Airline reviews

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

I truly love flying with Delta. They have always treated me with the upmost respect

Our flight attendant in FIRST CLASS was one of the worst I’ve ever had. She was not at all pleasant, nor particularly good at her service.

Everything went well and was good. Nothing exceptional, but no complaints either. Cheap seats are pretty comfortable.

DELTA does a terrific job making sure you are well taken care of during the flight, gives you assurance before the flight through numerous email notifications about your upcoming flight & lastly good follow up after the flight making sure your needs were mat. It has been, is & will continue to be my carrier of choice in all my future travels. Good Job DELTA

Staff were friendly and happy. Delta could make sure passengers that don't have the app know of changes. Without Kayak I would not have known about the change of gate or the delay. Kayak was faster to notify me.

They ended up paying for the bag twice, but the counter wouldn't take my baggage receipt. Left it to me to resolve. Not sure how to resolve the issue.

The customer service before board was very rude and when I expressed my concerns about making the connecting flight she laughed and told me I bought the wrong ticket. I explained once it showed the flight was delayed it no longer let me change seats or anything. I was trying to upgrade to make sure I would get to the next gate on time.

Non stop on long haul is the way to go. Great experience

Seats comfortable, service and food very mediocre, staff not very attentive, worse than many other our flights with Delta.

Overall good experience; however, there was one flight attendant who was rather rough compared to everyone else. Everything else was good: entertainment, food. Delta keeps on delivering! Thank you!

We Left Calgary 1/2 hour late and that made for a tight connection in Denver. After arriving everything was done to help us make our connection. That was a great effort. Thank You United

The entertainment available didn’t work for anyone on the flight. Long 6 hr flight with no entertainment option and the staff didn’t know until an hour into the flight when we made sure they knew about it. They had no way to fix it.

Late FA meant slow boarding. WiFi did not work. I’m a medium plus sized passenger. The seatbelt was for the first time ever barely fitting. And we delayed on the tarmac 40 min

My husband and I had boarded the flight from Denver to Chicago, and one of the last passengers to get on the plane opened the overhead bin above my husband's seat and threw his bag out of the bin to make space for his own. He said, "Mine is bigger!" The flight attendant supported the new passenger. They didn't care that my husband has two artificial knees and must have the foot room in front of his seat to be able to fit his legs in -- and to be able to stand, much less walk, at the end of the flight. I have never seen this happen before, and it was a disaster.

I understand stuff happens, but plane failures are likely due to lack of maintenance. Additionally, air conditioning wasn't working, no snack/drink service, no WiFi. Fortunately, the crew was communicative and light-hearted. United grabbed another plane and we were able to get to our destination.

Had to cancel first flight because Airporter Bus took over 3 hrs to get to airport which resulted in an extra $378 dollar fare . Is there anyway I can be reimbursed for initial fare since it was not my fault? Sent from my iPhone EJ Ledet

Excellent flight. Boarding was efficient and departure was on time. Smooth flight with on time arrival. Deplaning was also efficient.

Our flight was understandably diverted to a small regional airport in Laramie, Wyoming due to weather conditions, which I fully recognize and appreciate. However, the low rating stems from the experience that followed: passengers remained on board for over an hour without the option to deplane and stretch, despite the aircraft being stationary. Although the pilot opened the cabin door, only he was permitted to exit. Meanwhile, passengers grew increasingly uncomfortable as warm summer air entered the cabin through the open door, and being in the second row meant we were impacted immediately. While the flight attendants made efforts to keep everyone at ease, I believe allowing passengers to deplane briefly, given the extended delay, would have significantly improved the overall experience.

I never flew. Flight was canceled. DIA worst airport in the country. Avoid at all costs.

Very rough getting into denver. my kid threw up it was so rough.

Good but need to be better with the flight times.

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.

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

I did not noticed baggage was separate - I had assumed international flights included luggage, so it surprised me I had to pay to check a bag.
