Cabin crew were excellent in taking care of my mom as she boarded the aircraft from her wheelchair. Did not care much for the food served.

Cabin crew were excellent in taking care of my mom as she boarded the aircraft from her wheelchair. Did not care much for the food served.

I stopped flying with United back in the nineties. Today's experience reminded me of why.

Great airline all together - triple 7 for a short flight was a plus - lots of room

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

Seat width can be a bit wider. not nice that they charge extra for the window seats. online check in can be greatly improved. in other words, their online interface is bad.

Seat width can be a bit wider. not nice that they charge extra for the window seats.

Seats were comfortable with excellent legroom. Meals were also quite good. The cabin crew were excellent and very helpful. The check-in experience was also very smooth.

Seats had more space than expected. No recline, that is good.

Everything was excellent except for the hot cabin during the two trips. Why would you keep the cabins cool hot?

The ehole fliht went smoothly. No delays. Bur the food was not good.

Allow gold card holders (Group 1) to board with their guest like other One World carriers do

Checked baggage process is confusing and time consuming especially when checking oversized bags. Very slow agents didn't help.

Food was great, Entertainment was bad, movies were not current and just did not have good variety. Granted I was tired so cranky might have played into my evaluation. Overall based on cost I definitely would fly them again. I am a million mile flyer on another airline, the service on JAL really beats all airlines.

The team members are extremely attentive to make sure you have the best experience.

Was in premium economy. It is slightly better than economy, but the way the seat reclines actually makes it harder to sit (the seat slides forward and the foot rest comes up - you can lie fairly well reclined but you’ll have to sit cross legged because there is no place for your legs to stretch out. Food is basic economy. Service was great. All in all good, but may make more sense to pay more for business or save a bit and just sit in economy.

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.

There were agents in Haneda that assisted us with our short layover, they actually escorted us from plane to gate! Amazing service and kindness maybe eclipsed other minor issues. I had difficulty with on line check-in and because I wasn’t able to do it we had to go to the airport without advance checking. They split my friend and I in seating arrangement twice. Food quality and coordination of entrees and side dishes was a little off. Seat comfort led me to posture where I had to lean backwards a little unnaturally, from an upright position

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.

A great flight experience - great seats, lots of ROOM for legs & in the aisle. Great attendants! My flight cost me the same as ZipAir, the website was WAY less confusing & wonky - this will be my 1st choice for my next Japan trip. Very pleased / well cared for.

Plenty of room for me and the cat in Premium Economy. Seat was comfortable. Boarding was a breeze. The lady at the special check-in desk was great, super helpful and professional.

Smooth flight. As always dinner could have been more generous. Breakfast was great.

AWFUL. I have had the experience of traveling with many airlines across the world, and hands down United Airlines is the worst. Not one flight was on time, and I don’t think I met one crew member or staff member who wasn’t rude.

Old and out of date plane, it seem like every time I fly with united there’s and issue. We were delayed,

We took off an hour late due to arrival airport not having enough gates. That was followed by 1:30 wait to get our bags delivered for the entire flight.

For an 8.5 hour flight the service on board lacked a bit. Service start was slow, the food was worse than usual and they skipped the snack they were supposed to deliver before landing.

Wish movie and music choices changed more often. Mostly same from a month or two ago when I last flew.

It was good. Just that the seats could not be reclined. The people behind were not ready to let the chairs be reclined

Checkin was painful and slow! Lady didn’t seem to know what was going on and couldn’t explain the delay. Seemed ahe couldnt see the computer scree and we couldn’t hear her talk through her mask.

Plane left & arrived early- 5 Crew great. Wi fi - paid for 2, only 1 worked - so so. Waste of $. Coolie was good

Easy to board and fly, no frills. Yummy ramen on board.

It was for the most part a 10/10 they said they had entertainment options but all they had was old movies for streaming from the mid 2010’s so like 10 years ago

all good for a very budget flight - well priced and excellent service. Will fly again

Couple of the crew members were really nice and the rest are really rude and didn't help when we needed help, food was not worth it at all and most importantly there's no even entertainment system other than a very interruptive and slow internet and some movies.

I appreciate the economy price of the tickets. The long flight made the comfort level on the lower average side. Wi-Fi connection was not consistent but working. Overall, I would fly again with zip air but next time get the flat, premium seats with the amount of money I would save otherwise.

Comfortable seats and lucky no one was in middle seat. No water on the plane. Plane was on time and staff was fast.

You get what you pay for and nothing more. Wanted a cheap flight and that’s exactly what I got, though it’s human nature to wanting to feel like you got a good deal as well. There was none of that here. I was cheap and they were too. Got to my destination safely and that’s all that really matters.

Nice service. I wish it could provide hot water on the flight.

internet didn't work. No offer of drinks or snacks.

Flight was seamless. Free wifi helped pass the time. Food was okay, just make sure you pre order or pick something up from the airport

Amazingly comfy flight - I had upgraded for a reasonable price and it was worth it. The food also was good.

Had to wait on pilot and crew to depart and had to wait to arrive at the gate because they only had 2 crews working. Delays, delays....Planes just keep getting smaller and tighter and they nickle and dime for everything. When will an airline actually wake up and make flying more enjoyable?

I paid for what I got which was cheap, I brought my own entertainment. I knew what to expect, so I could be prepared. If you’re flying economy, check in early like me. I have no problems with my flight, was on time, staff were friendly, and overall good experience.

DO NOT BOOK THROUGH AMERICAN AIRLINES IF YOU HAVE ANY ADDITIONAL NEEDS. Great flight, crew etc. it wasn’t full so had space to stretch out Only downside was there was no GF option for my partner. We booked through American and it was a Qantas flight so despite contacting both airlines to confirm, she didn’t have a gluten free meal for the 16 hour flight (nor the flight in the other direction). The flight attendants did their best to accommodate but it was not super substantial.

After several delays and being rebooked onto a layer flight, I had to speak to three AA agents for baggage claim to get an attendant. All were in foul mode and reluctant to assist or offer any assistance.

Multiple maintenance delays and the missed and rebooked connection changed gates at least 6 times including one which had us walking 20 minutes to another terminal and then back again. Seated our family of three in different middle seats throughout the plane and then there was an empty seat next to me. Very long travel day which I would have never agreed to if I knew the itinerary would be changed at 5 am, 2 hours before takeoff.

It was as expected for such a short flight. No complaints

It was nice being on a flight that had working wifi. The boarding was quick - why don’t all airlines have small boarding groups window to aisle? Makes so much sense!!! I was disappointed to be the first person stopped to have to gate check my carryon. Especially when there was plenty of overhead space at the back! But I get it…keeps it moving. Crew was nice.

The flight encountered a delay exceeding 4 hours. The food voucher issued was valued at $12, insufficient to cover our meal expenses. Consequently, I was unable to take my medication, leading to a drop in blood sugar levels and exacerbating my anxiety.

Crazy seating issues. We got seated far apart. Offered middle seats at a premium rate. Why is a middle seat now the expensive seat? Baffling.
