The food was the only thing that could have made the experience even better. Everything was stellar but the food. The staff was superb. I’ve been flying with ANA for years as my go-to and I think I may have found my new favorite. 😍

The food was the only thing that could have made the experience even better. Everything was stellar but the food. The staff was superb. I’ve been flying with ANA for years as my go-to and I think I may have found my new favorite. 😍

Short lay over. Seat assignment was terrible. Was traveling as a family and end up being seated separately. Will not use underpricer ever again.

Unable to set seat assignment. Got a call from presumably “China airlines representative” but was asking for an exorbitant amount for the seat assignment. Was traveling as a family end up being assigned to different seats as a result. Will never use underpricer again.

Not many selections for entertainment. Bulk head seats are no longer available with out fee at the counter. That’s pretty lame.

All of the staff were very helpful, polite I was very satisfied with China Airlines The food was normal for airlines but I’m sure they could do better

Staff very friendly and helpful Everything was clean and most important on time Unfortunately let down by the quality of the food Would be very happy to use them again

The flight who provided services on my row had some not-nice attitude and not smiling at all.

Very good , the weather was terrible, but i admired the professionality and politeness and care from the crew, and the excellent contition of the plane

Comfort was left wanting due to such a long flight, made the wife and I wish we could upgrade the seats to Business class or First Class, but did not have that option. Food was good but had very limited options and I have a dietary restriction which was difficult for the staff to accommodate since everything provided came with cheese on it. (Cheese could potentially kill me) Did not have an option to inform the staff until we were already in the air about the restriction and was not provided another option before flight departed.

Decent flight, staff was very good, especially with the turbulence during the flight due to weather. Comfort was about par with other airlines but since it was a quick flight, was not much of an issue for us.

The flight was canceled two hours before departure, it took over five hours to rebook us on another flight.

Rough day of travel all the way around. Wrong info given to us multiple times and mistakes in their booking making our trip 10 hours longer than planned. I’m bummed because I fly Delta all the time and love them. Mistakes happen. Just bummed that this was a rare trip our whole family was traveling together.

Meh. A late flight meant I missed my connections, and a 2pm LAX arrival turned into gettin in after midnight.

It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Your crew could maybe answer the call bell at least one of the times I pressed it. I pressed it first time with 2.5 hours left in our flight bc my partner was hungry and wanted a sandwich. We finally got the sandwich with 40 mins left in the flight.

The Flight crew didn’t serve us until about 1.5 hours into the flight because of turbulence but after it ended it was fine to move around. They served us water only and snacks and then NEVER, NOT ONE TIME came through to collect trash until right before landing about 1.5 hours later. There was absolutely no need for that. They crew was just standing around talking and visiting with each other and really never tried to see if we might want something besides water or even try to come pick up trash. This is VERY unusual for a Delta flight but it was not what I would have expected for a 4 hour flight.

There was a loud squeaky sound the whole time we were flying.

Had a broken tray in business class. Crew just shrugged it off.

I didn’t like that I could not select my seat and was assigned a seat when I checked in at LAX

Transferring from International to Domestic/Mainland was a PITA; Hawaiian could not handle the rebooking of bags quickly after customs, etc. Eventually took it over to Terminal One where they were able to do it quickly. The "snack" or whatever on the flight was - Pepperoni Bagel - and for anyone who doesn't eat Pepperoni, tough luck. I guess they consider it too difficult to have Plain Bagel for anyone else. We don't count; they don't want our business. Then I got to SJC and found they had smashed one corner of my (brand new) suitcase such that it wouldn't roll because that corner collapses inward. They explain to me was SOL, as "they can do anything to the outside and they're not responsible". So if you fly Hawaiian Air, expect to have to replace luggage routinely. They don't want my business, they won't get my business.

Awful kids kicking seats and screaming the whole flight and parents didn’t say a damn thing!

