We got to experience Premium Economy from Sydney to Auckland and it was a great experience wiht Air New Zealand. The crew was friendly and helpful.

Boarded on time, smooth flight and "gentle" landing in Palmerston North. Ahead of time due to a tailwind

Time to upgrade those planes so you can provide first class.

The flight was smooth and on time. Entertainment options were lacking and there was no food, other than some very boring snacks.

A better selection of entertainment would have been nice. I found nothing that appealed to me as a middle-aged traveler. The flight attendants were gracious, helpful, and attentive. It also would have been nice to have more bathrooms as the flight was full and the plane was big.

This flight was the second leg of a trip that began in Auckland, New Zealand. I was unable to find a way to select seats in advance. The boarding passes we were given in Auckland did not have seat assignments for the second flight. There was no way to check on it until personnel showed up at the gate in Los Angeles, immediately before boarding time. The flight was overbooked by one, and since I was traveling with my sister, we needed two seats. We waited in considerable anxiety for everyone else to board and when one person did not show up, we had to take whatever was left. At least we finally got on the flight although we were the very last to board. We were not able to sit together, of course.

The Premium Economy seats were very comfortable and the food was quite tasty. I did not use the entertainment system, but I was able to charge my phone and tablet with the seatback connection.

Nothing better than Air New Zealand. Top scores in every category.

We had difficulty checking in as United didn’t recognize the confirmation number and the agent was not helpful. We went to the United Assistance desk where the agent was able to process our reservation. We also weren’t allowed to choose seats in advance.

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!

We had a cancellation due to weather, but the American Airlines staff was very helpful. Once we got on a plane, the trip was great.

Great food and good entertainment options for the long flight.

It seems that qantas are trying hard to regain their status as Australia's premier airline. I only flew economy but happy with the service entertainment, food, configuration everything.

I never flew with alliance. Kayak is a joke and none of the flights or times were correct. Won’t ever use kayak again

I missed my flight due to unforeseen circumstances It was, however , an excellent price !

Loved the food and beverages available, spacious economy class, excellent entertainment

Very good overall. Highly recommend for all flying to Australia

Helpful staff when I felt unwell. Qantas need to have an audio/music channel so you can listen to various music/.artists

We had bulkhead seats in a A380 in the upper deck in seats 31 D and E. Storage was very limited other than in overhead bin - which is not within reach when in seat. Yet paying same price as others in premium economy who have a lot more storage within arm’s reach. Seems very unfair.

On the Qantas flight, I could barely hear some of the announcements. It was better when I could read them on the screen.

These airplanes should be illegal. The seats are two tight, it is a safety issue. Wheelchair support was ridiculously slow. We almost missed our flight.

This flight is a quick way to get to Chicago, but a bit expensive.

The clerk at check in for my bags was very rude. My credit card was hacked during my vacation and she told me it was not possible to pay in cash for my bag. “You bought the cheapest ticket, you should have bought a ticket that included a bag. If you cannot pay with a credit card, we will not let you on this flight”. She spoke to her supervisor and then told me , I could ask other passengers, if they would use their credit card to check my bag. I had to beg 5 different people, till one agreed to use their credit card. I payed them cash of course. This was a very stressful and humiliating experience for me. I strongly suggest you build in some kind of provision for travelers who got robbed.

O’hsre taxi and deboarding took 40 minutes. Needed 20 minutes extra time between connecting flights to avoid running through terminal.

Flight crew was super friendly and helpful. Food was frequent and honestly pretty good. Plenty of on-board entertainment. Economy seats are super cramped for such a long flight, but the crew allowed people to get up and stretch, and kids could wander with their parents, so we all made it work. Overall a very good experience.

Standard flight with a drinks and a snack- overall very quick flight. The flight attendants were very strict, bordered on rude.

Starlink is great Crew was polite Business class didn’t get a welcome drink just water and snacks were ok

Delayed - weather wasn't bad at either end. Also sat on tarmac in ORD.

very average service no complimentary alcoholics drinks unlike other airlines such as Porter airlines No decent seats available during check-in time the day before

boarded early to only find out that flight would sit at gate for 45 min to an hour. Landed in chicago and sat on runway for over an hour before got to gate. Total delay was extensive for a 45 min flight door to door.

Awful, tons of delays, I got into Chicago multiple hours late meaning I hit the very traffic I tried so desperately to avoid. Just empty apologies from American Airlines text alerts. Trash behavior from a trash airline.

