Liked the non-stop option, can always use more leg room!

Wonderful Airlines…our American Airlines could learn from ANZ. From boarding to landing everyone was professional and gracious. Kiwi’s really are the nicest of all people! Thank you

typical long haul economy flight. Food was mediocre, inflight service was average. Offered in flight snacks but in seat ordering didn't work. Entertainment was good.

Overall, a great experience from food and crew. The only setback was that this was the Second flight from Air New Zealand within a week that was an hour late for boarding.

The flight attendances were very helpful and friendly ! Dinner and breakfast were great . The seat was not too comfortable though .

New Zealand crew were attentive. We were not informed that we needed transit document to pass through New Zealand. A checkin employee helped with this for which we were thankful.

Overall good. We had to transfer to Bradly terminal. We had requested wheelchair assistance. The bus that picked us up had to wait for other passengers. The wait was long. Then, at the Bradly terminal we had to wait an extended period of time for the wheel chair assistance. These delays caused tension at checked in and resulted in arriving at the gate as passengers were boarding.

The boarding process was less than ideal. While I liked being greeted with “Kia Ora”, the rest of the process was very average for business-class travel — queue, crowding, no clear separation between economy and business premier. The aircraft felt old, even though I believe it was only 6 years’ old. Travelling in Business Premier in Air New Zealand is like sitting in a glass bowl. One can see everyone, and everyone can see others. Very bad structuring of seats. If you have a choice, fly another airlines like Singapore Airlines for business — I had the option, but chose this flight due to it’s departure time. Regrettable decision. I had opted for Vegan food choice. Very poor food as well as service. It is as if the chefs preparing the meal have little idea what nutritious, healthy and filling plant-based food is. And the crew were totally uncoordinated. In the main dinner meal, the first thing I was served was a fruit bowl, and then followed by other items. No mention was made that the fruit bowl (served first) was the dessert! And then after my meal tray was cleared another steward (not the one who served the main meal) comes around asks me that now that I had had the would like the dessert. I said yes, please. He went off and comes back to tell me discreetly that I’ve already had my dessert! He also didn’t know what the dessert was — and I guess it was the fruit platter that was the first item I was served. I was traveling with partner, who had similar experience. For her, they just cleared her table without offering dessert. Extremely poor coordination. The area behind the seats was extremely dirty. I just happened to use the overhead light to try and locate something that had fallen, only to be horrified at the dust, crumbs and all kinds of other particles. The only good thing about the flight was that when it ended, our bags came very very quickly. But that I guess is more to do with airport operations for Air New Zealands at Auckland Airport rather than the flight itself. I would think very hard next time I have to fly Business Premier in New Zealand, especially on Boeing 787-9NZM, which this plane was. Basically if you are selecting seats and find that they are at a diagonal angle, do not book this if you are looking for luxurious travel. Better off with premium economy or a good economy seat. The quality of food and service indeed was way below par.

Gate agent was fantastic in Auckland. They wanted to charge me for my two bags even though I was gold member with United in Tonga. So I had to pay for an upgrade. The meals on both flights had no vegetarian option. The only one item the salad was not tasty at all. Good thing I had brought my own snacks. The bread was white roll which is so not healthy. I think New Zealand air can definitely improve their food offering.

Can you please process refund. Mum died and dad went to Pakistan to bury her after cancelling flight.

American Airlines was their usual junk service — but at least it got us down to LA. I was more irritated that while they codeshare with Alaska Airlines in Seattle, they could not out our flight on one of these, opting for one of the small SkyWest operated American Eagle flights — and causing a 14 hour layover. Which I accepted due to a $2000 difference in airfare — that said it was irritating for a flight that usually would have cost around $100 extra, if that.

nothing to complain about w/the food, and professionalism of the crew. i just cant stand being on a flight for that long of a time.

Everything was great from the staff to the seats and food. The plane was timely taking off and landing.. I couldn't have asked for a better experience (especially on such a long flight)

Good communication regarding any updates time of flight and flight delayed. The fight was delayed by two and half hours at eleventh hour. That was unexpected, especially when you international passenger.

The service was excellent. The quarters were a little cramped in Economy, and we had to exist there for 18 hours.

