They broke the contents of my carry on that was forced to be checked in.

They broke the contents of my carry on that was forced to be checked in.

They forced me to check a bag. When Kayak sold me these tickets I was not informed of carry on baggage weight limits.

Great food on both legs and fast customer service from the stewardesses....

Very nice, I feel I got good value for the price.

Certain flight crew member were rude and short with me when I asked questions.

everything was so good! Especially Food. It was the best I've ever had! However,I requested to add mileage point to Star alliance group ANA; it hasn't been added yet.... 😞

I appreciate the email reminders for online check-in which made my entry to the lines less stressful. The flight was on schedule and on time. The baording staff were proactively helpful and approachable. The airplane inflight food, entertainment and comfies as well as provisions are excellent even in the economy seating. The airline transfer was smooth and easy! Luggage safe and intact! Thank you EVA airline for making my trip a reliable safe and comfortable experience.

On time service. Seat comfort and the crew service very good .

• Crew obviously hate their job • We were placed in the very back of the airplane even though we checked in 4+hrs before our flight • We were given food but since we were in the back of the plane, we were rushed to throw it away. • This was the most unorganized boarding experience. They just called “Group 1” to board and after that, it was chaos. Everyone was confused and they only spoke in Chinese.

Eva air is a good airline. The seats on the way to Taipei could have certainly been more comfortable, but all in all it was a pretty good experience.

It was good overall. What I liked most was the restrooms. Compared to other airlines, the restrooms seem larger and look clean. The seats also look clean. The attendants are nice, except one time during the flight. I was sitting on aisle and a man sitting window. He asked an attendant for a snack. She told him to go ahead and get some snack from the section with food storage (I am not sure how it is called). So, I had to get up to let him get out from his seat. Why she did not bring him some snacks so that I would not have to move, I do not know... I was kind of surprised how inconsiderate the attendant was.

It was okay, short flight so nothing much to comment.

Japan Airlines was excellent as usual once on the plane. Cabin crew was wonderful as usual. Boarding was solid on the Honolulu leg. For Thai Airways the boarding was less organized. I was in an earlier group but they weren’t clear with the numbers or instructions. Flight crew from Japan to Thailand was very good.

This flight was leg 2 of 2 leg journey. The staff at baggage re-drop in Tokyo were fabulous. Once at gate when time to board, had to take standing room bus to the tarmac to board. Did not like getting out to plane and having to wait 5 minutes until they opened bus door.

Seats in "Premium Economy" were noticeably more comfortable than those in "Economy" and worth the price. My only reservation is that the foot rest did not go higher up. If it did, it would have made the seat much more comfortable.

Attentiveness by crew was very good. The seats were uncomfortable seemingly too hard with inefficient cushioning. This was verified with my traveling companions. Also the incline button was inoperable.

I purchased the ticket online and went to do online check in amd the app wouldnt let me. I went to the airline desk and they couldnt confirm my ticket in their system. I ended up having to buy a ticket from the airline directly and paying twice for the same flight. The app wouldnt lwt me check in the kayak purchased ticket until after my flight was taken off.

Particularly meals were great. Service’s were excellent as usual. .

Great easy And smooth check in boarding and flight. Great experience. The allergen free meal was good because I could eat, but flavor and texture left a bit to be desired.

Consider adding “N/A” to some review options. This flight had no food or entertainment.

The food was terrible and totally inedible. If you are flying with ANA/United bring your own food it was a long flight to be hingry

Delays, plane transfer due to malfunction, no entertainment, limited beverage service.

Cabin Crew was excellent. They took care of everything requested. Flight was good

The ROOM was great. We would love to have it on all of our flights. LOL

Flight was good and comfortable, even for long haul economy. No complaints.

Everything was good may improve some alcohol drinks and amenities during fly

Due to turbulence there was no inflight service, which is very understandable, The flight is very short, and safety is more important. There was a bit of a delay with take off, but was to be expected with the rain.

Wonderfully pleasant experience. Good meal and beverage selections. Professional air staff.

