I like Air NZ, but rather old plane seating in Premium Economy. Not very comfortable , nor very roomy.

I like Air NZ, but rather old plane seating in Premium Economy. Not very comfortable , nor very roomy.

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.

Aircon set too high so VERY warm and VERY uncomfortable.

Great! Flight was delayed by 30 mins but all was great. Thanks.

Arriving at Coolangatta, rows 20 forward, took the airbridge across to the terminal. It was suggested to those from rows 21 back, that we take the rear stairs and to be careful crossing the tarmac. That was all well and good. However, when we got across to the terminal we then had to climb three large flights of stairs to meet up with those coming across the airbridge. No elevator! There were people carrying babies and elderly carrying hand luggage that needed assistance from others.. There was no option to turn back.

Flew premium economy, well worth the extra. Much better seat size & space. Meals & snacks were lovely. Crew really pleasant. Internet is not great, not really useful for anything. Couldn't even send messages.

Overall, a great experience from food and crew. The only setback was that this was the Second flight from Air New Zealand within a week that was an hour late for boarding.

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.

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

Despite having numerous passengers held up by American Airlines delays. Qantas (an AA partner) closed boarding with 0 flexibility

Boarding , crew and meals were all amazing. Couldn't wish for a better LOOONG flight from Dallas to Sydney .

Boarding was effortless, the food was outstanding, the seats in Premium Economy were extremely comfortable, and the staff and crew were excellent.

PREMIUM ECONOMY - excellent !Brilliant new plane. Excellent tv catalogue. Good food. Good communication and service from all friend Australian crew. Good communication from captain. Best travel experience in years.

I couldn't hear all of the announcements. It was nice when they put them on the screen.

I liked boarding the plane. The staff were rude, the food was appalling and the chairs the most uncomfortable I have ever experienced

One of the best Qantas business flights I've had. Quality product

Loved the staff. The economy seats could have been bigger.

The food was terrible. And the flight attendants were very rude. One flight attendant wouldn’t help a passenger lift their carry-on. Another flight attendant wouldn’t give a man an extra blanket. And they walked by not even looking at the passengers to see if they needed a glass of water.

Enjoyed the new possibilities of in flight entertainment. Been awhile since I've flown, and that was a nice surprise. Being able to pick from such a variety was personalized and welcomed.

Crew and food was good, ok leg room if you don’t have a big box under the seat. And the seats are so narrow (I’m only 70kg), will consider an alternate airline next time

Food was absolutely pathetic. I wasted so much food which I thought was inedible. I also loathe the inflight entertainment system which has very little content

Boarding from DOH to SYD the Business Class were pointed in a separate gate but no one there to receive us. Otherwise it was ok.

The flight was delayed and one member of the crew was a bit rude. But apart from that all good.

The flight was good but my neighbor had the vent open full power for the whole flight and because the air was blowing from the side instead of from the top and I got very cold and ended up with a sore throat.

Boarding delayed, no communication. I left the lounge, and heard a final call, boarding started after a 30 minutes.

Bag check in at DC was slow. Boarding process was slow more due to customers unfamiliar with how to board properly. Food and service was excellent!

The hindu meal food did not taste good. Also the seats were not comfortable as compare to other airlines

Very tight seating. Crew seemed too dis interested and too slow to remove main meal trays.

The first and longest leg, Washington to Doha, was in a 777 that was very loud. This was an older aircraft. The second leg, Doha to Delhi, was in a much newer aircraft, an A350 and was very substantially quieter. The service was good on both, though as always, the crew leaves you trapped with your meal tray for a really long time. Additionally, the flight crew seemed inordinately afraid of turbulence, keeping the seat belt sign on for long stretches when there was barely noticeable turbulence.

Short. Nice quick flight, appreciated after Munich to DC leg.

The flight from Frankfurt to Pisa was cancelled and we were rebooked to route through London. The flight to London was delayed for maintenance issues and we missed our connection flight. Lufthansa automatically rebooked my wife on the next flight but I was not rebooked. I spent over an hour trying to get onto the flight. Ultimately my wife’s gate checked bag from Washington did not arrive in Pisa and remained in London. Very bad experience overall.

This was a small aircraft (relatively) and we were delayed half an hour on takeoff, which is not the airlines fault.

Flight delayed over an hour with plane on runway because of weather in an area of the country we were not in or flying to.

The very best airline service I have experienced. Better than domestic airlines first class and I flew Economy Plus!

The food was horrible. There was no. Wifi, and it was just terrible from bangkok to d. C

Boarding was 2 hours late and then we were delayed another 5 hours on the tarmac. I'm sure the crew were also tired, but some of them were rather snappy. The special dinner I ordered was not served, and they only served a tapas box on takeoff and breakfast before landing. That was disappointing in premium economy. However United was good at rebooking my connecting flight.

It was pretty good, they give a small blanket, neck pillow and earphones. The only bad thing was not big enough leg room for your bag and feet. They gave us a snack, dinner, and breakfast on flight and food was good considering it was on a plane

The crew was great. The food was typical, but decent. Everything else - mediocre to poor. The flight was late arriving - happily for us and our 49 minute connection (what idiot came up with that?)- in another concourse - that concourse changed before we arrived (ticket and app was showing the incorrect gate - when we boarded at the correct gate - known by the airport person pushing my assistance cart). Had I walked and read the screens or United app I would have missed the flight! May other people arrived late to the correct gate, having been victims of a last minute gate change, were also relieved the flight arrived late. The aircraft (Boeing 757) was a sardine-can due to an uncomfortable seat pitch distance. The material or seat was beyond not comfortable, but I'm sure they made a lot of money with that aircraft type. I spent a lot of time standing in the back (in the middle of the night/morning to rest my back). I learned my lesson - any trans-oceanic fight - avoid United or American Airlines - and look for Airbus or Boeing 737, 767, 777. Also, pay for business class or premium coach seating.

Crew was great. Seats are cramped and uncomfortable and I’m a small person.

It was a short flight so, everything went smoothly and we got to where we needed to be safely.

Loved and was pleasantly surprised by the food!! Request Lufthansa to help transiting passengers at Munich (confusion whether to go thru passport control or not).

Flight home was delayed multiple times, did not get home until 2am

Plane left an hour late, I missed my connection and my bow case was never even loaded on the plane in VA. I deal with this type of nonsense everytime I fly air canada.

We were forced to check in our carryon and were given a green label that said to pick it up when exiting the airplane. We were told by the flight attendant to pick it up at the carrousel instead. We spent more than 40 minutes looking for the carryon which appeared at the wrong carrousel. There was no agent at the united desk for help. There was no entertainment.

Confusing with Air Canada and United flight, it was a hell, no help, rude people there, stressful environment

Great crew and the plane was very nice! The problem was that we didn’t have WiFi on both of my flights. I found that to be very disappointing today when all the other airlines always have WiFi so I could work or watch a movie.

It was my first time booking from kayak and first time with Air Canada and I must say it was cheep and flight and experience was so good. My favorite KAYAK now🥰

Overall I will say it was a very good experience. It was as comfortable as can be expected for such a long flight - 12 hours from Toronto to Tokyo. Everyone was very pleasant and polite. Even the passengers were cooperative and trying to be nice to each other. Of course the space is limited on such a long flight. The bathrooms were actually very clean. The food was very good. I liked how there was a variety of food options. The in flight entertainment system was also very impressive! There were some children on the flight but they were well behaved and hardly ever crying. Great Job Canada Air! I will definitely fly with Air Canada again!

Flight was delay for 3hours then later canceled. I missed my work. It was a bit ectic and frustrating
