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

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 avoid American Airlines for a reason. Our flight was delayed at LAX. The situation at the gate was chaotic. The woman making announcements wasn't being clear or transparent regarding why there were delays. There was a lot of confusion regarding flight and gate status. Other passengers were pretty rude. I was elbowed in the eye by someone who was in a hurry to get their bags from the overhead bin immediately after the flight landed. Ultimately, I will avoid AA as much as possible in the future.

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.

Issue 1: We had a 2 hour delay to repair a windshield wiper, during which we sat on board on the runway. Issue 2: it was VERY HOT in the cabin for most of the flight, we were sweating. We asked to make it cooler. They didn’t succeed in doing so. Other than that, it was great. Fantastic food, and extremely pleasant, accommodating flight crew.

We asked for Hindu vegetarian meal in advance and the quality of the food was horrendous. Never flying JAL again!

My total experience was good. The food and entertainment need improvement.

I wish I was able to flew with JAL all the way to DFW. After my JAL flight to Japan it was taken over by a flight with AA which is another experience, the plane was not as roomy like JAL. I was terrified to drop anything in the floor and not have the room to bend and pick it up. My wifi din not work at all, l just slept through majority of the flight. Although not a bad experience, I still wish that I flew JAL straight to DFW for the experience.

Overall pretty good experience. It would be nice to have caught the attendants even they were flying down the aisle with snacks, and if they could cater to multiple dietary restrictions (bland and no lactose. The customer service chat is a bad experience), but otherwise no complaints.

There was a flight attendant named Angela who took care of me because I injured my foot badly right before the flight. Because of the service she provided I will always fly Cathay.

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.

Great. Efficient boarding process with the face recognition. Plenty of cabin space for luggage.

Cabin crew is very helpful and nice, it is another level of service compared to Air Canada

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

The food and service was great. You have to pay a lot for in flight Internet though which is lame.

Flight was delayed at the last minute for six hours. Instead of delaying it to a normal hour, they moved it to 10 pm to essentially make it a redeye. There was no compensation or benefit offered for this inconvenience. Once on the plane, Inpaid for WiFi twice with both times it not working because of a “weak WiFi signal”, according to the flight attendants. They also chose the farther possible gates in both airports from the entrance/exit, even though they were one of the few active flights left so late in the evening. Overall it was pretty horrible.

I had high expectations but met with a below average experience. I hope the Airline will take a notice and improve.

Boarding was organized. Plane seats comfortable and service was attentive. Food options were good.

This was a very average flight. The seat was out of alignment so more uncomfortable than usual. The cabin felt not well maintained. But I safely got where I needed to go.

Trip was great. A wild landing in Ottawa with the wind and rain, but the pilot did a great job. Always love flying United.👍

I will never book a flight through Cheap fare. They booked me from Portland Main . And would not give me a refund, so I bought 2 tickets one for 299. From Portland Main to ORD. Then I had to buy a ticket from Oregon PDX to ORD that was another 440. So Just so you know they even told me it was there fault but no refund. Bad bussniess. I did inform United but they said they couldn't help me due to the fact I booked through Cheap Tickets. Never again. And I'm spreding the word. I let everyone know at my 50th class reunion

The internet service I paid for didn’t work at all and the flight crew was not very friendly.

Excellent experience. Starting with the agent at the Premier bag drop who noticed I was very early for my scheduled flight and offered to rebook me on an earlier flight with my seat preference. She would not let me leave the counter until she knew that all of the changes and new boarding pass showed up on my United app. At the gate, the flight boarded quickly such that we departed early and the flight was smooth. We arrived 20 minutes early at ORD and I was able to be home in time for dinner. One of the best flights I've had.

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

Salina to travers city was great! But the sept 24 Tranverse city was not! Traverse city to chichago was cancelled, i went to Denver & got to Salina 6 hours later!

Flight is clean and ontime. Crew is friendly. Snack can be better and the internet connection is poor

Crew and customer service were excellent. This flight also had plenty of leg room and seat mounted screens for entertainment. A very pleasant flight all around!
