Food we select all the airlines, but they said not selected, it’s bad experience.

My seat was so hard and uncomfortable. I took AA to Japan longer flight no tailbone pain. Coming back on JA shorter flight my tailbone was killing me no cushion on seat or just worn out.

Not very much of anything, it probably was once of my least favore business class flights I have experience in all the times that I flew Boz class

I always enjoy flying with Japanese Airlines. The whole experience is always a pleasure. This flight was no exception. Thank you Kayak for making it so easy to decide.

Very smooth onboarding and offboarding. Food provided was cold and not the best.

Terrible experience. Staff would not even refill my tea once. While they refilled a fellow Japanese persons wine 7 times. They also lost my luggage. Horrible. Go elsewhere

main courses of the primary meal were not good- the beef dish was really not good-

Service and the plane itself were terrific, but the extensive delays both before we left and after were a real pain.

It was good and there is nothing to complain about .

The seats were narrower compare to other airlines traveling to Asia, which makes them uncomfortable after 6 hours The plane was worn, my tray table wasn’t level, You had to pay for WiFi and no Bluetooth option to use your own headphones. The crew was excellent in servicing the food and drinks. However I felt they needed some extra hands to serve the two sections of economy at the same time. They run out of one of the food option as they got to the rear section of the plane. Having travel on other Asian airlines during this trip; American Airlines can learn a bit from them, but I wonder if their service is geared towards a clientele that has become accustomed to not expect to much from an airline.

I enjoyed the flight, but a little too much turbulence on the flight. Thank you for the meal and entertainment. This kept my kids entertain during the flight. I have to admit comparing the crew from ANA vs United, there was a sense of more accomodation, friendliness and service compared to United crew. I felt for the United crew, it was just a job and it can be seen in there demeanor and delivery.

Attendants were very kind and frequently offered water and snacks. Food was excellent. For some reason, my IFE system would not play dialogue for any media despite my efforts to change to different language voiceovers, restart the system, etc. so I could not watch any videos.

Choice of movies dated as with the screens. Major room for improvement on the software to sort and select choices.

Although the crew was eventually very good, they complained loudly about EVERYTHING before the takeoff. Did not set the stage for a good trip in business class. The western meal choices were pretty mediocre as were the wine choices. We took an ANA flight to Tokyo and they were outstanding!

I liked the flight over all. Towards the middle of the flight. There was a flight attendant who felt like they were rushing to had out vegetarian wraps and said they were “sandwiches”. She also handed out hand we wanted the water but she was walked so fast we didn’t get any. We sat in the seat 45 E & D. And towards the last 30 minutes of the flight there was an announcement saying the crew would collect trash. No one ever came around. So held on to the trash until we landed and left in the seats.!

As always, there is that one or two flight attendants that could be better.

I loved everything about my experience!!! The staff were absolutely incredible. I can not wait to fly again with them.

ANA split my family of 4 by seating us each separately which didn't seem to make much sense. Both ways we were not seated together and the glitch int he online check in system meant we could not change our seats or get boarding passes without seeing a person at the airport counnter. The staff however offered good service in the air.

The seats were broken for several of us on this flight not to mention dirty. Quite unacceptable for the price point and expectation level. The meat was so hard it could hardly be cut so terribly unappealing. The united lungs in SFO was dirty and the bathroom conditions were down right disgusting. Nothing about this experience makes me want to book with United again. Our experiences with business class on Lufthansa and British Airways far out perform United in comparison. Truly disappointing!

I stopped flying with United back in the nineties. Today's experience reminded me of why.

Flight was late, the only reason I almost missed my flight was that my connection was also late.

Lufthansa seats were much more comfortable than United. While they had about the same video selection, Lufthansa didn't put advertisements in with the movies like United did. And the Lufthansa food was much better than United.

We flew business fares. Was amazing. However, the check in didn't offer business fares preboarding which is less hectic. 8/10 due to this. Staff compared to Canadian carriers go above and beyond. Would gladly fly United again.

The staff was incredible, very attentive, polite, made you feel like the center of the universe. They even all wrote me a happy birthday card. Truly just an amazing crew, cannot stress it enough.

Checking bag at terminal was horrible. No agents to check us in and only 1 kiosk working. Boarding went ok. Crew onboard was very scattered rained. Missed our row while serving and then didn’t see them hardly again.

