Unbelievably smooth boarding at IAH and the flight attendants were top notch.

Comfortable seating POS to IAH. Food options were satisfactory. Good seat from IAH to ANC. Food options could be better.

There could have been better food options in economy on the long 7hr trip from IAH to AM.

Great experience. Boarding was fast, staff were very nice and funny, everything at the seat worked well.

Uncomfortable plastic seats even in premium economy. No free wifi. Even paid wifi was spotty to nonexistent. Bad food. Much worse than economy on foreign carriers like Qantas.

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

I found the staff to not be very attentive at all. When paying for Business Class you expect a certain type of service and that was not found. They were almost rude even

Great. Food going from Australia to the US was better than other way around, but still needs improvement in terms of quality and quantity!!!

Flying to anchorage would have been cool but the weather got in the way

Due to a cancelled flight the day before this flight only had 44 people. Best flight ever on international route. Food getting better. Can United provide fruit ex apples and bananas for snacks? Crew fantastic.

Everything was great except that I wasn’t issued a boarding pass for the second flight so they would not let me into customs until I had said boarding pass. Luckily a gate attendant from another Air Canada flight was able to print one for me so I could go through.

The flight attendants were not very nice. No smiles On my return trip I was charged for one bag $83.30 although I had purchased the flight including one piece of luggage. Can this be refunded to me? Thank you!

Full compliments to Captain for all four landing. Crew could be more polite and nice.

So smooth and easy! From boarding to arriving, we are very happy with our experience on air Canada.

There was a long delay on tarmac. The pilot kept us informed. The flight stewards were not entertaining or comforting. During the flight we received minimal service. Several food choices for purchase were not available at our seating of row 52. Only twice were we offered water for hydration. A half hour before landing teh pilot acknowledged that some passengers with connecting flights should tell flight stewards and they would help.. We had a connecting flight thand at should have had a 2+ hour layover and now would be less than 1 hour from departure. The flight attendant told us not to worry.. plenty of time. We did not get off the plane until after 6 o'clock. We are seniors (ages 74 and 72 ) and had to walk the length of the terminal to go thru customs and the length of the next terminal to departure gate for 6:30 a boarding call. We ran and were breathing hard and reached the departure gate by 6:50. We rate the flight stewards negatively...the pilot did his best.

It was very bad travelling with air canada the people working at check in bagages was very bad person any way I pay to much many to get good flights but it’s not

Air Canada switched my connecting flight to Alaska airlines without any communication to me. The process of finding this out, needing to leave one portion of the airport for the next and what i should have done with my luggage was not communicated to me at all. Even the Air Canada agent that noticed the airline switch at the terminal did not explain this process to me. In doing so my luggage did not arrive with me. The delay to create a claim too 2 hours.

Food was great. Staff was great. I would have liked to see more in flight shopping - they went by so fast I missed it. I would have liked more variety in tv shows but overall flight was great. The staff made all the difference.

The bathroom I used could have been cleaner and tidier. Didn't look like it was kept very well. The staff were super helpful. There was an issue with my screen, and they rebooted it for me. They were also great at dishing out our meals, and cleaning up after.

The seats were very nice. The flight attendants were obnoxious and rude. I felt that if I asked for something they would bite my head off! When I did ask for something, they said they would do it after they finished what they were doing, but never did. Horrible. Check in at business class took way too long.
