excellent, food was great, the crew were excellent and very accommodating. thank you very much

Excellent. All the ticket prices have gone up so much. With only economy as the option, I thought I better pay for a good airline and I am glad I took ANA. The only thing is the long layover at Hanaeda enroute to Singapore. Any chance to bring back the service to land at Narita instead for the transit and a shorter layover will be fantastic. I am a fan of ANA.

Incredible. Amazing legroom. Over head fans for each person. Tv screens were great. Headphones were adequate. Seats were comfortable and spacious. Loved it.

Flying with ANA is always a breeze. Seats are very comfortable.

Flight was on time and the crew was as expected, friendly and respectful. Food could’ve been better though.

First I will say this was really NOT an ANA flight. ANA used a UNITED jet to perform this flight. I specifically booked with ANA because I did NOT WANT TO FLY UNITED FOR INTERNATIONAL FLIGHTS. So to spend $1800.00 and then discover after booking that it was going to be handled by United was very disappointing. I will be more careful next time when I book. The interior was very cramped in economy class; the dinner meal was terrible and also had extremely small portions for an international flight - the bread roll was ice cold and stale - that salad was very wilted; I’ve never had a “snack” that was so salty that it was difficult to eat; the breakfast “waffle” was practically unrecognizable. Really horrible meals for a very expensive international flight. Bathroom floor was also pretty dirty. I’m hoping my return flight is a real ANA airplane that is cleaned and serviced by ANA personnel with ANA meals. I will never book with ANA again if they continue to use UNITED airline jets. Yuck!!!🤢

Ticket was purchased as a United Airlines flight (operated by All Nippon) like what does that even mean? Makes for a VERY confusing flight experience. For instance, what do I look for a United drop off signage and ticket counter or ANA? No explanation anywhere to be found. I also felt a little bit scammed by the obsurdely restrictive seat selection provided. Only middle seats available!! Are you kidding me!! On 6hr + 10hr flights you're forcing me into the middle seat without telling me before I purchased the ticket?? This should be illegal. And to top it off, on the Tokyo LA leg there were quite a few empty seats including window seats! I must also say, the food was a dissappointing as well for my taste, fish with rice ( mostly plain white rice) or a vegetable medly for the breakfast meal? Should be at least 4 choices and at least 1 with eggs. Outside of these issues flight was otherwise ok.

This is a very long flight and the first time I have flown on a Japanese airline. I was very impressed with the staff. They worked hard and offered food and drink regularly. Plane was very well cared for. The let room was good . Food was ok but better than other airlines.

It was very nice. I was a bit disappointed by the few meal services. There were probably more drink services that I missed while sleeping, but I would have liked the crew to bring more than one drink service before landing and to bring more than one drink service and coffee service after take off

I wish the serve should leach and drink. Maybe because only 2hr

Overall mediocre-good, with the service on the flight operated by American Airlines being subpar and not the kind and standard you’d get from a Japan Airlines crew. The majority of the stewards on AA were not as gentle and friendly as those from Japan Airlines. Japan Airlines were more attentive to detail and your flight experience. AA was more interested in completing their tasks.

All of the JAL flights in this itinerary were great. However the last leg of my flight from LAX to SFO was through Japan Air’s partner, AA which wqsn’t up to par. We were informed only minutes before boarding time of a delay despite the airlines knowing about the delay far earlier (the aircraft we would be taking arriving arrived and disembarked close to our boarding time, for all to see but AA still kept the original boarding time posted until last minute). Furthermore, once we boarded the taxi/wait time was also extended, with the pilot blaming “construction at SFO” for the delay, rather than taking accountability for the the plane’s late arrival coming into LAX. We took off approximately an hour later than scheduled. It’s for these reasons I adamantly avoid American Airlines when possible. Again, JAL was stellar.

I like the braised beef., miso soup,, and green tea. Very little choices of hollywood movies. The PA announcement in English was not very clear and very soft. I could hardly hear.

More updated movies & Chinese movies. The food sometimes overcooked. Prefer to have more neat snacks in between than just choose from the menu. Please change the menu every now and then. This is my second time flying within one year and the menu didn’t change at all!