Wonderful. I love ANA airlines. It's the best so far. My first pick when I travel now.

Loved that leg room was great for economy, and food was definitely better than other American airlines, great selection of movies. My mom is happy.

Really impressed with the Airline and much with the Crew. The crew was amazingggg, changed seats very easily, provided a lot of snacks on demand, the plane is nice and clean, the menu is well presented; unfortunately, the food is not fantastic, but it's not bad either but nothing to rave about. I am still rating it as excellent because I loved everything else; food improvement will be great!

My flight was delayed by 8 hours I arrived at airport 4hrs earlier but to see if they can reroute me to get my connecting flt to Hong Kong. They auto rebooked my flt. With no chance. Which I missed this entire reservation through kayak. My next flt they got me on was at 6 am. Misses an entire day of my trip abroad all my accommodations seat assignments were missed and missed adding my TSA precheck to my ticket as well as my vegan meal request so I didnt have meals on any of the flight....so not a comfortable experience. Please help me with accommodations upon my return.

Good service and food. However, we paid over $400 for aisle seats for my disabled husband and me, and we were given window and middle seats. This was dangerous for our health condition on such a long flight. We needed to stand up and walk around frequently, but we were stuck in our seats. Please give us a refund of our seat payment since you chose not to honor our request.

Great entertainment system, the seat is a bit old style needs refurbishment

Boarding at the airport was not well managed. Otherwise, had a good flight sitting in the first row (which I paid for). Crew was pretty friendly, and flight was smooth.

Everything was fine and I have no complaints or things to note.

The economy seats are much indeed roomier. Meals needs improvement.

Food was hood for airline food with good poftion and variety in meals. Frequency of beverage service was very low and amount of soda with meals was inadequate.

From Chicago to Hong Kong was great., but from Hong Kong to manila we had hard time looking for the gate of our connecting flight. There wasn’t hardly any sign.

The flight crew was exceptionally good. Personal needs were well met. The food choices were very nice.

The code sharing reservation with United was messed up requiring extra trip to airport to fix. Air Canada customer service 2.5 hours on hold and resolved nothing.

I'm 6'8" (2.03m) so more legroom would alwqys be appreciated, especially on long international flights. The food choices were underwhelming.

Didn’t make it on the flight. Delayed then had to be rebooked, which in turn had me waiting at the airport for another 8 hours before next flight

the check-in lady at ORD was extremely rude and unprofessional. very disappointed as it was supposed to be a celebration for my wife's birthday and it really put a damper on things. if i wanted to be treated like trash, i would have flown Economy! (as opposed to business class)

Short flight. Everything was fine except the flight was delayed twice for a total of an hour.

There labor disputes cancelled my flight less than 24 hours before my boarding time but there customer service/website was easy enough to navigate and they rebooked me for no upcharge.

Very bad, flight was cancelled due to strike and staff was unable to rebook us

Flight was delayed by 1.5hrs. Once inside, people had their small handbags on the storage. The crew (male guy) was not helpful in making some space in the storage. Instead, he asked few bags to be checked-in and it was not a great experience. No attempt to help but just followed the things with a straight face. People had their literally small bags and he wouldnt not move from one storage to another even if there was space and would not let us do i as well. Once flight was on, they ran out of Orange juice, really running out of orange juice when the temp were 32.degrees outside. didnt made the sense. Onasking for a extra snack, he made a face as if he was giving me out of his pocket. if the flight was delayed, there could have an attempt to provide something extra incase people did asked.

Abandoned me in hallway in a wheelchair… which I asked for because I sprained my back. After waiting in the hallway, I decided to walk the rest of the way since someone respecting me up.. My experience with the united was totally the opposite. Wheelchair access, propped swift and save me a lot of grief. Air Canada totally disorganized.

Terrible confusion btw air Canada and United. Wasn’t able to change ticket because I had purchased on kayak. Rethinking booking tickets on this site, and will try to avoid United and aircanada going forward.
