I thought this was a JAL flight but landed up being a code sharing one with Hawaiian Air. Got upgraded by check in staff and they confirmed my bag coming from Bangkok which was great. Cabin crew was solid, not especially friendly, just super efficient and wanting to get the job done which they did. Very fast and agenda oriented. Worst part is my economy plus seat was no better than my economy seat on JAL. Plus JAL has way better food, cleaner plane, and better crew. Worst part is when I landed, was never told where to grab bags. I had correct flight name and number for JAL but there was a Hawaiian flight number in another baggage terminal. I wasted over an hour with no help from ground staff for my bag. Hawaiian and Alaska airlines merger can’t happen fast enough as Hawaiian airlines is a dinosaur. Bad experience again and I’m not surprised. JAL rocks!

The seat was uncomfortable and seemed to be on its last days. Loose and sloppy

Business class lie flat seat is the best and easiest to operate 👍👍

My seat had zero leg room. I thought I was flying Japan Airlines, a company I picked based solely on the legroom... When I got to the airport on my first flight, they informed me that I was in fact flying J.A.L VIA American Airlines... What a bait and switch. I will never fly AA on an international flight ever again.

put me in front row, screen was tiny, movie slection wasnt very good will be flying back on another airlines

Excellent flight. Check in experience was a breeze. Smooth and on time flight. Friendly and attentive attendants. Premium economy seating was very spacious. The lounges in both SEATAC and Narita were first rate. The only negative was the inflight food and entertainment options, which were limited, and Wi-Fi was not working. We would definitely fly JAL again.

Not good. The flight from LAX to Tokyo was delayed 15 hours.

My luggage is missing and waiting to hear back about it. 3 of my 6 checked bags didn’t make it to DFW.

Boarding, crew, and seating were great. The food needs to improve.

JAL is an exceptional airline that shows the true heart of Japanese omotenashi service. If the option is available I’ll always chose it

7 hours delayed due to operational issues on United’s end. Basically laziness.

Short flight but an "eager to help" crew made the journey more enjoyable!

Not enough veg food available for passengers. I actually did not get the veg food and was told it was over, and I starved the entire flight duration.

Flight was delayed only slightly before takeoff due to traffic control. However, the flight arrived early to ORD. Good flight. United has been very reliable for me.

Flight left on time. Boarding was easy. Arrived to EWR 30 mins early. Luggage was deplaned in good time. Overall a very good experience.

Flight from Rome to SFO was excellent compared To our flight to Europe from SFO. The food was much tastier. You can see how UNITED is skimping, though. Instead of getting something mid flight you had to ask for it. It was not automatically served. There was a cookie at the end of the arrival meal, for example that tasted like it just came out of a box. They used to serve a little container of nuts, now … a tiny container of nuts, mixed with pretzels. This was business class that you really have to pay for! But this is minor complaints compared to the overall. My major complaint is the position of the even numbered seats by the windows. You have to turn around to see your window & the positioning as some other controls are harder to get at. This is compared to the odd number seat that are perfectly aligned.

The person I bought the ticket for didn’t make the flight.

Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.

Another delayed flight. When the delays exceed the duration of the flight, it’s a problem.

Excellent flight. Smooth, efficient boarding. Quick flight. Arrived early at STL.

The staff could not have been any friendlier. Lots of usb ports on our aircraft.

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

Air Canada cancelled our flight and reschedule it 26 hours later that completely interrupted my family's long waited Japan trip, it wasn't due to natural reason such as weather but under the company's control. On the day we wasted 9 hours of our time from 6am to 3pm, including a few hours in the customer counter waiting for supervisor to handle our rescheduling. When we came to the counter for rebooking help there were at least 4 employees on the counter but we were told they were not trained to handle customer rebooking, we were also told the supervisor could come 10:30 to handle our rebooking, but she showed up more than one hour later, the end result was exactly the same so the few hours we spent waiting for her was completely wasted; We already prepaid hotel and all the tickets for the our stay in Tokyo so all of the cost for the first day is completed wasted; The $80 meal voucher issues was far less than our financial loss due to the financial cancellation, and it was not surprisingly invalid (as Your company screw up everything possible along the flight), the vouchers were supposed to last 72 hours, when we tried to used it at our lounge next day less than 24 hours from its issuing at a designated restaurant, the worker there couldn't scan the vouchers after multiple tries on all 4 vouchers issued, so we had to pay the food from our own money; For the two return flights they were also full of unfortunate events that caused bad experience and further delay and waste of our time, both flights departed late and the last leg had another significant delay of more than half an hour after touchdown, the gate was for some reason not available so we waited more than half an hour, when we got out of plane it was almost one hour later than the supposed arrival time; The gate you arranged is the farthest in Vancouver airport, also was the luggage pickup location in Seattle airport; We also called customer service for rescheduling help and after a long time wait (more than an hour) we got a call back but the CS representative was equally clueless and unhelpful. Other than a fatal crash, your company couldn't do anything right and provided the worst service possible among the tons of flights we have taken in our lives.

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 crazy, boarded over a hour late from scheduled departure. Then when arrived in BNA issued with getting off the plane…over 1/2 hour. Not looking forward to flying Air Canada, ever again.

Extremely turbulent landing. Crew was friendly and plane comfortable. Airport and US pre clearance was understaffed

The cabin crew was professional and there were plenty of movie choices, but the food was a bit sub-standard.

The airplane is way too tight, you can hardly enter into your row to sit.. more like kids seats than adults.

taking our carryon and forcing us to check it through

Wifi was great. Kind air crew and comfortable seating. Also liked the entertainment options.
