GordonFlew with United Airlines-Apr 2024
Check your all or most of your luggage if you can. Take a small light carry for your must have items with you such as snacks, book and electronics on hand accessible during the flight.
SoukindaFlew with Singapore Airlines-Feb 2024
Bring a sweater, a mask and wear socks. Although they provided a blanket, it’s very chilly on a long flight. I caught a nasty cold from the flight and wasn’t masked up. Other than that our flight was great and comfortable.

If you are flying with an elderly parent that needs to be near restroom, have an agent place you in the back. They will take care of you.

Eva air was fine - Trip.com via KAYAK sold my family access to a “VIP” lounge fo a layover in Taipei… i’m please look at my pictures. It was a scam, Trip.com knows it and they are perpetrating a fraud through your web site.

Eva air was fine - Trip.com via KAYAK sold my family access to a “VIP” lounge fo a layover in Taipei… i’m please look at my pictures. It was a scam, Trip.com knows it and they are perpetrating a fraud through your web site.

Crew are excellent. Food was good generally. Seats are small and there isn’t much leg room. Overhead bins are very small.

More seat space More bathrooms Charging outlets Plane was old

It was a pleasure to fly with EVA airlines from Taipei to San Francisco.

I love EVA airline, but the KAYAK website for not in emergency, urgency and personal issues. For instance, on January 5/2026 with already booked the flight, I have a 15 hours of delay between airport when booked before as my choice. But if I want to go back home (U.S) early, then I have to contact the KAYAK office at I was in other country without phone service and nothing that EVA can do for me. Even I offered to pay more to change from another flight to go to the U.S early, not wasting at15 hours of delay, but EVA could not help me until I call KAYAK at an Island of nation. No office of KAYAK from any nation and times of difference in the world. However, everything and everyone is the best. Therefore, please KAYAK making much more easy for both the airline and passenger in some issues at the middle of nowhere in some country when no need to call KAYAK for some emergency, urgency, sick, etc or personal reference. Please, please, please no need to call KAYAK office for any changes of flights from urgency or private.

My seat arrangement was good with Eva Air. The toilet sanitary was good ( hand wash, face moist spraying, fresh air spray, hair moisturizer). But the Asian movie selection was not great at all.

Don’t preorder the diabetic meal if you don’t have to. Whoever creates those meals thinks everyone loves fish, and hates seasoning. In a world where we can find diabetic friendly candy and low card bread, it’s surprising that places are still serving flavorless gelatin and rice cakes. Boarding in Taipei was chaos. They tried to form a line but didn’t manage it. So once the gate was opened, the line didn’t matter and everyone just mobbed to the front.

Flight was canceled was only given only a 8 hour lead time. Had to fight to be put on another airline (United Airlines) that was leaving earlier then the one EVA and rescheduled.

EVA! What is going on with your food!?!? Pre pandemic I used to go to Taiwan at least twice a year and always flew EVA — the food was consistently tasty for airplane food. Post pandemic, it’s not great at all. Step it up!

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

Very poor experience and will never travel with JAL again. With Business class ticket i was told that there is no veg option for the 1st leg of my journey from Delhi to Tokyo while served horrible plant based meat on the second leg of journey even though i selected Vegetarian meals. Also entertainment system is worse than domestic flight with hardly any Hollywood movies and no hindi movies at all

After boarding it was fine. Premium economy was not available for one long leg. Economy was very uncomfortable. They need to fix these issues. Planes are old. It gets more and more dangerous due to fatigue of plane parts. They need to upgrade before something goes wrong with the plane. Hazardous. Hari S Doss

The crew was attentive and provided everything I needed. The business class food was excellent.

Fantastic flight company. A higher standard than any American airline company for sure.

Issue 1: We had a 2 hour delay to repair a windshield wiper, during which we sat on board on the runway. Issue 2: it was VERY HOT in the cabin for most of the flight, we were sweating. We asked to make it cooler. They didn’t succeed in doing so. Other than that, it was great. Fantastic food, and extremely pleasant, accommodating flight crew.

Flight from New Delhi to Tokyo was mediocre. The seats were not of business class as we are used to. They were not wide enough. On the other hand the seats on the flight from Tokyo to San Francisco were excellent every thing were great except the food. Tokyo business lounge was excellent. The whole experience was great except the food on the plane. Will still fly JAL.

Difficult to access advanced check-in online. No way to understand why it wouldn’t work. Call center not answering. Email for answers took days to respond, Kind service at the airport and on the flight made up for disappointing service before flight.

