Airbus plane, nice and polite staff, entertainment even as it was a short flight.

10.0 ExcellentAnonymous, May 2025YVR - SFO

Airbus plane, nice and polite staff, entertainment even as it was a short flight.

Very nice and clean plane. Transit time between flights was tight though

Our flights got changed from United to Air Canada and our purchased seats did not get transferred so we had to pay for seats twice. I brought it up with Air Canada and they stated I had to go back and chase it with United. The united seats were $21 Canadian each and Air Canada were $56 each so we have paid $77 for each seat. Very unhappy

So far so good but food and entertainment are not available for this flight

Plane temperature was comfortable (not to hot) when boarding and waiting for takeoff.

Michael, our FA was very attentive, even finding me a chocolate brownie from economy class when the dessert selections were all dairy based. ( intolerant, not allergic so don’t usually need to order dairy free)

We tried to upgrade to economy premium but were told this was not possible as we had booked through United Airlines (and Air Canada was operating the flight). This seemed silly given there was ample space in economy premium. Additionally, we had to wait almost 1.5 hours upon arrival to taxi to the gate. Otherwise, the crew were very pleasant and passengers were friendly.

It was my first time with United Airlines and I would say it was very good experience and best of all the flights were on time. Will definitely fly with United Airlines next time.

headphone jack didnt work for the first flight and not much variety

Plane 3 hours late. Missed connection. No help from gate staff. App horrible. Lost connection repeatedly. No service desk. Finally got help from young girl driving cart.

Just a little improvement on food but everything is excellent

This was actually a bus ride to the KW airport. It was smooth and comfortable and on time.

In flight WiFi not working. entertainment system not functioning Food was mediocre poor for business class Service was ok but not excellent Crew were pleasant. Announcements were made at a ridiculous volume.

Food, service and the boarding/offloading aspects were great. Our only issue were the seats we booked in the exit row because it was next to the bathroom so we were interrupted all night by people waiting for and then opening and closing the door to use the facilities. Would have fine for a day flight but not so much for an overnighter.

Somebody either kayak or Air Canada booked my flight under my preferred name Betty instead of my legal name and I almost was denied boarding my flight

I will never fly Air Canada again. 5 hour delay due to plane problem which could have been fixed while plane sat empty. We offered a $15CAD voucher for dinner due to delay, BUT that is NOT Even enough for a hamburger. Air Canada rebooked my 87 year old mother on an onward flight in Munich with NINE HOUR layover without rebooking me on same flight. Air Canada apparently cancelled my onward flight as I was offered a refund for the Lufthansa leg from Munich. Fortunately, Lufthansa Service Center staff was very helpful rebooking us both on same flight which was one hour earlier, so only 8 hour layover. Lufthansa airport Mobility staff as well as plane crew were awesome and extremely helpful with wheelchair support. Spoke with others who were on same flight from YYZ to MUC and there was at least one other person that was not rebooked onwards (from Munich to Hamburg) by Air Canada but was able get support frkm LH Service Center staff. The Air Canada plane crew was very helpful, so the overall issue is Air Canada systems, and gate agents that have caused multiple negative issues on AC836 YYZ to MUC on May 18th. Similar to what others on this flight have said, I will NEVER, EVER, NEVER AGAIN fly Air Canada. And I've likely flown over 1 Million miles with them, with lots of miles in Business Class and have held Elite, and Super Elite status.

Good flight, slightly cramped as the seats are very close together

SIX HOUR FLIGHT DELAY!! $15.00 voucher to apologize. Missed our first tour in Quebec.

Terrible food, unprofessional flight attendants, and an uncomfortable seat. The food they provided was the worst I have ever had since I flew. They were worse than any cheap food you can get at convenience stores. I feel that a racist looking fight attendant was scanning me as she was passing by me. A man sitting in front of me fully extended his chair to the back, so I had virtually no space to eat with reasonable comfort. Many people were so inconsiderate of others and fully extended their chairs to the back that they did not have enough space to eat. Flight attendants ignored these situations and never bothered to tell passengers to return their chairs to upright positions during the mealtime. I want to be comfortable and don't care if others feel uncomfortable because of me. Those were the dominant thoughts of people in that airplane. I paid more than $2000.00 for this terrible experience.

Everything was fine, crew was great. Always appreciate an on-time flight.
