Our transit in Taipei was disappointing. The ground crew could not tell us where the lounge was located, so we wasted 15 minutes trying to find it. The airline has a great review, but our experience says otherwise.

Our transit in Taipei was disappointing. The ground crew could not tell us where the lounge was located, so we wasted 15 minutes trying to find it. The airline has a great review, but our experience says otherwise.

Greetings when you arrive on the plane and good bye when you leave. Very attentive flight attendants.

Serve me a meal, I fell asleep during the flight. So they passed me twice.

Seats are not table comfortable. Crew members are pretty good. Can be much better!!

Very pleasant overall, although the movie selection could have been better.

I usually have ear problems when planes land. But the landing was so smooth I didn’t even notice it landing! The service was excellent!

the aircraft was fine and new. The crews can have better training. Their operations are not as smooth as EVA's. They are VERY stingy with drinking water. Throughout the entire flight, no one offered me any water and snacks. I still prefer EVA after trying out Starlux initially with lots of excitement and expectations.

Everything was smooth and professional. They could improve the raw vegan meal with fresher offerings, but otherwise they are now my favorite way to fly to Asia.

Leg space is small. Need more room for long flight.

Leg space is too small. Need to increase space for long flight.

Great experience, comfort and food is delicious. Always great service and one time

The food from Los Angeles to Taipei made me throw up. The flight is also not comfort. But the staffs are very friendly and nice.

Flight staff were very courteous and efficient. Aircraft (seats, lavatories, etc) was kept clean and replenished

I have never heard of EVA air before but I am so happy my wife and I were able to flight on their planes twice. Everything on these flights just felt better than their competitors. As someone with longer legs any bit of extra leg spaces is appreciated. The different options for food and drinks were also a plus. They were extra careful to make sure my wife's eating restrictions were taken care for. They had a before take off and landing announcements on the built in tablets for each seat and it gave out information that was very helpful. Such as what and how to declare your items in the specific country you landed in, any odd items that may be illegal to bring it (and even the reasoning why) and any other information you might need to make your post flight experience better. Oh and the seats were more comfortable, had more ability to lean and the headrest was much better for flight sleeping. The only downside was there were "forced" ads on the tablet at take off for maybe 5-10 minutes but honestly, this flight was the cheapest option and had all the benefits listed above that is such an easy trade off. Im keeping an eye out for EVA air going forward.

Sub sandwhich for a snack through mid flight and giving a bottle water was a good idea

seats are pitched well. you don't feel too tight.

For the price, it was better than other airlines; quality of food and service was very good.

Movie selection was not as good as recent flights I've taken (EVA and other airlines).

Great but I am not sure why I was placed in zone 4 for boarding despite being an Infinity Member??? Can you explain online. Thanks

Clean plane, friendly crew, mostly on-time departure. Negativo since there were no snacks offered. Cold drinks only was fine due to turbulence, but nothing to eat? Really?

Every leg of the flight was late causing us to miss our flight to Okinawa and have to take the next flight out.

Wonderful I would recommend it to fly & ride with ANA.

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…

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

All the food seemed to have onions. I don't eat onions. Anyway, everything else was great. The biggest downside was the underpricer company that purchased the tickets from ANA. Underpricer never provided the United Airlines booking number. ANA was a code share and all our flights were on United. I finally was able get booking numbers from Ujuted on X. They saved me from the upsales underwriter tried to saddle my wife and me with.

Overall the experience was ok. My two complaints are that the food is absolutely disgusting. The movies in the flight to Japan were a completely different selection than the ones on the way back. So if you’re looking forward to watching a certain move on the way back, think again.

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

Hard to explain because we thought we were booking ANA airlines, not ANA operated via United, so we were disappointed, but for what it’s worth, everything went smooth and loved the movie selections. The food was okay, processed and full of preservatives, so vs what we were expecting with ANA it was different

My wife and I liked almost everything about ANA except for the economy seat space and the cold breakfast (croissant which seemed to just come out of the fridge)

The overall experience was ok, though there was certainly room for improvement. My husband was asked to check his carry-on bag at the gate due to claims that the flight was “full.” However, upon boarding, we observed ample overhead space and several empty rows of seats. This made the request appear unnecessary and caused some discomfort, particularly as he was the only passenger singled out for this procedure.

