The air New Zealand employees who assisted us with wheelchair aid on Auckland made our transfer from flight to the next seamless. Also were amazing in helping with our luggage and customs in Brisbane.

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.

The entire process was excellent! The economy sits are a bit snug so I'll have to be sure to purchase premier or business class next time but, other than that, food, service, attendants were exceptional. Gate agents and ticket agents too!

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

Short flight so no entertainment, turbulence so no food service - overall flight as expected

All was good, the only thing was it didn't run on time.

Great meal. Best seats ever! They need to teach other airlines how to do that.

I upgraded to first class only to find out that I still had no access to the sky lounge without a sky miles card or AmEx (something that should be emphasized outside of the fine print!) Also, no food or drink service provided during the flight, so I basically paid 4x more just for “free” checked baggage and a bigger seat. Not worth it.

I appreciated friendly service from check-in, to boarding, to in-flight amenities! Attendants were accommodating and helpful. Thank you! Elaine

Delta was really good about being transparent with why we were delayed it’s just that’s the plane was really old and outdated and a lot of the comfort and amenities we know Delta to have did not shine through

Bottom seat cushion is almost non existent. Very uncomfortable seat.

Delta was great the entertainment was outdated. Screen was very small and didn’t work.

Flight did not have seat back entertainment and the wifi was iffy.

Pretty standard flight. Delta has a good selection of movies.

The WiFi has been awful on my last few Delta Air Lines flights.

The seats are uncomfortable, feels like a small seat pad on plywood.

The seats are uncomfortable and there was no power to recharge a phone.

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.

Much better than I expected for such a long flight.

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.

Good - better than other airlines in terms of food and seat comfort.

It’s a very long flight and there are so many people on board. Perhaps a warm washcloth now and then to freshen up

The crew was very helpful to my family, especially when my daughter became sick during the flight. Will fly with them again.

Too many passengers are bringing on too many large items as part of carry on baggage where it should be checked in. This is not the fault of Qantas but the stupid mindset passengers have now about trying to bring anything and everything on as carry on luggage where it should be checked in.

Better than expected, normally I don't use this airline because they are too expensive for me, but if you can afford it, good on you, you won't regret it. Regards.

The flight was delayed over 2 hours. We had to wait on the plane and the air conditioning was turned off. The food was average and the cutlery was wooden!

Overall good flight. The pilots were excellent. It was a nice flight, but the seats were a little uncomfortable.

There was no air on the plane and it was very hot.

The free snack options are pretty pitiful for a 2.40h flight.

Good even though flight was delayed, the crew was prompt and efficient.

No access to the Wi-Fi, noisy group of people made it difficult for me to hear through my earbuds. Snacks and drinks - limited service when your seat is at the back of the plane - people up front are always served first and the back gets whatever is left. Not pleased.

In this flight we had selected seating for our family in the middle of the plane in a 2x2 format. The airline changed them to the very back row of the plane and split them to 3x1. Why pay for seats that allow seat selection if the airline will just move them to the worst seats in the plane?

Never happened, because of the first delayed flight I lost the connection and had to wait overnight and take two flights to reach my destination.

The plane was delayed ~ 40 minutes. Communication could have been better. The entertainment was poor. We were not offered headsets by the flight attendants. The arm rest pad did not work properly, thus, I could not select what I wanted to watch.

A/C wasn't working. Made the 1.25 hour flight seem like 4 hours! Even at altitude it didn't cool down.

Great flight. WiFi worked great and the crew was awesome.

The people are great! The trip to Japan is simply never ending!!! Not the problem of the airlines, though.

United agent at FLL excellent - due 55 min conx at ORD rerouted us on an earlier departure via DEN and got home 5 hours earlier than expected

I bought a ticket from Brussels to Fort Lauderdale, Florida, USA via Montreal. When I went to the airport, I learned that I needed a Canadian visa. When I bought the ticket online, there was no warning saying "If you are not a US or Canadian citizen; You need a Canadian visa." I asked for my money back, but the staff at the airport said they couldn't help me. I said, "Make the ticket open, I'll fly later," and they said no. I looked for this information on Air Canada's website. They've hidden it so well that it's impossible to find it easily. I understand that Air Canada makes millions of dollars in unfair profits by selling tickets this way. Why don't they ask when purchasing? They don't ask; because they're making money. Every year, perhaps thousands of tickets are subject to this situation. I will use all my rights and complain everywhere. Maybe they won't give me my money back, but I would advise anyone buying ticket to be careful from now on.

Friendlier staff who are nice to the elderly who need assistance

They intentionally delayed the flight by half an hour to accommodate a few fools who didn’t show up in time to clear customs. I missed my connector, missed an important meeting, and was charged a rebooking fee. Never again

Never flew with AirCanada before. Was a super duper flight every time and on time! No changes or delays!

Everything went very smoothly and the staff was courteous and friendly. I was really happy and pleased with how well the plane was flown because the departure, descent and landing were really smooth with no sudden drops. The plane’s interior was clean and nice and new in appearance.

Air Canada is the best company I’ve ever flown with. If I had the money, I would only fly with them.

Hated charging my devices. The location of the outlet was inconvenient. And no USB connection. So outdated.

Lots of turbulence and had to reroute to Calgary, spending the night there, arriving home a day later. The staff were organized and pleasant, even though they were stressed and tires
