It was smooth and quiet both ways. Staff was attentive and very friendly.

Horrible and the food was disgusting as well as the delays for the flights and luggage

The best in every respect but the best was the departure lounge at Narita which had the best tasting food ever at an airport lounge-great variety of food and drinks and the Japanese food, from rice curry, chicken karaage to all the side vegetable dishes were the best! The staff was very attentive and courteous. Best airport lounge I have ever experienced!

It was super duper delayed but Japan Airilnes service is great to be fair specially their attendants are very polite, pleasant and nice ! Food is good also.

Very poor experience and will never travel with JAL again. With Business class ticket i was told that there is no veg option for the 1st leg of my journey from Delhi to Tokyo while served horrible plant based meat on the second leg of journey even though i selected Vegetarian meals. Also entertainment system is worse than domestic flight with hardly any Hollywood movies and no hindi movies at all

Good. The only thing is that I missed the flight.

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.

Refer to the Osaka-Tokyo one, it explained how I felt about both flights

I am a United 1K flyer but certainly I would fly ANA again. Great inflight service!

"The Room" is the only way to fly. The service was excellent and the stewardesses we all gorgeous and friendly. The boarding process was delayed and the attendants at the airport were not the best.

Great. Very helpful staff and accommodating. The flight was also smooth

My son flew and had a great experience.. thank you for taking care of my baby

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

Seats needs to be wirer and food is very poor

Pretty much the exact same comments for this flight, there was crazy weather!

I have been flying united for a long time but now I’m done

1) United economy seats barely recline. 2) I have yet to get United WiFi to work, after numerous flights.

Return flight was perfect. All on time and no hiccups. However, going was another story. I don't blame United for the weather, but I am rather disappointed in its response to my getting stranded in my layover city for the night. United gave me a $20 food voucher. That's it. But besides this policy, the employees were incredibly helpful rerouting me to my final destination in Fort Lauderdale, FL. So overall, 8 out of 10. 10 out of 10 for flight comfort, inflight service and before flight service. 5 out of 10 for layover handling.

Santa Barbara is a super small and easy airport. Breezed through rental car return, breezed through Security, ordered a coffee and muffin and to my gate in less than 30 minutes. Maybe because it was a small airport we got the oldest plane. Hardly any overhead space and absolutely zero internet. Its NFL Sunday man! That hurt.

There were no vegan options for first class. Even though we were promised the satellite internet for free, we received NO wifi at all. Even though we were promised a 20-min early arrival, we ended up over 30 mins late.

Flight attendant incredibly rude. Stuck her finger in my drink and didn’t even have the courtesy to apologize.

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.

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

After we boarded, we sat on the tarmac at least a half hour. Not that big a deal really but kept me from giving the survey an excellent.

Staff never asked passengers to bring their seat backs forward during landing. Was hoping to get a little relief from the passenger in front of me (I have long legs that I cannot stow in the overhead). Otherwise the flight was very pleasant.

We were told every hour that the flight was delayed until finally late in the day the flight was cancelled. We had to wait in line over an hour to finally get another flight. Once on the flight the host was ridiculously incoherent in the loudspeaker in flight - very inhospitable. Not happy with our experience.

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

My feedback from the trip to Columbia to Chicago was meant for Chicago to Denver.

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.
