The space for the seats i like it. Its not too close like other air line. The food is ok and also the staff. I'm waiting for my flight rewards point because until now i didn't recieved it.

Flying with ANA is always a breeze. Seats are very comfortable.

The staff, ground and air, at ANA was very helpful and friendly during check in, boarding and during the flight. This is the reason why I always fly ANA whenever I go to Manila. The food was not the best but the flight crew more than makes up for the shortfall.

For the price of a seat that is obviously crammed together so as to get many more people onboard and combined with the long flight duration, Free WiFi should be an automatic “Thank You for Flying with Us!” To charge an additional fee when so many other businesses offers it is a bit “cheap” on the airline’s part.

This is a very long flight and the first time I have flown on a Japanese airline. I was very impressed with the staff. They worked hard and offered food and drink regularly. Plane was very well cared for. The let room was good . Food was ok but better than other airlines.

It was very nice. I was a bit disappointed by the few meal services. There were probably more drink services that I missed while sleeping, but I would have liked the crew to bring more than one drink service before landing and to bring more than one drink service and coffee service after take off

Food was high quality. Crew was extremely professional, polite, attentive. Flights were on time. Plane had good media tech.

I wish the serve should leach and drink. Maybe because only 2hr

It was ok I thought because my flight was 1pm i was expecting to have lunch but it didn’t and after 7 hr finally dinner time was only chicken sandwich and next breakfast was an hour before plane land in Tokyo. so I should bring some food with me. Japanese flight attend was nice but the other was chewing gum and how she ask and respond to customers was not professional I felt. Maybe because Japan flight attendant is highly train and everyone looked very dress and professional so I was kind disappointed. I like that the bathroom was very clean .

Lovely airport at Haneda. Great food selection. Spacious and private boarding area with dedicated bathroom for each gate.

All was good, the only thing was it didn't run on time.

Great meal. Best seats ever! They need to teach other airlines how to do that.

The staff and crew on board were excellent. Business class however, was very weird. I thought we would have individual pods, but the way it was set up was unexpected. Not very private and If you wanted to lay down, you had to have an entire bed made up for you by the crew, rather than how Delta one works where you could just lie down whenever you feel like it. It was a 16 hour flight. I chose not to have my bed made, and that turned out to be a good idea because everybody who had their bed made had to wait for the crew to roll up their mattresses. So strange!

Crew were pleasant, happy to be there and were a joy to be around. Entire operation was professional, well thought out and ran like a Swiss clock.

Couldn’t request a vegan meal somehow but I noticed other people getting them

They announced food service but then never came around. We also couldn’t land so kept trying to get to runway and then had to come up and go around happened like 3 times and cause the child next to me to start throwing up

Good food and entertainment options. Great Staff that were all welcoming and caregiving.

The recline on the seat in front of me came back so that I was staring at the top of the man’s head in front of me the whole trip. He refused to bring his seat back up twice every time he was instructed to do so and only relented when he had a tray of good in front of him. And then right back in my lap!!! Horrible man!! I complained to the staff multiple times, but no one would address the issue. Otherwise, it would have been a perfect flight.

There was a snafu with confirming seats at check which left us in limbo for the second leg of our trip. I believe the ANZ app is not well integrated with the systems at the terminal resulting in this disconcerting error.

Carring crew, nice ambiance of the cabin, comfortable beds, good food well served. We liked everything.

Qantas are unable to service and unfit for purpose, they cannot transport Australians on time to overseas destinations. On top of the inflated ticketing, the Sydney flight to Santiago was impacted because the plane was delayed arriving and then further bungling by Qantas admitting the ground new ground crew in charge of cleaning were not trained. The impact on passengers with connecting flights was tremendous and long ques of frustrated passengers waiting for rescheduling. **Qantas has become the Australian Spirit of disappointment**

I was pleasantly surprised with my flight to LA with Qantas. Although seats were not the roomies, service was excellent.

The service and smooth landing. Food was delicious and the staff was friendly. We arrived earlier than scheduled.

Wonderful crew, good food. Absolutely loved the wine spritz and wish I could buy it!

Don’t like last minute airline change. Not able to choose seat earlier.