They lost my baggage and I am still struggling to the information and update

The homeless eat better than what was served on that plane. Pretzels and ice cream? My last trip to Europe. Everything is small, but the bill.

Awful customer service, horrible experience. We travel a lot domestic & international- worst flights to/from ever. Brief bkgd as Inhate to relive this experience: booked and chose 2 seats 4 months prior in Premium Economy - last row end seats close to bathroom, no one behind us, plenty of legroom;, underwear storage — flown this was on other airlines, love it. We receive notice 4 days before scheduled overseas flight - plane has changed, new seats assigned. Seats are split into single seats, opposites of the plane, FRONT Row so no reachable storage. Called BOTH British Air & America. American “switched planes and the seats you want are taken;” British Air “Yes, we’ll be glad to accommodate you (type type type). Just ask at the Gate and someone will give you new boarding passes with seats together in middle, OK?” — OK. —At Gate the attendant looks us up saying “No, it is an overbooked flight and yours are the only seats available.” But but but wait, “We were TOLD our seats had been switched and seated together?” Gate attendant “Well they were wrong and don’t change your seats. Your original seats are where you’ll sit.”. Right. No help WHATSOEVER. We sit opposite on way there, wife VERY disgruntled, a Tol 5 worst ways to start a 3-week bus tour of UK. We promise to NEVER FLY AMERICAN OR BROTISH AIR EVER, and we have 3 more extensive trips planned..

Requested early boarding to disinfect seat, tray table, etc. before general boarding. Instructed to board after wheelchair passengers. Waited on jet bridge behind 12 wheelchair passengers. Stopped immediately after entering plane to wait for gate agent in rear of plane cleaning a seat that was wet, got to my row and found both seats adjacent to mine already occupied, with the lack of room making it impossible for me to clean my own space and defeating the purpose of my boarding early. Cleaned the armrests and tray table as best I could.

The wifi experience is awful. I had to try again and again, taking over 30 minutes, to connect to the wifi. I had to watch the same two ads over and over until I was finally successful. Once connected, it was anything but "high speed" and disconnected at least three times during the flight.

It was good, the staff was great, and the food, was as usual, tea and biscuit. Bathroom was clean, and the plane was clean as well.

Very good I can’t complain one bit. Thank you American Airlines for making my flight enjoyable and safe!

The staff and service on American Airlines were truly outstanding. I had requested wheelchair assistance for my mother due to her knee issues, and the team went above and beyond every step of the way—from boarding in Boston to our arrival in Chicago. Their care, professionalism, and attentiveness made the entire experience smooth and stress-free. I’m very grateful for the support they provided.

The new planes (American Eagle) are beautiful and especially comfortable. The flight attendants are consistently professional and courteous. And, while it may seem inconsequential, the new liquid tube of coffee creamer—in contrast to the powdered coffee creamer—makes all the difference in a cup of coffee.

The flight was smooth, the plane was spacious and clean, the staff was kind and the food was decent.

Pretzels were a bit dry and dusty, however it is nice to have a choice between sweet and savory snacks.

Flight crew was great, and even the crew for checking bags! I had a question for a friend of mine flying tomorrow and the man I talked to was awesome and answered my questions and looked up things for me when he didn’t have to! I was able to give her current & accurate info for her flight and she was so appreciative too!!

Never flown with Air Canada before, but it's now a top choice! Loved it!

Horrible crew, horrible seats configuration, ridiculous space in the toilets, Air Canada is no longer a option.

Crew at gate and onboard were just very OK, not very friendly and honestly seemed bothered to be there. I will give a shout out to still selling headphones for those who forgot.

Flight Boarded and departed on time. The Flight crew was very friendly and accommodating. The aircraft was clean and free from clutter and debris. I will be happy to recommend Air Canada to my friends and relatives for their flight needs. They were very attentive and responsive to our needs as Senior citizens.

Another good flight experience with Air Canada. The business section did not feature the full length sleeping arrangement, but this was a shorter trip. The food was excellent. But the flight crew was truly top tier: friendly, cheerful, helpful at all the right times. Air Canada truly outshines all U.S. carriers.

Flight operated by PAL. We boarded, and one engine started. The crew found some problem that could not be fixed. The flight was canceled. This run from yhz-bos is very unreliable.

Everything. The crew was so friendly, helpful & smiled. We had an excellent flight getting in earlier.
