the whole trip was smooth, and as comfortable as flying is these days. flight crew was friendly and very courteous and helpful.

Very poor. The flight was delayed from Toronto because some forget to do there job . I got to my connecting gate in San Francisco 10 minutes before the departure.but this didn’t let me board even though the flight was still there for an other 30 minutes. The the gentleman at the unite airline desk told me that they usually wait for passengers but air Canada called and told them not to we I been rerouted to Manila instead of Hong Kong . In San Francisco they mad me check in my carryon bag . I was told the it will directly go yo ho chi minn cuyt but I was told that by the Vietnams airline desk that’s not there I’m 10 hours behind my scheduled flight and looks like I I’m going without baggage. I don’t have a chance of catching ..

First class ticket gets you a choice of chips or nuts. . Just like economy Southwest. Also no screen in the seats. This is first class???!

Flight arrived 30 min early and bag was waiting at the baggage pickup. United Club HNL was one of the nicest in the system

Mean flight attendant. I wanted to reuse my plastic cup, but he (Matthew) said he can't for safety. I then said "I don't want water then" and he poured me a glass. I hope Matthew gets herpes and spends the rest of his life poor, lonely, and homeless.

Yet another flight in which beverage and snack service was skipped. Other that that, firmly mediocre. Landed early, to gate late due to congestion at the gates. Airline's fault or airports fault: unknown.

Both flights delayed. 2nd flight over 3 hours late mechanical issues

It was good but only meal served is very less. Meantime good to add rice and chicken in one of meal

Teeny tiny bathrooms, crew was not realistic about when we'd arrive.

On the way my flight entertainment wouldn’t work the screen went black and no matter how many times I tried to turn it on it wouldn’t. Food was surprisingly good but the tray tables were tiny so you couldn’t get anything else on the table. The seats hardly go back and are not overly comfortable. Wouldn’t fly United again.

The staff was great and made the long trip easy peasy!

The free Wi-fi for Aeroplan members was a great touch. The time passed quickly. I found the seats seemed a little closer together than I remember. Not Air Canada's fault, but we were about 20 minutes late landing because the airport was too busy. We had to circle around for a while. The boarding and disembarking went very smoothly.

It was great other than the plane was really small

The crew members were great. The flight was awesome. But I had trouble getting to any of the movies. I tried over and over. The free wifi though is a bonus which I appreciated. Re comfort I am not telling you anything you don’t know. There is nothing comfortable about air travel any longer. As someone with a back issue I am usually squirming about two hours into any flight. But safety matters most of all to me and I do feel safe with air Canada.

Had to cancel flight due to strike. Hope things will be better next August when we will rebook. Very disappointing as it was our 50th wedding anniversary celebration l!

I liked the behaviour of the crew members.The flight was good.

Short flight so no food or entertainment. Good landing at SFO and on time. We were told no carryon luggage yet lots of people were puting bags in overhead compartments. The rules need to be made more clear. I was on the first leg of an international flight and this is the first time I could not have carryon luggage.

Your crew was so so so wonderful Only thing sound be great if you kept some phone chargers and converters rest 👌👌👌👌

The speakers were way too loud. Music was played during boarding too. This noise could've been avoided.

Crew were friendly and efficient. Love the hot towel service!
