Space between seats on Air New Zealand is generally tight. The crew on this flight was excellent! Very attentive and nice. You get free wine or beer and chips and of course the Air New Zealand candies. 1 hour and 35 min flight approximately.

Space between seats on Air New Zealand is generally tight. The crew on this flight was excellent! Very attentive and nice. You get free wine or beer and chips and of course the Air New Zealand candies. 1 hour and 35 min flight approximately.

Your entertainment could be better. I flew on Air New Zealand in January so was expecting a better choice in February...but no luck. Same choices and also could have a better selection. Otherwise, lovely service, the purser came to our seats to welcome us. Overall, very nice. Direct flight from Auckland to YVR was fantastic!

Air New Zealand over sold our flight and tried to bump us to yesterday. After several calls we got booked to United about 6 hrs before our original flight. No apologies!

Very quick flight so no time for refreshments. We took off. Then landed. The end. Seats were too tight. Very cramped Grateful for the short flight cos moving around wasn’t possible

Please add more Bollywood movies and recent movies to the entertainment.

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.

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.

Flight was delayed by 2 hours. Got lucky that i had a long connection, else would have certainly missed my connecting flight. Food is just okay, specially the breakfast is worse . Asked for water 30 mins before landing, the response is that we are landing so everything is packed . I guess traveling in economy that’s what we get. Probably business class passengers would get a different answer. Only good thing is that wifi service is available from auckland to lax for most part Next time will try united or American and then compare.

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.

They are my favourite airline in the world by a million miles.

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.

After already paying for excess luggage prior to flight, i was advised AT check in that i had to pay $816 or forfeit my flight! The lady at the counter was SO rude and had already started offboarding me when i said i would pay it after asking her three times for the exact amount! Have lodged a formal complaint yet heard nothing. Will not ever travel via Qantas again

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

My flight from Dallas to Sydney was cancelled. My entire trip was rerouted to include the following: Hartford to Washington DC Washington DC to JFK JFK to Auckland Auckland to Christchurch I paid for an aisle seat on the flight to Auckland and was asked if I would take a window seat to accommodate a family. The agent at the podium failed to mention that the family had a 3 month old baby and that a bassinet would be used during the 16 hour flight. The only way I could get out of my seat was to crawl under the bassinet of the sleeping baby. I think it is wrong that I was no given the choice to sit in another seat, that the agent knew what she was doing and chose to not properly disclose my seating arrangement. Terrible treatment.

they ran out of fruit for breakfast and so I just had a yogurt instead. other than that the flight was good

by the time they got to our row, they were out of some of the food options. games and movies were great but maybe more game options like tetris or pac man would be great

Great as usual, some delays but well communicated and made up for in the air

Poor! This flight was delayed 14 hours. There was no assistance in helping customers find other routes to their destination, nor any other kind of support. It was a chaotic experience. I'm not likely to fly with AA going forward.

Airport experience at Newark was not great. Only one gate open at immigration for US passports when multiple international flights arriving at the same time. Then having to take a train and a bus to different terminal only to have to clear security again, after I had already gone through at my initial departure location. Older plane, no entertainment screens available, and for economy plus, seat was very uncomfortable. Crew was friendly and this leg of my flight was on-time, even though I arrived later than initially scheduled due to 1st flight being over 2 hours delayed and missing my original connection.

I upgraded my seat and was promised it would be next to the emergency door for extra leg room and they said it was premium plus but it was at the back of the plane...same thing happened from Newark to Dubai

Everything except the food and entertainment. It was a great experience though

Bad food, bad service, cold cabin with no additional blankets when asked for (they told me they don’t provide additional blankets). I’m a frequent traveler and this is one of the worst companies I traveled with (by the way I thought that I booked my ticket with Lufthansa but I didn’t see that the flights were handled by United).

United Airlines is my preferred airlines and I am thankful for Gary who also help support me on the phone to switch my flight literally last min.

Not being stranded in Chicago for her airport to 11:30 tomorrow morning the 3rd

the whole trip was smooth, and as comfortable as flying is these days. flight crew was friendly and very courteous and helpful.

Very poor. The flight was delayed from Toronto because some forget to do there job . I got to my connecting gate in San Francisco 10 minutes before the departure.but this didn’t let me board even though the flight was still there for an other 30 minutes. The the gentleman at the unite airline desk told me that they usually wait for passengers but air Canada called and told them not to we I been rerouted to Manila instead of Hong Kong . In San Francisco they mad me check in my carryon bag . I was told the it will directly go yo ho chi minn cuyt but I was told that by the Vietnams airline desk that’s not there I’m 10 hours behind my scheduled flight and looks like I I’m going without baggage. I don’t have a chance of catching ..

Great other than a couple very drunk guys that for a while kept bumping my seat from behind. The staff did their best to control them. Even refused serving them alcohol and allowed the gal sitting next to them to move.

The attendant on board was amazing. She should be doing business/first international long haul.
