Crew was nice, meal was good. Entertainment had to be rebooted 3 times and still did not work. Turns out there was residue on screen, it needed to be cleaned to prevent the touchscreen buttons from continuously activating. I had entertainment for the last 45 minutes of a 5 hour 45 minute flight. Really unacceptable for first class. Flight attendent indicated your cleaning solution creates this problem. Seems as if this is widely known, you should be using a different product or cleaning better. Really really disappointing which simply added to the wi fi on your planes with reliably never ever works.

Long flight but comfortable and not freezing as I have experienced on Hawaiian flights to the islands. They gave us blankets just in case. Nice touch.

NEVER MADE THE FLIGHT BECAUSE DELTA SAID THEY CAN NOT

Everything I mentioned earlier - the airbus was more comfortable indeed and the experience was further enhanced.

First class and monitors weren’t working for mine & my husbands. Eventually fixed, but quite annoyed as we bought first class. Also, No foot rests.

It would be nice if was given wires ear buds. Overall was a good experience was able to sleep on the plane

Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.

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.

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

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The plane used to go to Chicago was a bit outdated and needed a refresh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.

Service was okay except attendant over served alcohol to passenger and passenger got tipsy and made me uncomfortable

The window seat on the emergency row was too small. I had a different seat booked and they moved me. My seat remained open. It was very uncomfortable.

Please make more option. And be more precise on the type of food you giving. Diner and breakfast can be different

Flight delayed 3 hours, missed my connection in Atlanta. Instead of getting to Savannah at 6PM arrived after 10:00PM Middle seat, couldn't get isle or window, couldn't book my seats in advance, had to book at the gate. That's a 1st for me and I used to travel a lot

Agent checking me in was great. Plane was nice. Problem was with the handling of my fragile check in. They damaged my steel drum, waiting to hear back from them to see if they will take any responsibility. Think twice about travelling with something fragile, they don't seem to treat it any different than normal luggage

All was good except that the option to purchase wifi for texting throughout the flight didn't work. My partner and I both tried via the app, Chrome and Safari, we tried all payment options. Nothing worked. He was able to get ok blonde with he full coverage option, but it's nice to what we wanted or needed.

Don’t actually know how this flight would have been since we missed it.

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.

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

My original flight was canceled the day before due to mechanical issues. I had to rebook and spend $129 for a night at the airport Comfort Inn.

Delayed 2 and a half hours Middle seat next to a majorly overweight guy who took up most of my seat

Multiple delays and gate changes resulting in arrival with a 5 hour delay.

The flight was smooth, the plane was spacious and clean, the staff was kind and the food was decent.

Pretzels were a bit dry and dusty, however it is nice to have a choice between sweet and savory snacks.

Flight crew was great, and even the crew for checking bags! I had a question for a friend of mine flying tomorrow and the man I talked to was awesome and answered my questions and looked up things for me when he didn’t have to! I was able to give her current & accurate info for her flight and she was so appreciative too!!

Another good flight experience with Air Canada. The business section did not feature the full length sleeping arrangement, but this was a shorter trip. The food was excellent. But the flight crew was truly top tier: friendly, cheerful, helpful at all the right times. Air Canada truly outshines all U.S. carriers.

After 3 hours of delays, they ended up cancelling my flight. And although I could purchase one-way tickets to get to my destination, they would not offer me these flights as compensation for the cancelled flight, and I didn't end up making it home until 13 hours after I was originally supposed to arrive. It made for an extremely strenuous end to an otherwise good trip.

Be careful about the bad policy and when purchasing seats

Very disappointed with premier lounge. Food selection very poor, both coffee machines out of order. For the price you charge for an upgrade, the seats don’t fully recline, movie selection is old. Not very good value. Asian airlines are light years ahead at a more affordable price.
