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

Older 777 - showing lots of wear - Premium econo seats that are difficult to recline and worn springs to they don't return to takeoff position without standing and pulling them forward

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

I booked a ANA flight, this was just a regular United flight — as always very bad, dirty, rude service, quite frankly really embarrassing to be flying with this after spending time in Japan.

Staff and crew are wonderful, professional and courteous. Meal is delicious and snacks can be improved. Entertainment needs improvement, pls update selections of movies. I appreciate that our flight was on time

I flew economy class so of course it’s not as roomy as business and first class. But overall it was ok and the seat had an interesting way to recline — the seat itself extended forward instead of the backrest. This way the person sitting behind me would not lose space by my reclining—excellent concept. I wish all airlines used these seats.

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

For the price of a seat that is obviously crammed together so as to get many more people onboard and combined with the long flight duration, Free WiFi should be an automatic “Thank You for Flying with Us!” To charge an additional fee when so many other businesses offers it is a bit “cheap” on the airline’s part.

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.

Food was high quality. Crew was extremely professional, polite, attentive. Flights were on time. Plane had good media tech.

The hygiene of the bathrooms were terrible. Urine smells leaked out into the cabin and the seats were really tight, even for a petite woman like myself. Flight attendants did not go through the cabin enough to offer refreshments.

I was expecting that movie selection and food would have been better. Everything else was great.

The type of the food requested (Asian vegetarian) was not properly met with. They have very limited snack items that may compensate for the main meals.

The quality of the food is pretty good. Thank you, EVA Air.

A wonderful new plane. Great menu. Professional service. You and your wife were completely satisfied.

Pleasant crew. Very long flight, a bit uncomfortable at times being seated, but not too bad.

No ice for the drinks. Only gave a half a cup of your beverage. Not enough water. I got very dehydrated.

Eva is one of the top airlines in Asia... but often are over priced. Finally found a reasonable rate.

My original flight was rescheduled & EVA did a good job rescheduling my flight & connecting flight.

Polite hard working crew. No complaints really. Meals were not to my liking.

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.

Very pleasant, look forward to flying with JAL again if the price is right.

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.

Great service but food taste and options have gone down a few notches.

This airlines is always my favorite. Very consistent customer service and food is good. My last flight with them, I had no idea we landed because it was just that smooth of a land.

At least it was not very cold inside the plane. I noticed there was now a bidet in the bathroom and that’s good! I didn’t like the window seat. Flight was smooth except for 1 turbulence. Plane was on time. Thanks. Food was not that great. Miso and green tea were good! As usual movies were old and there were no changes.

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

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 .

JAL is a flawless airlines. Perfect customer service. On-time boarding, clean airlines, and incomparable in-flight dining.

It was one of the best experiences. The staff were amazing. JAL is my second favorite Asian Carrier I have flown on. Korean Air was my first. Thank you JAL for bringing me home safely and for such an amazing staff and service.

My experience with Scoot is very good. Will have no issue flying with Scoot again.

My overall experience with Singapore Airlines is great. Will definitely fly Singapore airline again.

Good flight. Fiod was ready a bit late hence a hurry to finish before landing. Excellent crew and service

Great to have actual hot tastey meal on a flight. Well done

Cabin Crew always friendly and helpful. Seating cramped - foul smelling from toilets, high risk of disease. Guard personal property such as expensive sunglasses Coffee always awful and cold Meal trays toddler sized Not worth the extra cost to fly SQ - use a budget airline, same if not better experience

When boarding, after business class should be premium economy, but economy class already lined-up at the gate blocking premium economy to board. Singapore airline crew should done a better job to organize this chaos :( Thank you.

It seems paying premium economy does not make difference with economy. No priority boarding, not worthy paying extra$$$ for premium economy.

A pc of cake or biscuit at least. The airport was like a maze need to take another bus to the main terminal to immigration.

Flying with Singapore airlines is always excelllent - the crew are lovely and the food too is great. It’s my number 1 airline

They were able to assist my elderly father and myself after not being able to check in to scoot. The counter service was phenomenal. They did what they could to get us on the next plane so we could catch our Connecting flight. Scoot closed early on us so we ended up missing our flight.

Flight was late due to mechanical, had to spend night in hotel. Experience disembarking plane was poor, United did little for passengers except what they were required to do by law.

If the flight is delayed, get the delay timing right and don’t have people standing in line ready to board for almost 2 hours because you keep pushing it back. Also, don’t have your flight crew say they are sorry when they clearly don’t care, make no efforts to speed up anything and then turn around and are rude to customers when they don’t “move fast enough” to put up tray tables and seat backs.

I was not expecting much as i was not in a premium cabin. I was pleasantly surprised that the seat in economy plus was spacious and food was ample. Party of 5 with 2 parents and 3 kids.

Outstanding in all respects. Early boarding left early arrived early. We were in business class, so was perfectly fine.

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

Dinner was okay but the breakfast was not eatable on the flight San Francisco to Zurich.

I really do not like the basic in basic economy.

There was no screens on board AND the WiFi didn’t work. My seat was broken and couldn’t recline so I couldn’t even sleep. The flight attendants didn’t offer anything to make it more comfortable. It was such an old cramped plane, when the person in front of me reclined I couldn’t even open my tray table. All the United ads talk about guaranteeing everyone gets a screen!

The Wi-Fi was unavailable on this flight for some reason.

On time take off…US cabins look tired and need of refresh!
