Great first time experience with ANZ. Such a great customer service. The crew was very friendly and welcoming

Great airline service by the staff. I highly recommend it

Needed more leg room. Leg rest and entertainment system box took up a lot of space and I'm not tall. Breakfast was good. Poor quality of the entertainment options.

Boarded on time, smooth flight and "gentle" landing in Palmerston North. Ahead of time due to a tailwind

Time to upgrade those planes so you can provide first class.

My experience with Underpricer was not great. The representative assigned to me did not tell me beforehand that selecting seats, which i could not do through ANZ, WOULD ADD SIGNIFICANT cost to my ticket (all flight segments were reg economy seats. The seat selections for the ticket, MCI-AKL, AKL-PER, PER-MCI, cost $284 USD. I WAS NOT TOLD AHEAD OF SELECTING SEATS chosen by the rep OF THE COSTS and never received an itemized invoice of the seat selections.). The costs of seat selection, an option solicited as a service, with no mention of costs, should have been disclosed to me prior to seat selection and certaily should have been itemized. For all I know, the $284 was not referred from the airline but made up and taken directly by Underpricer. Next, when i checked in, united couldnt find my ticket. This is probably why i didnt get a seat selection on that flight and couldnt check in online, despite Underpricer prompts to do so a week before departure, or at the kiosk at the airport. I had to wait for special help at the counter, then was told that because the flight segment, MCI-IAH, operated by United Airlines via the ANZ. ticket, had changed schedule slightly since I BOOKED MY FLIGHT, the MCI-IAH segment had been decoupled from the rest of the ticket because the IAH layover was now 12.5 hrs AND DID NOT QUALIFY AS A THROUGH FLIGHT TO AKL.. This meant my checked bag could not be checked through to AKL and id have to pick it up at IAH, THEN WAIT MOST OF the long layover WITH the large checked bag until ANZ counter in IAH OPENED for checkING just prior to the flight. Apparently, although underpricer had notified me of schedule changes, they did not update the ANZ TICKET, leading to this problem. Finallly, although I RECHECKED TH BAG IN At IAH 3.5-4 hours before the scheduled departure and the IAH-AKL segment was a direct flight, ANZ LOST MY bag and it took 4 days to find it and get it to me. Not fun.

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

Great service. Food could be improved but overall a very good airline

While they turned off most cabin lights to allow people to sleep, I was bothered by how bright the side lights still were. It was still quite bright for me in a window seat, when I wish I could have slept!

Generally on time departures and arrivals, clean planes, sky miles membership provides great benefits (complimentary upgrades, etc).

N Everything was perfect from boarding to assistance to baggage in Tampa

Loved the crew! Sucks that we went from 1 hour and 8 minute layover to a 3 hour layover. But weather sucks like that.

Fast, lovely scenery, great info on the Delta flight screen about landmarks we were flying over. Great landing!

Long flight but comfortable and not freezing as I have experienced on Hawaiian flights to the islands. They gave us blankets just in case. Nice touch.

I took seat 15A in anticipation of window seat, there is no window.

Flight late, the waited for a long time for “personal” to arrive at gate to dock the plane in Rochester. So annoying. This flight was expected, why aren’t personel available for the jet bridge?

My recent experience was excellent on Delta! I flew with Delta Comfort and I was really comfortable in my seat. I enjoyed the in-flight service. The flight attendants were so friendly and hospitable. I love the snack on the flight as well. This was my first time flying on Delta and I will definitely consider flying with them again.

My flight was canceled on Sunday. Rebooking took three hours. Had to pay for accommodations another night. New flight was delayed for 5 hours, all that was sent was a 12 dollar food voucher, which doesn’t tell you how to use it. Then when we landed we had to sit on the plane for an hour before we could get off.

Late plane. Only one crew on the ground so we b had to wait for Denver flight to come in, board, and depart. At 78 yrs of age I was not pleased trying to get my connection. What really made me angry was the notification you sent me to hurry up or I would miss my connection. Why tell me to hurry up when you got me in late. It was not a good way of treating customers.

My flight time was changed without any notification to me which ruined my time sensitive plans so I ended up completely changing my travel plans and no reimbursement.

No screens or meal options. Freezing cold. Dirty seats. Left late.

I liked that my son and I were reseated next to each other (we had different bookings). I liked that it was a directg flight and mostly on time. I liked that you provided pillows and blankets. Flight attendants were generally courteous. The messaging through wifi did not work well. The food was not good. Seats are very narrow and I felt slightly claustraphobic in the window seat.

Some crew were unfriendly or in some cases just straight up rude.

Booked through Kayak Business, had a seat in middle and towards back due to booking rate, not comfortable.

Outstanding service, efficient & friendly crew, flight was safe, comfortable & on time

United Airline crews were very friendly and very attentive. 12 hours flight was gone like in a shorter one.

Food was surprisingly delicious. Space in the seat is horrible when the seating front is reclined. Movie offerings were terrible. Crew was friendly and helpful.

Flight itself excellent, but delayed so missed connection & got to destination 2 hrs later

Premium Economy Good crew, good service, excellent food. Seat back screen just not bright enough.

The crew was very attentive through out the flight. Seats were comfortable, nice flight bag with pillow and blanket. Food was okay, since it was a overnight flight seemed to go by fast.

Left early arrived early..right amount of talking from pilots..of course had to love the biscuit and water!

Boarding gate at LAX was too crowded—two gates next to one another

On time departure and early arrival. Flight attendant very nice.

The business class layout of chairs was weired. You are sitting directly across stranger.,

The SFO Lounge crew were amazing. The bartender Faris was great. Thanks!

Friendly crew is the only nice thing. Seats uncomfortable. Food and snacks horrible. Movies were the same as the first 10 hour flight two weeks before

Was not able to do a online check-in because the American Airlines system doesn't store our visa or other passport information, allowing us to have a trouble-free check-in. We were forced to have to check-in at the counter which Changes are upgrade status given that we were not able to check in much earlier.

Good flight, seated and had a water within 5 minutes. Crew was hospitable.

I was charge a baggage checking fee $68!! I volunteered to check my duffle bag which usually goes under my seat!

Very rude gate attendants in San Francisco who didn’t let me bring my little carry on (smaller than usual size) and after boarding I realized that there still were a lot of overhead compartment space (like a full section available in some spots). That made me lose 30 minutes at my destination at 1am and it could have broken something fragile that I had in it

Departed Palm Springs over an hour late because there’s only one gate, and it has always delayed by the arriving and departing flight to Toronto and the arriving flight from Vancouver.

The flight left late and I didn’t get a glass of bubbly upon boarding (which I’m used to when booking business class on other flights), but otherwise it was a pleasant flight with lovely, helpful crew members and I enjoyed my meal.

Couldn't fit knees, only 1 toilet working, didn't get anything to drink cause the stewards were not able to get to us

Flight was canceled for a reason they knew hours before but did not mention. Next the gate chnage from 37 to 38 at least 10 times. Ridiculous.

The flight from SFO to YVR was delayed and my bag did not make it to my next flight from YVR to SYD. It took almost 3 days after I landed to get my bag and when I got it, it was filled with dust

Great check in process in LA and good service The check in process as well as at the gate is way better in the US versus canada 🇨🇦

All attendents were very efficient, pleasant and happy. Everything went smoothly. The seats could have been wider. There could have been more free food instead of just one small bar.

I liked a lot , the flight attendant so nice ,the seat very comfortable I enjoyed the flight , I will do it again with Air Canada,