Courteous and helpful employees. Comfortable seats and temperature of aircraft . Did not need squid in my salad but glad to have the menu information advising me of what it was

Good legroom. Front seatback has best compartmentalization, netted pockets on sides of tv monitor for eyeglasses, water bottles etc. For Economy, best food across the Pacific. JAL doesn't skimp on quality to squeeze out more profit. No prepackaged items in plastic wrap. Cocktail service first with nibbles, Wine in your own 2 glass bottle. Later dinner service, more wine! Lastly, breakfast-lunch, more wine if you choose. Lastly, the friendliest most smiling crew across the Pacific.

Will definitely try to book with them again next time. FAs are very helpful and nice, bathroom always clean & flight was comfortable.

The quality and the quantity of food was terrible. I was starving to death at the end of the flight. Used serve 3 meals long time ago, now reduced to 2 meals during the 17 hours flight. Never offered wine or tea to us. We have to ask . Extremely hard to get the attention of the flight attendants. They intentionally ignore us to minimize the service. Bathrooms were dirty

Never book through Kayak. They can offload booking to third parties that are completely horrible.

Crew is excellent Wifi needs to be improved in order to connect to the internet.

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.

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

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.

They are great with every aspect of customer service. Helped my elderly father and aided him with using the restroom.

Excellent customer service from pre boarding to the end. Really enjoyed my flight. Very helpful crews during flight as well. Will definitely flight with Singapore airlines again.

Food quality and serving frequency was poor. Travel kit was not provided. Flight was very bumpy. Overall, not a good experience.

They overbooked the flight and reassigned my seat. To add insult they lied that my assigned seat was broken and promptly gave it to someone else

Jain veg meal I opted was super in taste but there was no sweet/desserts with it. I was a big missing in the meal...Please add some sweets to end the meal with 😊

I’ve flown 2 better Asian airlines in the past year.

Seat is too small. Food selection is limited and often ran out of selectable item.

The worst experience ever! Lots of flight delays and rerouting that ended up doubling the total time. . I had to recheck my luggage because I was rerouted to Tokyo and ended up on ANA flight. I missed connecting flight twice because of the delay at Cathy Pacific. Additional stop added, rerouted to a different country for connecting flight and ended up in long waits and delays.

My only suggestion is a way to not be woken up for food. … like maybe something you can place on you if you’d prefer to miss food than be woken up

I wish there were more bathrooms available on these larger carriers.

Not much of anything could have been done better unless I had a first class ticket. I was literally 15 hours with an airline in the economy class. Very professional friendly and attentive crew. Good airline food, clean cabin, seating area and bathrooms. I've been 4 times back-and-forth with Cathay Pacific, and I would not choose another airline for this trip. Five out of five stars.

Special request meals are really below average. Vegetarian options are very limited if you didn't prebook.

Horrible. No good food. Baggage missed to onboard and came after a day. No support to compensate the delay. Customer care cannot see the status of the complaint. No reply of the email.

The pre-order only approach for fresh food is really challenging

the seat has a problem. the back had a hole.

The entire experience convinced my wife, Cathy, and me that traveling Polaris on United is the only way we’ll fly in the future. From check-in and baggage drop to the end of the 12-hour flight, the customer service was exceptional, with numerous staff members exemplifying the very best in care. On board, Andre, our primary crew chief, was sincerely friendly, a consummate professional, and, along with Freddy, one of his team members, truly among the best of the best. The captain even came through the cabin to chat with passengers—a wonderful personal touch, especially on such a long journey.

The SFO lounge closes at 12 midnight. My flight took off at 2AM

Flight be on time would be a good start. Then train your flight attendants to be attentive and friendly. This time they completely forgot my row for the measly snack! United, do better!

We boarded the plane and were about to take off when we were notified that the tires had to be checked. Upon inspection, they were found to need replacement, so the entire plane had to be deboarded. After we exited the plane, United staff forced us to stay in the gate area by posting "Do Not Exit" signs on the doors connecting the gate area to the terminal. Many of us had already rebooked our flights and had no checked bags, but they told us we could not leave. This seemed inappropriate to hold people under false pretenses. When the agent told us we could leave, I asked them to please take down the "Do Not Exit" signs, as they were misleading. The agent refused, and I told them that it didn't feel right to hold people like that.

Staff was generally seeming stressed out and was a bit rude and slow. Plane left late. Pilot was very well-spoken.

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.

Meals were adequate but could be better. Lots of movies, podcasts, tv shows. We really enjoyed using our personal headsets highly recommended. 15 hrs flight great to travel at night.

Customer service - staff was effective in getting my trip rescheduled