Kayak reserved return seating for me but did not book it. I paid $115 extra and my seat was not reserved.

seat cushions could be replaced. the foam bottoms out (I am 170 lb man). more lower back support would help. I tend not to recline the seat, so it would help if the seats were very slightly inclined; makes it hard to sleep without toppling forwards.

Great flight. Had free internet for whole flight. Made it so much more enjoyable

The jet bridge electricity was out. We were boarding in the dark. No air-conditioning and it was extremely hot. Every person that came out of that jet bridge into the aircraft was profusely sweating. Truthfully, sitting in first class, it was no Hawaiian hospitality. Just a bunch of senior flight attendants are doing their routine over and over.

The in flight speakers little touches of humor were entertaining.

The flight left and arrived on time. the only food offered on the 5+ hour flight was a cheese sandwich. Unlike Alaska Airlines there was no information on the website regarding food at all or any option to purchasse in advance. Otherwise, it was an excellent flight.

We were not given the seats we reserved. But helpful attendant at gate gave us very nice seats.

The flight was very smooth and comfortable. The entire flight crew was very professional and provided excellent service. Thank you.

loved the bulkhead seats with all the extra leg room! The initial dinner was excellent unfortunately the last meal was unsatisfactory. Our salad was partially frozen and the pizza roll was 90% dough. My only complaint

See my previous comments. I was probably booked in business but was moved to economy

Boarding was efficient. Crew was not pleasant and skipped me during a round of beverage service. Older plane with no seat back screens and I couldn’t connect to wifi or their entertainment offerings.

My flight was delayed for a whole day, so I lost a day of my vacation.

I was refused to used the toilet closes to my seat and had to go to the back of the plane .. it was difficult for me I’m a wheelchair customer

No entertainment system or wifi on a 12 hour flight. They failed to include GF meals And snacks as requested on my ticket so I had very little available to eat. Crew seemed indecisive.

Ability to watch movies.No earbud sound system.Marginal beverage service.Unexplained late take off resulting in VERY tight connection in LA which proved maximally stressful.

Great service; lots of water offered, frequent trash cleanup; tasty food

United Airlines was fantastic, however, UnderPricer was a nightmare. I got to the airport 4 hours before my flight. We are moving to New Zealand so had quite a bit of baggage (16 checked items) and so wanted to have plenty of time to get everything taken care of properly. When I went to check in they (United) could only find a ticket for me. The 5 tickets for my children were never officially ticketed. I called Underpricer and they told me it was United's fault and United told me that Underpricer just needs to reissue the tickets, but they refused to. I asked the Underpricer agent to transfer me to his supervisor as I was not getting the help I needed. He told me the supervisor was busy but that he would call me back in 30 minutes. 30 minutes came and went with no phone call. After an hour I called Underpricer back but they would not let me talk to the person I had talked to before, just told me that he was talking with the supervisor and technical support. I called again an hour later, was told the same thing. I tried again later, with only about 30 minutes until my flight was scheduled to leave (meaning I had been at the airport for more than 3 hours with my 5 children trying to get ticketed and board the flight). Also, my husband had moved to New Zealand 3 months prior, I haven't seen him in 3 months, my children hadn't seen their dad in 3 months, we were all extremely eager to get on that flight and get to New Zealand. The situation with the tickets did not get resolved until after it was too late to check our luggage and board our flight. We were devastated. My 11 year old son was in tears at not being able to be on his way to see his dad. Thankfully we were rebooked for the next evening, but that night it felt devastating. We'd been at the airport for 4 hours waiting. My in-laws waited with me and then helped me reload all our baggage and took us home to stay with them for the night. On the newly booked flights we could not sit together - my children were spread throughout the plane. So, even though I had paid extra to select our seats after buying my seats from Underpricer only two of us were able to sit together (thankful that my 11 year old wasn't all by himself, but not happy that my 14 & 16 year old daughters were seated by strangers). I really feel that Underpricer should refund me what I paid for the seating ($120 USD). It was a very frustrating situation and I plan on never using Kayak or Underpricer ever again.
