I was not even on that flight and did not even book a ticket. Kayak did a phenomenal job

The disembarking steps in Wellington were precarious and I felt quite insecure. There was no one on the tarmac to greet us and help. The embarking ramp in Blenheim was much more satisfactory. The rest of the flight was fine.

Entertainment screen froze and had to be reset. Noticed it happened to other passengers as well.

My flying experience was not great. The temperature was ridiculously low. I had a sweater and a big jacket and even then. Since my ticket was an economy ticket, I suppose I didn’t deserve a blanket as they were only available for business. The result, o got a cold I have not been able to shake off in 6 days which has absolutely ruined my stay in Japan as I hasn’t had the chance to leave my hotel room. Everything else that was good, had overshadowed by this. BE A LITTLE MORE HUMAN

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.

Air conditioning was turned to the wrong setting. Way too hot. The entertainment system kept resetting and didn’t work half the flight. Said something to the crew. They didn’t do anything to help. Plane had a mechanical problem that resulted in 2.5 hour delay. Boarded the plane, had to disembark and get back on.

Good and appreciate the effort Air Zealand puts into using more environmentally friendly food containers and utensils. yay! One of the better airlines for this for sure. Still some bad stuff, but at least Air NZ is trying. :) Also really enjoyed the bluetooth option for personal headsets. :)

I was trying to get confirmation on if my luggage was going to be moved to the earlier flight (I requested standby to get home earlier) and was unable to get help from those working at the counter. The request to be moved to an earlier flight was handled smoothly through the app and appreciate the ease of the request.

Kayak did not propagate my United miles account and I had to manually get credit.

Like: Aircraft was better than others I've flown in. Crew was great, food was very good. Air New Zealand is now my favorite airline. On our long flight from AKL to YVR there was enough room for those of us in Economy to stretch a bit. My sister is disabled and they took very good care of her and me. Best entertainment offering of all the other airlines. Not so much; Flight from AKL to YRV was delayed BUT they recovered really well so no complaints here. Pretty petty point to complain about. Only negative I have. I will recommend to friends.

Teeny tiny bathrooms, crew was not realistic about when we'd arrive.

Check-in, boarding and the flight from Phoenix to Houston was quick and easy. The flight from Houston to Shreveport was delayed 5 hours. It was frustrating but I think United handled it the best they could.

Some flight attendants were great others were cranky. Seats were very tight and sitting on an aisle was very hard as the carts and people walking constantly bumped shoulder and arm.

It was great with United overall except for two things. 1) It was a 5-hour flight and we were with kids, so we were asking for extra snacks. They were extremely reticent to dole them out even though there wasn't any meal and the kids were starting to hit their limit towards the end. 2) Baggage didn't arrive until 80 minutes after we landed.

They lost my luggage, so, not happy. The crew was nice but my suitcases never made it, still trying to find out what happened!

The staff was hospitable and professional. The seat had a bit of wear. The winner shade was stuck 1/4 open. I received the best of both worlds. The morning sun was able to come in and blind the screen i was trying to use while at the same time it was too low to look out and enjoy the view. Rather embarrassing for a 1st class ticket.

Perfect flight. Smooth flight. Arrived 20 minutes early at destination. Excellent service.

The flights were on time which was great give. It was holiday travel season and there’d been some weather issues. The only complaint and this is every time with United is the terrible seat design. The head rest is not built for comfort and having my neck bent forward for a cross country trip reminded me while I try not to take United flights as a rule.

I’m so sorry, I can’t remember her name, I believe it was Dimpti. She was stellar, also a mature Asian flight attendant, lots of flowers in her hair, just as amazing! But literally the crew was AWESOME . Only downside is there weren’t any charging outlets. Maybe I needed to ask a flight attendant , but it would’ve been nice to have one easily accessible.

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