Food from Surabaya was below average but from Singapore is much better

The usual excellent experience with Singapore Airlines. The airplane was on time and actually early to Haneda Airport. The onboarding experience was pleasant with no delays, perhaps owing to the fact that the flight was not full. Nevertheless, the air crew were their usual outstanding standards in serving the passengers.

Good service and food. For buying items on flight should be preordered as they don’t keep much stock on board.

Excelent service and plenty of food and drinks during the flight. Flight crew very attentive to our needs. Leg room between rows are very disappointing.

Construction at PDX resulting in very lung walk from the rental car to the gate. SFO, extremely long walk between terminals to get to connecting Singapore airlines flight. My smart watch recorded a total of 3 miles.

So happy I flew with Singapore Airlines. The customer service is top notch. I am terrified of flying and the staff made me feel so at ease. Will only fly Singapore internationally moving forward.

It was very good experience on board to Sydney with SQ.

I very much liked and appreciated the service on board. The seating arrangement in Business feels uncomfortable. It's not made for tall people, in any case.

Great airline. Excellent service, good food & lots of TV movies/shows to choose from.

Everything was good except food , food choices was very less. Washrooms were closed.overall good experience.

Not a great experience. We paid for the upgrade for premium economy seats and seated ourselves in very comfortable seats. Someone came along with the same seat on their boarding pass. The aircraft had been changed and as a result we were booted out and sent further back to small uncomfortable seats. After complaining we were moved to emergency row seats, which gave us more leg room but the seats don’t recline. For people in our 70’s we found having to sit upright from California to NJ very uncomfortable. Not sure why they chose to move senior citizens instead of the two people that were allowed to take the more comfortable seats. Not happy.

I liked the choice of lemon ginger tea. I think stewardesses can be more considerate of older people needs.

I would have liked an opportunity to move to a different seat ( even would have checked in my hand luggage)as I had health issues where I didn't have to clamber over the passenger next to me to for toilet use/ movement [ She was a highly unpleasant neighbor to sit next to]. In addition, I found that my European phone plan had run out of data and so I was not receiving emails from yourselves on airport wifi to be able to check in online and verifications difficult as did not accept the ticket number I had. I asked for an extra blanket but was told there was none. Then I saw other passengers receiving them. I couldn't eat the food and asked for snacks : Stewardess said " on the way" but they did not bring. The best bit was the check in process in Lisbon. Very efficient. However, I did not understand why we had to collect our bags at Washington then go through customs again. It was not explained. I also with my leg and health issue had approximately mile walk to the gate ( which then changed) . There appeared to be no moving walkways or help provided.

More racist flight attandants maybe because i sm an attracticted darkskin latino man but once again bad flight attamdants they ignored me the whole flight even the woman sitting next to me notice how rude they were towards me i really never want to fly united or american airlines they alawsys have the rudesslt and racist flight attandants

It was great, I’m very grateful for the pilots and crew flight attendants for everything.

Everything was great. Only thing that could’ve made it better was buy on board options for hot food, but the snacks were decent. The flight attendants were great. I had no complaints. I was able to make it to my destination safely

We loved the United lounge near our gate and a rep named Aimee who was GREAT

Overall it was good. I missed my connection but I was put on another flight.

The attendant were friendly. I suggest you have a medical attendant on board every flight so that in case someone is sick , he/she will help them.

The woman gate agent in Phoenix was none too sympathetic about my check-in process as I am relatively new with using apps. I almost did not get on because she said I did not check-in. I thought I had via Kayak where I purchased a very expensive ticket. Lesson learned but to be told I may not get on as a matter of factly was difficult to hear.