Enjoyed the new possibilities of in flight entertainment. Been awhile since I've flown, and that was a nice surprise. Being able to pick from such a variety was personalized and welcomed.

It's only a short trip from Sydney to Melbourne, which i have done many times. The trip met my expectations

Qantas cancelled my flight for no good reason and rebooked me into a middle seat.

I was in premium economy. My seat didn’t recline much - it was broken. My phone charger didn’t work.

Everything as good as can be if one flies economy bit not enough toilets!! People were queuing during the whole flight - there are really not enough toilets!!!

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

Wifi wasn't working on one of the UA flights after boarding.

The flight was delayed instead of leaving at 11 it left at 12.20

United WiFi is consistently unusable (it can take 10 mins to load a single web page). If you need Wifi to do work, be prepared to lose half a day of productivity.

Crew was not very helpful. They forgot to serve me coffee and had to wait for a long time.It looked as if they were not very happy with what they were doing.

Good movies, iffy pay WiFi, food ok- on time though and that was great!

Unfortunately this is not a happy ending comment. Positive: flown United before no issue Negative: it only takes one bad experience to not plan future travel with United Cancún departure was delayed by 1h20 minutes, connection in Chicago was 1h30 minutes. Flight departure time 6:08 Miraculously 7 of us ran 4 kilometres through Chicago to arrive at 6:00 to be told very rudely by the 2 unprofessional United attendants you missed your flight and that we should of arrived early. Did I mention that reason I was flying? I received a call that my brother was dying and to get home. They provided no assistance would not answer any of our questions, ignorantly walked away. Deplorable

Awful…flight was delayed more than 12hrs, missed all connections to Fort Wayne, IN, had to get flight to another city 2 hours from my destination, flight was again delayed by 40 mins because they did not have enough fuel, again missed a connection, finally arrived in Indiana at 11pm…but before my 2 hour drive home, ay, no Five That Our Luggage Never Made On The plane and Still In Chicago

If United expects people to use their own devices for entertainment they should put charging outlets in each seating area. I arrived with 14%battery power. That is not good when you arrive anywhere and need to communicate for transportation.

Boarding was friendly and quick. While the plane model was older with no live tv, the entertainment was full of movies and tv shows. All food was available. Pilots were very communicative with status of the flight. Flight landed on time.

Fresh fuit or veg snacks would be so great, but there are two good restaurants in Denver airport. Try Etais UDIS or Freshens DIA for nutritious delicious pita sandwiches/ donairs and crepes in Freshens.

Crowded plane but it flew on time and had friendly staff

Headphones for the movies have too much bass and can't be adjusted. Almost impossible to hear. Great movie selections but can't really watch them because you can't hear them. Also the system is very slow.

This was the first AC flight in a long time that we experienced no delays or frustrations. The gate attendant was extremely polite and accommodating to my husband who has Parkinson’s disease which made boarding extremely stress free. Flight departed ON TIME and was a smooth ride. If only all my AC experiences could be like this.

The Air Canada agent was very helpful helping with my luggage and cat carrier when I went there instead of United.

United force you to download their App to do the check-in.

I didn’t like the fact that all the customs officers went to lunch so I was in line for 90 minutes due to where the staff directed me. We were told three very different reasons for why the plane was delayed. It was a crowded plane with difficult storage situations for the Carry On bags. The Air Canada airline staff were all very good and professional. I was so disappointed in my cheese and fruit box as the cheese had molded and the fruit wasn’t fresh so I couldn’t eat the majority of the food. This was the last meal I could find as the restaurants had closed when I got in to my destination. I think you could work on improving the food quality.

There was no entertainment at our seats. The flight was comfortable and we had leg room. The snack we had was really good.

Economy seats were surprisingly comfortable, and snacks not too bad. Checked luggage arrived at destination without problems. It was annoying to wait until last to board as lowest-tier seats but understand it’s difficult to gauge when loading a full plane At least checked carryon luggage seemed to come off first. Annoying to have to use app to order food/drink when wifi availability didn’t allow time for it. Advance communication would have helped Food on menu seemed highly processed and unpalatable, overpriced and over packaged. So maybe a good thing to have missed chance to order

Once again my complaint is how close the seats are together. Also, the bathrooms were not very clean by the second half of the flight.
