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

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...

Our flight was delayed many times throughout the day. The final delay was about 8 hours. I spent time in line to speak to someone at their understaffed desk, and also spent time waiting online and then chatting with a service rep. None of the United employees were any help at all. I desperately wanted to go get rest and possibly re-book my trip but I was denied any compensation or voucher for a hotel. I was repeatedly told it was not United's fault and therefore they had no compensation to offer. Overall, a cold and callous experience.

Flight crew and pilots did great. Flight way delayed due to a part needing replacement. Based on what the pilot indicated- the maintenance crew could’ve resolved this more efficiently than replacing whole part- and taken less time

The most cramped seating I’ve ever experienced, (including budget airlines) with no food available for purchase on a nearly 6 hour flight.

Flight was canceled do to mechanical failure I lost my connection flight at to pay $2500.00 more to get 4 more tickets to fly to Ketchikan Alaska This was the worst experience I had flying. I thinks kayak should pay for my new ticket from Seattle to Ketchikan That may bring less pain from my trip Thanks Ilir
