Great airline service by the staff. I highly recommend it

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

The food was not as good as Air New Zealand. The veg pasta was pass-able but the veg cibotta sandwich was dry, hard and not up to par. The coach staff were attentive and accommodating.

Overall the plane was good and the crew great. The big disappointment was the skycouch. Maybe it would be good if you were a parent with 2 small kids travelling but as a couple it's hopeless. It's impossible for 2 adults to lie down so one ends up sitting. We split our time with one lying and the other sitting. We both got more sleep sitting upright. We will never book one again and don't recommend it to anyone.

I flew United from San Francisco to Auckland. My connecting flight from Auckland to Christchurch was canceled with no explanation. I was finally told the cancellation was due to fog. Even though it was clear when we landed. I am from San Francisco, I know what fog is! And I didn't see any fog. I was told the next available flight was 7 hours later. Unacceptable, they should have had a flight ready to go as soon as it was deemed safe to take off.

Two hours was not enough time to transition from the international to domestic terminal. You have to go through customs, a biological hazard check, gather your luggage, take a bus to the domestic terminal and recheck your luggage. The bus was slow and crowded and the lines to recheck your bags were very long. We missed our connecting flight. Initially, the Air New Zealand officials were not helpful at all in helping to get us on another flight. Told us we would have to buy another ticket for a flight 11 hours later. Found another agent that was more helpful. He helped arrange to get us on standby for another flight three hours later. Had to ride in jump seats next to the flight attendants, but at least we eventually got to out destination.

At Coolangatta International it is difficult to hear voice boarding announcements when away from screen announcements.

Would have been nice to have decaf coffee as an option, and perhaps a scone

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

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

Very comfortable seating and the Flight staff were very attentive. The premium economy section that I was seated in was very clean, updated, and well appointed. I would highly recommend flying United Airlines as this experience was better than the Japan Airlines business class that I flew several months ago.

United needs to step up their game. Delayed flight leaving Seattle, San Francisco. Older aircraft, not very comfortable.

Had to cancel first flight because Airporter Bus took over 3 hrs to get to airport which resulted in an extra $378 dollar fare . Is there anyway I can be reimbursed for initial fare since it was not my fault? Sent from my iPhone EJ Ledet

Delayed by 2.5hrs any longer and they would’ve had to honour their own policy for breaking their own rules and regs. Not cool, especially when I have an infant child that needs to stay on a routine and they get schedules.

They had three choices for snacks - but you could only have one - and they ran out of the dark chocolate before they made it all the way down the aisle... Packed flight - limited service.

They opened my checked bag and even though my lock was tsa approved, they loose my lock and left my bag just like that. Incompetent people, very upset about it. I’ll try to avoid traveling with united

We fly to Ecuador frequently. Checking in is usually a hassle because most United agents take some time before they can verify that my passport doesn't require a visa to Ecuador. This time the process was even longer due to the cyber attack. But she was really nice to us. So glad we brought plenty of snacks to supplement the 3 flights from SEA to GYE.

We had selected seats in the app that were a 2x2 format in the middle of the plane. Our seats when we got on the plane had been moved to the back rows in a 3x1 format. What’s the point of paying up for tickets that allow seat selection if the airline will just change them?

The new Airbus A231neo has neat tech but the economy seats are so tight together that I always had my shoulders against one passenger or the other. I was very miffed that Basic Economy REQUIRES check-in of bags other than your personal carry-on; if you want to offer low-cost airline prices and then add services for a fee, just let me carry on my duffel. Hell, I could have put my carry on IN the duffel and called it a day but the gate agent would not let me; I ended up paying $40 for the risk of losing my bag. Not the worst flight, but far from the best.
