouchers were supposed to last 72 hours, when we tried to used it at our lounge next day less than 24 hours from its issuing at a designated restaurant, the worker there couldn't scan the vouchers after multiple tries on all 4 vouchers issued, so we had to pay the food from our own money; For the two return flights they were also full of unfortunate events that caused bad experience and further delay and waste of our time, both flights departed late and the last leg had another significant delay of more than half an hour after touchdown, the gate was for some reason not available so we waited more than half an hour, when we got out of plane it was almost one hour later than the supposed arrival time; The gate you arranged is the farthest in Vancouver airport, also was the luggage pickup location in Seattle airport; We also called customer service for rescheduling help and after a long time wait (more than an hour) we got a call back but the CS representative was equally clueless and unhelpful. Other than a fatal crash, your company couldn't do anything right and provided the worst service possible among the tons of flights we have taken in our lives.

Was not sent a link to check in online. Tried to check in online using website. Site didn’t work. Called support line, was told it often didn’t work. Went to counter at airport to check bags and get boarding passes. Had to stand in a lineup. They were unable to tell me how much to pay. Had to take a paper to another counter, took a long time to be told what I owed. I fondly remember the days of checking in online, getting my boarding pass digitally, paying for my luggage on line, scanning my passport at the airport to get my luggage tags, and putting my luggage on the conveyor. Easy peasy. Air Canada has really taken a step back in time, and made what was an easy check in experience to one that seemed unduly long and frustrating.

Really out of Air Canada's control due to long delay because of mechanical issues. While doing their best, disappointed by their assumption that all passengers have smart phones. Should have communicated food voucher availability at gate area. Late arrival cost me an extra $51 because public transit was not available, Otherwise, feel Air Canada did their best dealing with their challenges. Will likely continue using them in the future.

They canceled my flight, I had to rent a car, drive 14 hours. They tell to go on line for a refund, but only offer $24 for a $210 flight and you can’t get hold of anybody by phone and no help from staff at the airport.

I wish to travel with Air Canada for my next trip

They were very attentive, polite, professional and great customer service skills.

Business class was not worth the extra charge. Overpriced for slightly larger seat. Nothing special. Small older plane.

Pros: The airplane was new and had in-flight entertainment (tablet behind seats) with new movies instead of watching on personal devices. Cons: the flight time was changed without informing us. When I booked the flight, the time was 13:30pm (also in the email confirmation). However, when I reached the airport, the time was conveniently changed to 14:55pm. When I asked at the counter, they said the flight always took off at this time. The booking was made by Air Canada, but the flight was operated by United.

The app was great, service was wonderful, everything was quick and easy

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.
