The flight was delayed by a hour and I wish they had communicated it sooner. No issues on the plane, it did take a while for food to come.

The flight was delayed by a hour and I wish they had communicated it sooner. No issues on the plane, it did take a while for food to come.

Smooth and easy boarding, comfortable for the entire 5 hour flight, and the seat back entertainment was great! I appreciated all the features, from location info and maps, movies, the ability to connect with Bluetooth headphones, and good selection of movies. Food was good, normal airline snacks (I didn’t purchase anything)

it was so bad. I tried to board my flight from vancouver to saskatoon. And to my surprise they did not board me cause the flight was changed and no email was send to me. and on my boarding pass which i got from seattle says different flight. I did not knew anyone from Vancouver, air canada crew was rude, i asked for today flight but they were rude and i had early morning dental appointment in saskatoon. I was so much in pain and my whole day is wasted today. and i suffered alot. They did provide me hotel but they did not provide me any food. I am really really disappointed first time had so bad experience with air canada. I may think twice to book it again. If i can get any reply or any composition that would be great. Thanks

leg space better than expected. two washrooms for one plane isn't enough.

The seats on this flight were almost roomy enough to be the basic amount needed for human existence. I think my favorite part of this flight was it landed at an A gate, which was the most palatial part of Sea-Tac I've ever seen - a massive improvement from the S gates.

Everything was fantastic. Modern plane. All the amenities! Although the paid snacks and meals are pure robbery. Like i understand airlines need to make money, but 11$ USD for an overnight oats with some nuts in it and barely any pieces of apple.... Highway robbery

Never happened, because of the first delayed flight I lost the connection and had to wait overnight and take two flights to reach my destination.

The flight was delayed, but other than that everything was fine.

An hour and a half late is UNACCEPTABLE. The negative impact to our family is unconscionable. And for the price we were forced to pay...

My flight was 3 hours late, which caused me to miss my connection in Denver. Further, this connecting flight was then Later canceled. This required me to stay another night an hour and a half away, and rent the rental car for an additional Night. I am still waiting for United Airlines to reimburse me for the inconvenience and Expense of having to extend my rental Car for An additional Day. See attached receipt. https://share.icloud.com/photos/0f5ns2AaeIr7w6t_uH1qfPBUg