Food is lagging. Very poor choice. Like vending machine fast food.

Please change the menu more often. The beef is not tender, more choice in ice cream flavor. Dessert is not good too.

First of all I had dozed off. And when I woke up, my food was on a tray without telling me the food was there or asking me if I wanted something to drink. They never came back to ask me if I wanted anything to drink and I tried to stop them several times. I personally have a problem swallowing food without something to drink with it. so therefore I could not eat., second thing for the entertainment. There was no place to plug the headset in because the tip had been broken off into the monitor to where you couldn’t even watch a movie or hear any music that was annoying .

Again I paid for an upgrade on my credit card didn’t get it need a refund. . American I not good at gettin in contact for refunds.

I didn’t like the check in process I had to check in at the counter took too much time . Didn’t give the upgrade my seat .

l enjoyed the variety of good and drink choices. The flight attendants were very quick and efficient to our needs.

Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

It was pretty good I was worried with the short Layover that I might not catch my connection but the gate was there

It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

Friendly flight attendants. Comfort plus seats were very comfortable and had lots of leg room. 10A and 10 B.

I've flown many many times on Northwest and then Delta. The crew on this flight were absolutely the best I've had the pleasure of being looked after by.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Awful. Flight was continuously getting delayed and gates kept changing without any reason. Flight was delayed for more then 3 hours

Paid premium for Delta only to be on safe but tired old 767 with ancient cabin in mediocre condition. Poor wifi and horrible inflight entertainment. Hardly a premium experience. Should have flown SW and had fun flight crew and no pretense

After the morning frenzy of 35 min wait through CLT security at 4;30 AM, it was nice to have a smooth pleasant boarding experience. This 6:30 AM flight was not full. We were able to get seated swiftly and took off promptly. Nice touch they distributed the old fashioned headsets with 8 mm jacks. Snacks were decent and arrival was uneventful.

My window shade didn’t work. So I missed coming into my city. ☹️

Flight was delayed in the gate by 5 hours and ultimately cancelled- rebooking service by United agents was terrible

Everything was pretty good except for food. They need to improve on it compared to other airlines.

Flight was delayed due to the late arrival of the catering truck, which is quite unacceptable. There was a beverage service, but no pretzel, or cookie, or nuts were served in coach.

Not worth the premium paid for the first class ticket

Not worth the price of premium class ticket paid, felt more like steerage.

Flighty delayed on boarding - then group 1 had to check their carry on bags but groups 3 and beyond could carry bags on - very inconvenient for weekend business trip with no checked baggage. Then delayed on the runway - before take off. No communication from pilot on why or how long. Wifi/Entertainment didn't work for 4+ flight. Upon arrival, attendants announced wrong carousel for baggage claim - everyone was waiting at the wrong place for their checked bags. This was a mess united!

I flew Delta last week and United Airlines is a poor substitute mechanical problems with the plane and shitty food among other things made my travel experience what’s become to be expected from United no way is it ever worth the money they make us pay

I had a great flight. Everything went smoothly and the flight arrived early.

The flights was delayed by hours and it was the firmest landing I have experienced in my life. My back is still sore.

Internet service was erratic. Crew service was poor and slow. My luggage on this non-stop flight was lost and not recovered

Terrible. I didn’t fly and I had an important meeting the next day.

Missed this flight due to the first AA flight delay

Equipment swap led to 2+ hour delay on international flight. And to top it off, boarding took forever.

Wretched scheduling - they got themselves into a critical crew situation and didn’t try to address it until 15 minutes before they had to cancel my flight

They cancelled two flight and got us onto another airline, which was also delayed.

Nothing, terrible travel experience due to weather and maintenance delays and was left stranded in Austin.

Missed connection from Philadelphia to London because flight from DC was seriously delayed. Was re-routed the next day (had to pay for hotel) to Zurich and was given a main cabin middle seat while I had paid for premium. Great job AA!!!

My husband and I pre-ordered our food, but they did not have my husband’s order, and my cheese plate was very average. I asked for a blanket and was told they don’t carry blankets on domestic routs. The flight was on time and smooth!
