The food is terrible. The staff is wonderful. Comfort is good.

For some reason, I couldn't choose my seat. The airline gave me a seat when I got there. Not happy about that. Otherwise, everything else was great!

Left on time, a bit delayed due to headwinds most of the trip.

I fly Delta all the time, have Platinum Medallion status. But this route seems to have major problems with delays and seems to never leave on time! Have only taken it twice in the last two weeks, and each time it had delays of more than 1 hour... very disappointed!!!!

Good seats in Main cabin, excellent service and excellent landing

My flight was cancelled with no explanation after I had already cleared security. I was given 4 options to rebook, only one being non-stop like I had paid for. I grabbed it. It was 4 plus hours later and then took off even later. Biggest complaint is that I booked early and had an aisle seat. They gave me a "window" seat in front of the exit row, so the seat did not decline. I weigh all of 103 #s and it was tight for me! For what I paid, I feel I was kind of ripped off. I think they should have given me the empty comfort seat for the inconvenience. There was no apology nor any explanation as to why the flight was cancelled. My guess is it benefitted Delta in some way.

Very smooth, on-time, and pleasantly uneventful flight. The team at the gate and on board were professional and genuinely courteous. The pilot kept us well updated throughout, and both takeoff and landing were steady and enjoyable without any drama. Just a good, solid flight. Thank you! 💗

Staff was exceptional! Everyone was kind, professional and friendly making the trip very pleasant. Thank you!

No lunch on a x-country flight scheduled for 10:50 am departure, arrived 5+ hrs later. That requires a black box label before you pay for the tickets. Worst, when I checked in online, it's specifically said that lunch was served on his flight for economy Plus passengers.

We had a lot of really rough weather but that was not Delta's fault. Pilot was amazing.

The Sears in the 800s are not too good perfect Airbus why cant the new 737 fix that

Ot was overall fine. Left on time and had basic snacks. Weather was finicky but that’s not the airlines fault.

Even though we were delayed, we were able to make our connection

Crew and customer service were excellent. This flight also had plenty of leg room and seat mounted screens for entertainment. A very pleasant flight all around!

I was in first class. The outlets at my seat did not work. The plane was shabby and run down. I had prepurchsed a day subscription for internet that was not redeemable. I had to repurchase the internet for my flight and then it didn’t work anyway. Quite disappointed in what was supposed to be the launch of a great vacation.

Flight was good and crew was super polite. However, there were around 5 kids screaming the WHOLE 2 hours. I understand kids have to come but parents need to do something to control their children. They make the experience terrible, especially after finishing 16 hour shifts at the hospital I needed some sleep, which I did not get.

Armrest controller on my seat 35D and nextbooennseat 35E did not work right. Hard to press buttons to recognize and 35D had constantnpressure either upmost down somit was nearly impossible to make selections. .

I flew with my dog and had already purchased my dog’s ticket. Even that morning I had called costumer service to insure that my husband and I had seats together since the website was giving me an error when choosing our seats and the representative mentioned our dog. I showed up early to the airport and when I got to the gate and we started boarding I was help back and told that I was supposed to have a yellow tag and that I should have checked in at the counter for them to give me that tag. I was not aware of this, the representative on the phone did not say anything. Nor did I see it anywhere in the checking process online, so if you travel with a pet and are not checking in luggage, just know that you still have to go to the check in counter when arriving at the airport unless you want to be the last one to board and not have room for your carry on in the overhead bins. Other than that, I had a great experience.

The experience was great, the crew was very polite and hospitable. I will definitely make if my go to airlines.

This flight was perfect. No complaints and only the highest regard for the crew and ground staff and how they executed perfectly. I fly a lot with United and would request predictability and transparency in their operations instead of last minute changes.

A little late at the start but all worked out well.

I liked the humor of the captain and crew on the flight from Flagstaff to Dallas. They were humorous.

After arriving in Dallas, the aircraft taxied for an unusually long time and was unable to park at the gate, which caused a significant delay and made me miss my connecting flight. I then had to wait in a very long line to be rebooked, and I was told that no hotel or meal accommodations would be provided. What is even more unacceptable is that my luggage was mishandled and has still not been located. My suitcase contains important medications that I urgently need, and I have been unable to access them due to the airline’s mishandling. This situation has caused me considerable stress and inconvenience, and I need this issue to be resolved immediately.

I appreciated that it was on time, safe and professional. I didn’t like that I wasn’t in a place where I had a window at my window seat. It would have been nice to know that in advance. If it was mentioned in the ticketing, I didn’t notice it.

The inflight staff is never the issue always the extra and charges american charges! Literally 30 bucks for WiFi! Is insane and then it’s choppy and slow. If you pay for it once you don’t need to pay again for switching aircraft especially when there is flight delays

flight was good until we arrived at cmh ten minutes early but then sat on tarmac for twenty minutes because a plane was at our gate, so we had to wait despite the pilot tellling us that 3 other gates were open.

I have a gluten allergy so didn't have any food

Baggage handling poor. Second time this has happened. My bag went to San Francisco instead of Fiji. No apology. Luckily Nadi airport staff are fantastic. My bag arrived in Fiji the next day.

Wish a flight with more than 2 hours with some snack rather than just cookie/biscuit.

Flight delayed and missed connection. Rescheduled flight cancelled after 6 hrs wait. Rerouted thru ORD, flight cancelled, overnight stay in ORD. Still in the air on new flight!

It was disappointing to see the huge number of people who were allowed to board who were claiming to either be disabled or needed extra time to board who practically ran to the gate as soon as boarding opened. One of the female flight attendants in the premium economy section refused to let a lady with an infant use the toilet next to row 9 to change her baby even though the path back to the rear toilets was blocked by staff and trolleys and said she would have to carry the baby to the toilet during the descent phase when turbulence was present. The passenger refused and the baby had to wait until landing. It would have been no problem to allow this infringement of weathers petty rules. The flight was also very cold due to a cold draft throughout the flight from the bulkhead ceiling which was not controllable.

Food good . No entertainment. Need to use wifi to access your own apps. Eg Amazon Prime, YouTube. They don't tell you unless you ask.

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.

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.

Like- beer/wine for free Dis-like- all other aspects- customer service was horrible the entire trip. No help from Air Canada after they changed flight 6+ hours later. Also they put us on standby for no reason. Then almost 2 hours to get our bags after we arrived back at airport