It was very nice. I will try to fly with Qantas whenever I can.

Terrible. 6 hour delay with no explanations and only 15 dollars in food credits. A disaster. I'll just leave it at that.

We lucked out. The passenger who was supposed to be in our row changed her seat, so my husband and I had 3 seats for the 2 of us. We were able to stretch out a little which made the trip much more tolerable.

We paid for business class seats for the comfort that comes with that but couldn’t use the bathroom as it was full all the time.

Flight was cancelled about 1.5 hours before departure. Replacement flight provided scheduled 1 hour later. Late boarding, late departure and arrived Melbourne nearly 2 hours after originally scheduled.

Did not even get on board. Was told I needed an esta agreement. Was not aware of this when I booked the fare and not told about them

Cramped seats. Audio jack for the in -flight entertainment was broken.

Flight was great albeit the long line before the int’l immigration given the timing of the year.

They canceled our flight and left us stranded to figure it out

We appreciated the friendly, efficient, and professional flight attendants. A wider selection of hot foods would be nice.

Did not have enough time from Venice seaport at Ravenna to get to Venice airport in order to make the scheduled flights. Need to have at least 3+ hours from ship docking to airport.

Everything was very good. Was able to change a make run flight leaving on direct earlier in the app -seamless!!! Well done

Being stick waiting for gate at ORD cause me to almost miss my connecting flight…being deaf United made no no effort to keep me updated as I couldn’t hear the PA

As usual, United scheduling is completely misleading. A 54-minute layover at O’Hare is too short to make a lot of connections, especially since the flight landed “on time” but had to wait on the taxiway 15 minutes for a gate to open up. Then it takes another 10 minutes to exit the plane before one can run to another concourse to catch a connecting flight.

The seats on the aircraft are like sitting in a rock. During the boarding process they recognize Active Duty Military, why don’t they recognize Retired Military. I’ve always preferred Delta, this flight confirmed why I still prefer Delta.

Other than being delayed 5.5 hours and having to get a hotel because I missed my connecting flight, it was an okay flight. No in-flight Wi-Fi or entertainment.

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 from Buffalo to Chicago was on an older and smaller plane. Seating was tight. Looking closely at the interior of the aircraft there were definitely signs of aging and wear.

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.

Airplane was cold. Flight attendants were rude. Phone charger did not work. No food available.

3hour delay In the last 3 months i had 3 flights and 2 of these had a more than 2:40 hrs delayed

My initial flight to ORD was extended without reason. We circled the airport a few time and then drove on the ground for at least 20 minutes. These kinds of delays are annoying but somewhat expected… it would be nice if the crew would make an announcement to give updates on how long we could expect to be delayed.

Fantastic. I am low vision and was impressed with how helpful and accommodating the service tam was. It was super appreciated! I was pleasantly surprised about how delicious the food was. Like, “I wish I had more even though I’m no longer hungry” delicious. 100% enjoyable trip.

The flight was uneventful. What was a problem was I was delayed getting home one entire day because the flight from Sacramento was delayed. That made getting to my connecting flight impossible. I had to stay another night at the hotel and incur that expense as a result.

Flights were on time both ways, such a big plus! Staff was very accommodating and friendly. Question the choice of snacks that, which on both flights was dairy based. Appreciated using bottled water.

Service was excellent, but they ran out of food options by the time they got to my seat (row 36).

The idea of needing to go outside in the winter to board in icy cold temperatures is totally a non starter for me. Seats were very uncomfortable though the leg room not too terrible. Attendants were nice

The experience was good. Flight was on time. Liked how they offered to accept carryon baggage for free before as I was checking in online.

3 hours late departure with no explanation. $160 luggage fee (two passengers) for less than 1 hour in the air!

Flight was delayed by 45 min. No problems. Everyone took it in stride.

Crew was friendly and helpful; cabin seemed roomy even in economy class.

The flight attendants that assisted me were exceptionally nice, kind and helpful

Something wrong with the plane so had to deplane and waited over 2 hours to finally leave

AC needs to update their fleet. Too many mechanical issues, dated planes and too many delays

The flight was delayed for 4 hours and the airplane was really old cuz not one thing was working.
