The flight was smooth and on time. Entertainment options were lacking and there was no food, other than some very boring snacks.

The flight was smooth and on time. Entertainment options were lacking and there was no food, other than some very boring snacks.

A better selection of entertainment would have been nice. I found nothing that appealed to me as a middle-aged traveler. The flight attendants were gracious, helpful, and attentive. It also would have been nice to have more bathrooms as the flight was full and the plane was big.

Appreciated the ability to get an earlier flight home after flying in from in from Japan. No problem with boarding or crew service. The limited choice of snacks, compared to previous years. Aircraft seats seem to be getting harder and more uncomfortable all the time. Overall, happy to be home

Both my wife and I thoroughly enjoyed our return home from Tokyo to Auckland and onwards to Palmerston North. We would recommend using the Premier Business class for long-haul travel, any day. Well worth the extra cost. Cabin staff were exceptional, Thank you

The Air New Zealand product is terrible, it's as expensive as a Jetstar ticket with add ons but with surely staff and old aircraft.

This flight was the second leg of a trip that began in Auckland, New Zealand. I was unable to find a way to select seats in advance. The boarding passes we were given in Auckland did not have seat assignments for the second flight. There was no way to check on it until personnel showed up at the gate in Los Angeles, immediately before boarding time. The flight was overbooked by one, and since I was traveling with my sister, we needed two seats. We waited in considerable anxiety for everyone else to board and when one person did not show up, we had to take whatever was left. At least we finally got on the flight although we were the very last to board. We were not able to sit together, of course.

The Premium Economy seats were very comfortable and the food was quite tasty. I did not use the entertainment system, but I was able to charge my phone and tablet with the seatback connection.

The seats are feeling very hard to sit on. All the padding is flat, like sitting on a park bench for over an hour

Nothing better than Air New Zealand. Top scores in every category.

We had difficulty checking in as United didn’t recognize the confirmation number and the agent was not helpful. We went to the United Assistance desk where the agent was able to process our reservation. We also weren’t allowed to choose seats in advance.

Good check in and helpful staff. Delayed for 1 hour. Took about 45 Mins to get baggage’s at DFW . Food was average ( Hindu meal ) . Overall it was good experience

Our boarding and flight was very good. However when we landed and pulled in to the gate it took 55 minutes for the jet bridge to be positioned next to the aircraft. That caused us to miss our ground transportation and it caused us unnecessary last minute transit planning and expense. Our flight was AA1733 on March 17, 2026

We booked with Qantas instead of Delta and we instead flew on American Airlines. American is not our favorite to go on. No leg room and the width of seats are a joke. Your are packed like sardines on American flights.

When I originally booked this flight, I was expecting to travel on Qantas. When the itinerary changed and the long-haul segment was operated by American Airlines, we were disappointed but remained open-minded. Unfortunately, the overall service experience fell far short of expectations. This was a long-haul international flight. Getting up periodically to use the restroom or stretch is inevitable, especially on flights of this duration. However, each time we stood up, we felt as though we were inconveniencing the crew. The tone and body language often suggested that we were in the way or disrupting something simply by moving about the cabin. As a result, I avoided getting up as often as I needed to and was physically very sore upon arrival. Meal service was similarly impersonal. The options were presented in single words “beef or veggie,” “pasta or beef” without any description of what was actually being served. There was little engagement or courtesy beyond that. Even simple expressions of gratitude were often not acknowledged. I am accustomed to no-frills travel and do not expect luxury. What was disappointing was not the absence of extras, but the absence of basic warmth and professionalism. On a long-haul international flight, small moments of courtesy and humanity make a significant difference. In this case, the experience felt transactional and dismissive rather than welcoming. I hope this feedback is taken constructively, as there is a meaningful difference between efficient service and indifferent service.

Flight arrived late with no one to help over 30 people rebook. I slept at the airport.

Business seats not as comfortable or private as most competitors (e.g. Qantas was outstanding), and movie selection was much more limited than Qantas or United has been recently

Hard to move and get out of my seat when the passenger in front is in recline position.

