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.

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.

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.

JAL is quite nice in business class. Comfortable, spacious seats. Their entertainment, especially their film selection, isn’t that great though as their are not many new releases like some airlines offer their first and business class customers. . Food is excellent and the option to order on demand is always quite nice, which JAL offers. Flight attendants were very friendly and kind. Overall very good experience with JAL.

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.

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!

Marked by flight delays on all segments of the trip. Food in first class cabin was mediocre and overhead cabin storage was not adequate. Overall, the premium charge for first class cabin was poor and over hyped. This will be our last flight with UA.

Fantastic. Smooth boarding with an infant. Never experienced it with any other carriers.

The boarding process and flight were great. However, I waited about 40 minutes for my luggage. It did not come up on the designated belt. Instead, everyone’s bags were on a cart. Not sure what the issue was, but we were not informed until another passenger went looking for her bags and found them.

There were delays on both ends. It made it less than excellent. This plane was great though

AA1537 the AC was not working properly. It was very hot and uncomfortable.

Worst experience flying American Airlines. I fly with them often, so I was super disappointed in the service I received at gate 30 in LGA on May 24, mid-day. The flight was delayed twice. I was patiently waiting in the American Airlines lounge when I received the notice on my app that the plane was boarding 45 minutes before its newly re-scheduled take off of 4 pm (from the orginal 1:45 pm then 3:00 pm). It took me 5 min to travel from the lounge to the gate and when I arrived there at 3:20 flight gate attendant told me the flight had closed and that they announced for passengers multiple times. I showed them the notification on my app and they were really rude and unempathetic. The person who rescheduled my flight at customer service wasn't any happier but was at least helpful in getting me on the next flight.

Flight was 1/2 hour delayed leaving Phoenix. Otherwise it was an average flight. Flight crew on this trip was very nice.

Everything was great except for the wifi was junk. Crew was super friendly and helpful

Was lucky to have a employee at the AA checkin counter that had compassion and understood they ordeal that we went through with our original flight being diverted, needing to stay in the aircraft and then flying to the original destination; adding hours to the trip and forcing us to miss our connection and our rebooked connection. She was able to get up on standby on the highest priority on the next flight to the closest airport we need to be at and it all worked out despite being many hours late.

We were redirected to a near by city due to weather and had to stay in the aircraft before flying to the original destination's airport. The whole delay added 3+ hours and were were not offered any snacks or water.

I wish that we wouldn't have to go through TSA again on connecting flights.

Priority baggage, golf bag lost causing me to miss function the next day. Baggage in general in Charlotte has been a mess lately.
