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

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 love Japan Airlines! I go out of my way to book with them. It is regrettable that the One World Alliance includes American Airlines though. The last leg of my flight from LAX to Austin was easily the worst, most disorganized part of the trip. Next time I will plan to fly directly from DFW to Haneda to avoid American Airlines as much as possible.

Leg room wasn't that great. Other than that it was a good flight

Issues: 1) the charging issue as described in my previous survey 2) when I requested diet coke during the breakfast time, it is not available. Why? I can't drink diet coke in the morning? 3) when I tried to transfer to this flight, its gate information was not available to me?

The lead business class attendant was excellent. Made a point of greeting you and knowing your name by the time you leave.

A lot of things Never flying with this airline again Had an emergency landing

Chicken pieces were too big with pasta. Need to be smaller.

Just want to do a little more clean up so does not smell like urine.

Check in process at the kiosk, crew in flight and overall comfort was good. Food selection could have been better. Flight from Hong Kong to Los Angeles did not have any vegetarian main course option, it was either sea food or chicken. Being a vegetarian I could only eat yogurt and fruit. Most international flights have one vegetarian main course dish which I found missing in Cathay Pacific menu.

Entertainment for kids was good. Good was terrible, needs lots of work.

Better. I took an aisle seat this time. Although the overheard compartment above the seat ahead of me kept opening up during flight.

They ran out of food and were offering random food to passengers.

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 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.

Great flight. Only complaint is it took over an hour for my luggage to get to the carousel on the return to LAX That was irritating

I knew I was going to fall asleep unsettlingly from exhaustion so I warned the guy next to me in advance. The attendant took to checking on me frequently and even insisted I take my snack because I said no while sleep hazed and then absolutely wanted it about 5 minutes later. He was So caring and kind to my situation!!

First message when all on board was that we didnt have a pilot, then they found one, then it was something about the bridge something not working, they will either fix or do manually. Flight of course was leaving late with all the cruise guests worrying about making it to their ship in time. Then only some luggage made it off the ship. Around 15 to 20 people waiting. 45 min later arrived except mine. I asked the rep at the luggage conveyor, he asked me my name. Then said it was not picked up with the first batch so they put it in a room. I was going to take public transport but now worried about time so took a taxi that cost me $65 USD

The flight was very smooth and good. Boarding was fast, but the staff was just decently friendly.
