Purchased WiFi was slow to non functional. Staff was not personable or friendly. Seats were cramped. Boarding took long but I expected that.

Luckily I just tried to sleep. But the entertainment system was awkward to operate. I hate all this stuff with apps and adding it to your phone and all. It is a nuisance. I would prefer a good magazine or newspaper in the pocket in front of me or available.

The seats are uncomfortable. The flight attendants are not pleasant. They do their job, but not with a ray of sunshine and warmth. The food was awful, not what I would expect from an Asian airline. All of the other Asian airlines I have flown have far better food. The food was on par with United airlines food, which is really bad. Maybe ANA should get out of the alliance with United.

One of the best 14 hour flights I've ever had. Crew was friendly throughout which can be difficult on longer flights. The crew being kind and respectful is very important for me. Plane felt clean and I was able to get some well needed uninterrupted sleep. I put them slightly above Cathay Pacific as far as cleanliness the only down side was a lack of entertainment selections, but hey I am an American taking a trip on a Japanese airline so I cannot complain. Thank you ANA and the Tokyo airport all very friendly. Will see you soon

Poor. We weren’t able to check in online (for several hours until we gave up) for no apparent reasons although our passports were loaded successfully. When we were at the airport check-in, a rep helped us at the kiosk but she disregarded the KTN provided to her so we had to come back for it after being questioned by the TSA person…

ANA gave me an amazing experience. They are very good with customer service.

Flight delayed by one day and everything was so disorganized by the airline.

Everything was good may improve some alcohol drinks and amenities during fly

The crew was amazing, really friendly and efficient. One of the best flights I have ever been on. They made the long flight comfortable and I noticed there were two birthdays on the flight. They gave to customers birthday cards and wished them a happy birthday. That was very nice to see.

Everything was great. Wifi was down,but that didn't matter to me.

highly recommend for trip to japan only reason why i gave good not excellent is because their selection of movies and tv shows in English is more limited .

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.

Overall a great experience. One complain was the vegetarian food that my wife had which was mostly boiled vegetables with not much flavor.

We booked business class round trip from Delhi to San Diego and back. On our last leg from Bangalore to Delhi we were down graded to economy class which was big disappointment other than that everything was great.

Had an incident with a stewardess who insisted that I take a seat. I informed her that I came to use the restroom and to have some water. After using the restroom, I wanted to stretch my legs out a little cuz my knees were aching from sitting. I understood her concern for my concern and the potential turbulence (she said she knows this route and the turbulence and safety is not to be taken lightly) but I felt that her mood, tone, demeanor, and a lack of compassion for the pain in my knees were not the proper way to address a customer or anyone for that matter. This left a bitter taste in my mouth. It was her lack of professionalism that surprised me.

It was good but need mor amenities for toiletries and entertainment

This portion of the trip from HCMC to Dallas was operated by American Airline. Unfortunately they are 2 steps below JAL in overall quality. Regardless, AAStill got me where I needed to go on time.

First experience with JAL so was okay to pretty good. 10 hour flight in premium select seat. . Seats in that category should be better than pretty good. Seat pan a little short for tall people but plenty of leg room; I think JAL in process of new planes? Also, — they could have offered a bit more water throughout flight and meals not the greatest. That said, certainly 200 percent better than a very recent AK Air International flight in similar cabin class in comfort and meals.

We ordered for non vegetarian Hindu meal but instead they served us vegetarian Hindu meal. That was also not good. It was very annoying and aggravating. Hope our return from Tokyo to jfk on March 27 same is not repeated. Caterar should understand difference between non vegetarian Hindu meal and vegetarian Hindu meal.

Food was great, Entertainment was bad, movies were not current and just did not have good variety. Granted I was tired so cranky might have played into my evaluation. Overall based on cost I definitely would fly them again. I am a million mile flyer on another airline, the service on JAL really beats all airlines.

My experience on any Delta flight is always overshadowed by the time Delta removed me from a flight for no apparent reason.

Delayed and took off even later than the scheduled delay time

For a 69 year old with health problems I had the worse experience, no wheelchair when I entered a lady told me to sit and wait while a gentleman told me I had to walk to the Delta station, which I did. I had a carry on and a bag, and I was traveling with my service dog, which was on his carrier and the lady charged me for my carry on luggage, beside all the waiting cause of the delay, I had to walk to get my luggage cause no wheelchair showed up, I am so disappointed. I will get in touch with the company. I got home at 3:00 am, not good for my health situation.

Only issue was with seating. The economy fare we purchased did say there was no guarantee the three people in our party would be seated together, and we were not. At the gate, the agent told us more specifically, the fare we purchased meant we would be seated in middle seats only. This should just be made more obvious.

Great experience on Delta. Staff from baggage check to flight attendants were very courteous and professional. My only issue was a personal preference for pretzels instead of the chips and cookies that were offered.

There was no problems, just a little uncomfortable with seats that do not lay back a little

Always good but we must do something about people in rows ahead of you that don't put their seats back up when they are suppose to. And It's rough to not be able to even lean over to get something out of my purse.

Flight was delayed, 30+ bags had to be gate checked. Crew were very friendly!

Everything was good until we were boarding our connection flight in Atlanta, we were told to gate check our carry-on, but when we got inside the plane, there was plenty of room in the overhead.

Did not know my son and I had different seating arrangements. He was fine, but it was disappointing.

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.

Paid a premium a have a shorter transit time in Hong Kong, but Cathay pacific rebooked me and ended up waiting for 10 hrs in Hong Hong airport.

Short staffs, I ask stewardess to bring me cognac twice during dinner but they didn't bring it!

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

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

I've stomach problems after 2 hours of flight, Iris, the flight purser not only did her best to make me feel comfortable, she went above and beyond providing pain relievers medicines and ointment. She look and found a doctor passenger on the flight to provide advise. She even report on ground staffs about my condition and provide wheelchair upon arrival. Kudos to her and Cathay Pacific!

Worst experience I have ever had with any airline in over 25 years.

Crew was great. But a bit understaffed. The business class seat, etc were dated. But comfortable. Some legs had entertainment system from a decade ago. Selections were rather poor. Food was mediocre at best. Actually poor for business class standards. I liked the lounge in Hong Kong. Showers were great. Food was nice.

Everything was fine and I have no complaints or things to note.

The economy seats are much indeed roomier. Meals needs improvement.

Terrible. Delayed 7 hours, and cancelled the flight, leaving me stranded and out of pocket $500 for an alternative last minute flight

Was on time until within 1 hour of flight-how does that happen? Staff very friendly.

the delay for 3 hours was understandable due to weather conditions but the flight should’ve provided some on flight compensations or at least provide more food.

Weather delay in Chicago?. No sense of urgency to make connection in Chicago for our connecting flight that wasn't delayed. Connection was missed.

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.

I learned that seating towards the end of plane that a line forms for the restroom and people use your chair as a hand railing, bumping your seat consistently. I was seated in the aisle. I think that next time if I am towards the back row I would want to sit in the middle or window seat.

The best airline I have ever travel , really good customer service, attention and service !!

United could have one single once of customer service. No human United employee would help me with the invalid mileage plus number, they said I had to speak with the computer.

United sent me a mileage plus number last year but that number is invalid so I can’t use it to check into flights or collect mileage. There is human to speak about the problem, only computers who keep asking me if I am using the correct email. It’s so frustrating and I cannot resolve it.