It was a good flight and no complaints. It just wasn't anything that was better than any other flight.

The crew were wonderful - if only the customers were as well behaved as the attendants!! Ha ha! If you could just talk to God and ask for less turbulence next time.... Juuuuust kidding....

Basic airline, aircraft and service. AA gets you from point A to B. My flight was delayed by 2 hours too.

2000 USD for a 10 hour flight on the worst seats I've ever flown in.

Seats are uncomfortable. This has been a trend in the industry for decades. Trying to fit more seats on each plane to increase profits at the expense of the passenger.

It’s always a great time flying with united airlines.

We got delayed three hours and nobody thought to have the bathroom fixed while we were sitting waiting to board? took a full hour to have maintenance come and check it off. Had to shut the bathroom down twice so that the pilots could go to the bathroom. Everyone missed their connections.

Women boarding passengers at the gate was absolutely rude and disrespectful of passengers. The flight attendant was absolutely delightful! Smiling and connected with the passengers. So happy. The seats are cramped and uncomfortable but I guess that’s just the way it is Communication regarding flight was excellent

As great a red-eye flight as red-eye flights can be.

Both of my flights arrived early and check in process was smooth

Everything was on time Will use united again for sure

I just think it’s unfortunate that Airlines have completely abandoned the idea of serving any kind of decent or even real food on flights, not even on a four hour flight!? Those days are gone, I guess.

The flight was delayed by two de-icings. The seatbelt did not work correctly. It did not stay tight.

Delays with no explanation. It could have been handled better.

Ceiling fell down and had to have maintenance come and duct tape it up. No WiFi on the flight.

A first class seat should fit a fat person, and this doesn't. The trays in the armrest are less functional than an ordinary tray in the back of the seat.

The flight attendant was friendly and efficient. The temperature was kept nice and cool. The plane was nice, but filthy. There were visible spills on my tray table. The gate agent was somewhat rude with her announcements and in speaking with other customers.

I appreciate that I finally got the seat I paid extra for this time. Thank you

I would have liked vegetarian and gluten free options for evening dinner time flight. I would have like a pillow on the international overnight flight . The veg wrap and oaten desert on the international flight was good

The experience at checkin for my American Airlines flight from Sacramento to LAX was very good including the assistance I received in getting my bags checked in and boarding passes printed. Was pleasantly surprised the my bags were checked through all the way to my destination at Clark International Airport in Angeles, Philippines.

Very poor food. Took more than 90 minutes for baggage to arrive at DFW

British Airways is an excellent airline. Comfort, food and airline personnel.

Absolutely terrible. Would never fly American again. 2 deplaned incidents and delayed by close to 24 hours. $12 meal voucher for first class passengers was an insult to the injury. Pathetic.

The flight was delayed, but not for weather. We landed over 3hrs later than planned.

The stag were helpful, kind and liked the passengers. The plane was pristinely clean! Great flight!

My flight was delayed more than once, but Air Canada updated us regularly. Friends on other airlines had much worse experiences.

My ticket did not exist when I got to the airport. I had to book another flight and was still charged by Kayak

Got denied my flight was told on Google that Air Canada was supposed to book me a flight back home because I never was able to go to my destination. They did not help me whatsoever. I had to book a whole new flight for that reason I would write this is zero

The plane was delayed an hour. Heard from other passengers that the Vancouver connection to SFO was never on-time.

My experience was good with United too But only not so good thing was that at Calgary airport I was not given lounge access despite of flying business. Aspire lounge denied it to me, which was unfair I feel

We left over 2 hours late and they didn't even give us a complimentary snack, when getting to the desk I asked if I could be put in a row with only 1 other person or an empt y one I was told the flight was full when the last two rows were empty. All around over it

they were super helpful. Agents at the desk got me on an earlier flight and I was able to get home several hours earlier.

This is a great non-stop YVR-MIA. Very comfortable plane, and no transfer through a city that gets major winter weather!
