Flight was delayed an no one make an announcement about it., they only have Coca Cola and nothing else., the food that was served was cold… very bad experience and service

On my way home I had a layover. The flight from ATL to CLT was amended 5x while I was waiting. I could have driven home sooner. Overall from Dallas, Tx to Charlotte, NC I started my trip at 4:30pm, I didn’t get home until past midnight. I know things happen, but 5x to make me run back and forth in an airport from different terminals is excessive. I also upgraded to comfort + , I didn’t feel it was worth it. There was no benefit

They did a fine job. Can't wait to use Delta in the future.

There was a loud squeaky sound the whole time we were flying.

Had a broken tray in business class. Crew just shrugged it off.

Seat back monitors and outlets were dead and not working.

Everything was great except for the seat. The backrest would not stay in the upright position.

I usually have a positive experience with Delta. Complimentary upgrades are always nice!

Flight delayed about 2 hrs so it made it a VERY late night

I wish that seats closer to the front of the plan were available, but when I booked the flight the seats were VERY expensive so I did not book seats at that time. The day before flying only seats at the back of the plane were available. It takes so long to board the plane and empty the plane on arrival due to SO many roller bags.

Good flight. No I’m seat entertainment. But my phone worked just fine on the west jet app.

I had planned to watch the Westjet entertainment for the entire flight however, because the seat mounted outlets in our row did not work.

Not a bad flight but our priority tagged luggage was the very last to come down the carousel.

Plane had a flat tire, delayed boarding and takeoff but one in the air, smooth. Make sure you have downloaded the WJ app before you leave. When on board, you can watch movies or TV shows offered on the app, it passed the time very quickly.

Our recent flight from edmontown to kahalui was excellent. The service staff was very friendly, knowledgeable, funny and attentive. Thanks to all involved that made or travel such a pleasant experience and we hope to fly with west jet again soon

The flight was delayed and I missed boarding my 7 day cruise. I had to book a separate flight home

No real issues just wasnt able to hear / understand any announcements flight attendant was making but everything else was really good- ended up checking my carry on case for free which made deboarding quicker. I would fly West Jet for all my flights.

Seats were comfortable and leg room was good. Slight delay for boarding but nothing too bad. Would fly with them again.

Long lines to board with only two staff checking boarding passes!

Due to one crew member not showing up to work, our flight was significantly delayed causing us to miss our connecting flight in Houston to Mississippi causing us to be delayed by more than 6 hours and missing our event all together. Very disappointing. All because ONE crew member called in sick. United did grant us a $15 meal voucher, which was a small but appreciated concession that I wasn’t able to use because I ordered my lunch and paid for it before applying the concession, and the staff said it was too late to use it. Ugh! We also had a TWO delay coming back from Mississippi, but that was on American Airlines and it was due to weather, so not their fault. Anyway, not at all impressed with United’s handling of our flight and the HUGE disappointment of missing our important family event for our 90 year old mother. All that money and all that stress and emotions for nothing. Having to wait the hour to bring an employee from LAX seemed like something that should not have happened. Why don’t you have a local back-up? Santa Ana is not a little airport in a rural area.

Terrible. 2 hour delay. Sat on the tarmac. Missed my connecting flight. Had to ARGUE with Customer service to get a hotel and food. Terrible experience with my loyal carrier

I liked the exit row seat. Hated the distance between gates in Houston.

Trip was smooth bumpy from the wind but no issues at all the crew attendant was very pleasant and had great customer service

The customer service was excellent! Check-in, baggage check-in, boarding, the flight went very smooth.

Leg room was lacking. Legs crammed into seat in front.

Awful. I got stuck next to a person carrying a dog and behind someone with a dog. People need to board these dogs downstairs. The cabin is crowded enough with your pets

It was delayed several hours which delayed our connection in Denver. Not happy.

Ok, but comfort was lacking as the seats were way to small

All good except paid for wifi that did not work

Flight was delayed, I had to put my luggage all the way in the back! They served only a beverage no snack on the way in Air Canada, definitely not a good first impression.

When we got to the airport for our flight from Chicago to Montreal which was scheduled for 2.00 p.m. they had no record of it and booked us on a flight at 3.30 very disappointing . We also had to pay 50.00 each for a seat. All things considered ,I will never book thru Kayak again. Next time I will only book directly thru Air Canada no second party booking Sue

My flight has been canceled and I had to cancel entire trip.

No food for a 6 hours flight! Plus very expensive to buy ! Sit uncomfortable! Awful!!!

There was no food on this flight. We had less than 1/3 full plane and were not allowed to spread out. Staff gave the story of the plane had to have all of us up front for 'balance.' Total bs.

There were changes to my flight with many email and very difficult to keep up with details of changes. I consulted Air Canada website that said I was to depart Casablanca at 9:35 but when I got to airport that take off time was delayed by 2 hours. That's 2 hours at an airport instead of bed. I don't understand why Air Canada website didn't show the change in take off like they showed the change in transfer. Do better.

I was delayed from Montreal to Tokyo for 3 hours and they didn't compensate anything

Flying Business on Air Canada is wonderful. With ultimate destination in US, you get the Lounge. Only problem is there was no lounge in YQB so it had to wait until connector in YUL. Flight itself is only about 30 min like the old DC-NYC shuttle so there was no service other than almonds and the bottle of water that was at your seat upon boarding. Would have been nice to be offered a beverage and there was enough time to do a quick pass for the 16 seats. That and having a lounge in YQB are only complaints, but that's very first world complaint. The FA were cordial and professional if not warm. It was a good flight and I'd do it again. But, word to the wise, it's a very different experience doing border check in YUL than YYZ. Long walk and had to go through full screening (including taking off shoes and having to chuck the bottle I had just gotten not knowing there was going to be a frull screening since there was no warning) at YUL even though never left the terminal after landing. YYZ was just a passport check. This is not A/C's fault, but travelers should be advised/warned in advance so they know what to expect especially since you land and have access tot eh terminal and it's stores and food before you get to border check. If you have mobility issues, the distance can easily be a problem and there is no warning of how long it is until you have reached the end. My mom would not be able to navigate it and someone like her may not be able to stop in the middle of an empty long corridor to ask for mobility help. A sign offering how long (10 Min, etc.) the walk is like at new LGA terminals goes a long way. Also can be stressful if you're tight on time for a connection.

I’m 5’3 115 lbs and felt so cramped in this express jet. My carry on actually meets the requirements and still had to be stuffed Into the overhead and barely fit down the aisle. Not a great experience. Air Canada needs to replace these planes.

I liked that the flight was on time for departure and arrival