The entertainment is a bit limited, it would be better if they added some games to play besides the movies and tv shows. But the seats are comfortable and the crew is polite

Food was great. Staff was phenomenal. Seats were a bit hard and could use a lot more entertainment options as far as movies to choose from. WiFi was good. Overall great trip.

Boarding was smooth and efficient. The only food was some pretzels, but it was a short flight. Not much to order if you were hungry.

Read the fine print. This was my flight home. I booked my flight for the quickest way home. Had a carry-on and a personal item. Same as my outbound flight. Apparently I needed to pre-pay extra for my carry-on. When I checked in, I was told that I had to check it. I said I’ll pay for it, and was told that this wasn’t an option anymore. They said I still had to pay $50 to check my carry-on. I told them I’ll pay whatever to just carry it in as intended. I was not allowed, so eventually I paid $50 to check my carry-on under a plane that was half full, with overhead compartments that were even less full. My white carry-on suitcase was practically destroyed getting from Idaho falls to Denver to Orange County. The low price air fair was a bait and switch. Got me to the gate, made me pay extra, then didn’t even allow me to pay for a carry on. Not to mention that I paid the $8 for WiFi that didn’t work. All to get my suitcase destroyed. I don’t think I’m going to even keep my Untied mileage plus membership and card. Apparently, membership does not have its privileges for this one.

2000 USD for a 10 hour flight on the worst seats I've ever flown in.

Everything was delayed and the staff sent me to the wrong gate, causing me to miss one of my flights. I arrived at my destination 6 hours later than I was supposed to.

On the return flight, arriving in Denver we sat on the tarmac in Denver for over 20 minutes.

The flight was fine. It's the satellite terminal that supports American eagle flights is what sucks. There is only one food option and everything there is way overpriced. I mean I know it's airport pricing, but it's even crazier than that. I bought a sandwich in a plastic container for $18.

Don't change gate multiple times make people run across the airport. Announce delays in a timely manner. Have maintenance crew ready. Don't delay and keep passengers on the plane for 3 hrs. on tarmac.

The flight attendant use 1.5 hours to answer my call. My dirty food tray was unattended.

Our bags took a long time to get unloaded once we landed.

Terrible. The flight was delayed two hours due to weather. Then when we got on the plane, the first pilot ended up timing out and we had to wait for a second pilot. Second pile came on board and we tax it out. Had to return back to the gate because of an unruly passenger. Then the copilot timed out. Had to wait for new copilot. Also had to wait for maintenance to check for fuel. Then found out the second pilot timed out and we had to wait for a third pilot. Was ready to go and then needed maintenance again for another issue. In the end, it was 2 o’clock in the morning when they announced that the flight couldn’t go because the third pilot and the second copilot had timed out.

One of the best flights I’ve had. So smooth.

Because I can’t stand very long in one place, I was allowed to reword.

Flight to Phoenix was delayed 1 hour and was not weather related. Flight Denver was delayed 2.5 hours and again was not weather related as the plane came from San Francisco.

Another good flight experience with Air Canada. The business section did not feature the full length sleeping arrangement, but this was a shorter trip. The food was excellent. But the flight crew was truly top tier: friendly, cheerful, helpful at all the right times. Air Canada truly outshines all U.S. carriers.

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.

In a nutshell, my bag, the one I have to pay for, because now you can’t even bring a carry on, did not make it. I am still waiting for an update. The fact that not only were have to pay for it, but on top of that we are stuck without getting it, it’s ridiculous..

flight landed late almost 1.00hr and we 4 passengers missed our connected flight to indianapolis, we need to get the hotel and taxi for the next day flight to home in indianapolis, cost us $ 300 more

Overall good experience. The flight from Toronto to Denver does not have entertainment - movies to watch.

Staff was friendly helpful also good timing I rate it a 10 out of 10

The only issues I have are the seats are very small and so is the overhead storage. You should mention that while booking flights. I had plenty of knee room but I am wider than my seat, and I am not fat at all. The Mitsubishi 900 models need to be upgraded to western size people. I do not know how a 300 pound woman fit into those seats. I had to continuously lean away from the aisle to keep people and flight crew from bumping into my shoulder. 3 hour flight so no entertainment or food, just snacks and a drink, which was no big deal. The buttery/garlic pretzels were pretty tasty.

I was overcharged either by United or sister airline Air Canada. It's exhausting dealing with companies nowadays that irresponsibly abuse access to credit/debit cards.

The flight attendants that assisted me were exceptionally nice, kind and helpful
