Crew were welcoming, accommodating and they worked hard to find places for all carry on.

very average service no complimentary alcoholics drinks unlike other airlines such as Porter airlines No decent seats available during check-in time the day before

It was great. There were some issues prior to takeoff. The weather was poor so we had to go through deicing, and we were delayed a bit by the pilots' concern about one of the engines, but that's aviation. The pilots handled everything with aplomb, and kept us apprised

I dread trans-Pacific flights. They are very long. This was my first time on Universal, and it was my best crossing ever. The staff were professional, the hospitality was great, and the food was delicious. The entertainment system filled the long flight hours. I will seek out Universal flights from now onwards. 🙂

Horrific. They missed my connecting flight to San Diego. I didn’t get there until Monday at 9am when I had a mandatory court settlement conference scheduled at 6am since we had parties on the east coast. This caused many issues. All because United apparently forgot to hold the doors open until my flight landed that only had a 10 minute delay. This was the last flight to Southern California. So I couldn’t even rent a car to finish the trip. United cannot be trusted when traveling on specific days and times since weather didn’t have anything to do with the delays.

Was a pain having to leave the plane and reboard but glad the plane was fixed

Connecting flights were poor,especially in Naples.our Lufthansa air bus was a joke.way too small for that long of a flight.no room at all.couldn’t even get out of the seats to move around or go to the bathrooms.we thought we were getting an actual air bus,double decker.i will never fly that long in a plane like that again.kind of misleading to call it an air bus.we actually had more room on our buses that we used.

For a 22 minute flight all you expect is for it to be safe and comfortable

Lost connnection had to stayON in Chicago Was a mess

Booked economy through United - air canada treated it as standby and was almost refused boarding.

Nice crew - very small plane and uncomfortable, with no entertainment options…

We were given an upgrade which provided more seat room and a meal. However seat designated overhead locker space was used by others.Boarding was delayed with part or the delay due to staff assisting diaablef individuals aboard. Personal observation would suggest that 3 individuals rorted the system. They used wheel chair access to the plane, boarding with family ahead of al other passengers, but required no assistance until boarding occurred. On departure 3 “disabled” individuals were seen walking freely near the baggage carousel. One person even assisted with a luggage trolley! The rorting is most likely widespread and not airline specific

Not good with Kayak … There is no customer service number to call ?? We have stuck at Toronto airport but air Canada don’t help because we bought tickets thru Kayak .. Kayak should have customer service number listed for help .. Very bad .. we will think twice to buy the tickets thru Kayak next time.. Ahluwalia

We paid $110 for more leg room. My traveling companion’s knees were right up against the seat in front. Where was more leg room. We feel ripped off. Food,,,there wasn’t any not even a bag of pretzels. As a result, there was very little service.

A 6 hour flt and only offered water twice the entire flight. A small bag of flavored pretzels was offered as well w/ the first round of beverages. The landing was ‘hot’ but I arrived safely. The plane was nice and new and the seats were roomie. I’m use to warmer more generous hospitality but all and all I’d fly with them again but I’d bring more water and snacks.

Headphones for the movies have too much bass and can't be adjusted. Almost impossible to hear. Great movie selections but can't really watch them because you can't hear them. Also the system is very slow.

No food for a 6 hours flight! Plus very expensive to buy ! Sit uncomfortable! Awful!!!

Air Canada didn't properly check the maintenance status of the plane prior to boarding it's passengers on to the plane. A final check before liftoff and we had to switch planes because of mechanical flaps issue.

In the airport of Toronto, the person in charge a man with beard was an stupid person, he send everything to caos. Not helpful at all. Sunday to from 6:00 am to 8:20 am he was there, a people who work in front desk cannot be stupid and with that Ego !!

The check-in process was a disaster. 2 hours to check-in for PRIORITY boarding. We have never in over 40 years of travel experienced such a poor and lengthy check-in. Luckily, security and customs was nearly empty so we could breeze through it, and they intentionally delayed the plane half an hour to allow passengers to make it. The rest of the flight was as expected (in business class). But our luggage never made it to San Diego. We tried to locate and Air Canada rep at baggage claim but we were told that no one from AC showed up that day. I had to make a claim for our luggage by calling in to baggage services with AC and I was told that only because I had 75k travel status with AC would I get my luggage this week. Let’s see! I know many people that were waiting in line with me at Pierson missed their flights. Total disaster at Pierson this week.
