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.

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.

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

Economy was much nicer on the Air New Zealand planes.

Couldn’t request a vegan meal somehow but I noticed other people getting them

They announced food service but then never came around. We also couldn’t land so kept trying to get to runway and then had to come up and go around happened like 3 times and cause the child next to me to start throwing up

Great food and good entertainment options for the long flight.

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.

Good check in and helpful staff. Delayed for 1 hour. Took about 45 Mins to get baggage’s at DFW . Food was average ( Hindu meal ) . Overall it was good experience

When I originally booked this flight, I was expecting to travel on Qantas. When the itinerary changed and the long-haul segment was operated by American Airlines, we were disappointed but remained open-minded. Unfortunately, the overall service experience fell far short of expectations. This was a long-haul international flight. Getting up periodically to use the restroom or stretch is inevitable, especially on flights of this duration. However, each time we stood up, we felt as though we were inconveniencing the crew. The tone and body language often suggested that we were in the way or disrupting something simply by moving about the cabin. As a result, I avoided getting up as often as I needed to and was physically very sore upon arrival. Meal service was similarly impersonal. The options were presented in single words “beef or veggie,” “pasta or beef” without any description of what was actually being served. There was little engagement or courtesy beyond that. Even simple expressions of gratitude were often not acknowledged. I am accustomed to no-frills travel and do not expect luxury. What was disappointing was not the absence of extras, but the absence of basic warmth and professionalism. On a long-haul international flight, small moments of courtesy and humanity make a significant difference. In this case, the experience felt transactional and dismissive rather than welcoming. I hope this feedback is taken constructively, as there is a meaningful difference between efficient service and indifferent service.

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

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

I tried to check in online but was unable to do so. I stood in line for nearly two hours to check in. American Airlines was understaffed. When I finally got to the kiosk to check in, I was still unable to check in. No AA staff was available to help. Finally one of the airport security agents who was helping passengers became of lack of AA Staff told me: “I think the reason you can’t check in is that you are starting your name with an upper case letter when you write it. Just write it with all lower case letters.” That did allow me to check in. HOW COULD ANYONE POSSIBLY KNOW THAT IF THEY USE AN INITIAL UPPER CASE LETTER TO SPELL THEIR OWN NAME, AA WOULD NOT ALLOW THEM TO CHECK IN?????? Then I had to wait in line over half an hour again to drop off my baggage. Although I arrived at the airport 3 hours early, by the time I got to the gate, they had already started boarding.

Friendly staff, surprisingly good premium economy seats allowing good sleep/ snooze opportunity and very good menu.

The service was excellent. The quarters were a little cramped in Economy, and we had to exist there for 18 hours.

Food was great. Customer Service not so much! Flight Delays.

Entertainment center did not work and no electric available at seat for 11 hour flight. Didn’t have access to overhead light or call button. Food was tasteless and had a high salt (27 %) of recommended daily salt intake

What would be infinitely better if for Kayak to not offer this flight as if it was completely different airlines rather than United and then filtering me through some creepy discount site.

Our flight gor canceled and there was no one to help us but told us to scan the qr code and fill the forms on-line. Very poor service especially we are tourists traveling to Washington DC for the 1st time.

Our flight was great with an unexpected upgrade. However, four days into our travel we are still without a piece of luggage. The bag tracker has not been accurate, the airline is not communicating with me or the luggage delivery service and no one is willing to take responsibility or guarantee any kind of support or reimbursement. Unfortunately, we do not have the option to easily shop to replace items as we are currently on a cruise. I have been very disappointed by United Airlines response.

The flight was canceled. I couldn't get on another flight. Meal voucher wouldn't work. The whole experience was a clusterfuck.

Uncomfortable plastic seats even in premium economy. No free wifi. Even paid wifi was spotty to nonexistent. Bad food. Much worse than economy on foreign carriers like Qantas.

It was good but only meal served is very less. Meantime good to add rice and chicken in one of meal

I found the staff to not be very attentive at all. When paying for Business Class you expect a certain type of service and that was not found. They were almost rude even

Great. Food going from Australia to the US was better than other way around, but still needs improvement in terms of quality and quantity!!!

Due to a cancelled flight the day before this flight only had 44 people. Best flight ever on international route. Food getting better. Can United provide fruit ex apples and bananas for snacks? Crew fantastic.

On time departure & early arrival. Made a long day much better.

Like all planes recently, entertainment is achieved by giving the patron free WiFi and letting them stream shows via the screen on a phone or tablet.

Crew and agents misguiding on tight connections, and lack of connecting crew looking for inbound planes. A very avoidable missed connection as a result.

My flight was 4 hours delayed on departure at 6a causing me to miss my connection at DCA. I had to scramble to find a seat home on a later flight and instead of an exit seat, I was in row 30 on a flight getting me home 5 hours later than planned. The AA team on the ground did a fine job. AA continues to run the airline like the passengers are cargo.

American Airlines changed are gate no fewer than four times. Walking back and forth from one concourse to another was exhausting, especially after all the flight delays.

The plane was comfortable but the crew wasn’t friendly.

I have been flying with American most of my professional career. But the airline seems tired and becoming more and more subpar with older planes than other airlines, dirtier and less comfortable seating, and less and less amenities. Their WiFi seldom works and their food is becoming more and more mediocre. How do you fly from LAX to PHL with only being offered one drink and as a platinum customer. I am exploring delta here on out for more of my flying.

American Airlines canceled the flight twice and was unable to facilitate a change of city for us after our travel plans became affected. We lost alot of money due to this and it seems like the airline was trying their best not to facilitate this. Mind you, I am a very loyal member.

Flight was a delayed a few minutes but nothing crazy, everything went extremely well

Our seats were better than i had anticipated. They provided nice pillows and blankets as well as a kit with ear plugs, sleep mask and headphones which made the long haul flight better. Their food selection and service was good. I appreciated that they came through the cabin with water a few times. We were ahead of schedule which was nice!

The flight was good. My luggage didn’t land with me when I arrived in Columbus. So grateful I was able to get my luggage back within the 2 hours😍👍.

The flight attendants were not very nice. No smiles On my return trip I was charged for one bag $83.30 although I had purchased the flight including one piece of luggage. Can this be refunded to me? Thank you!

Full compliments to Captain for all four landing. Crew could be more polite and nice.

So smooth and easy! From boarding to arriving, we are very happy with our experience on air Canada.

There was a long delay on tarmac. The pilot kept us informed. The flight stewards were not entertaining or comforting. During the flight we received minimal service. Several food choices for purchase were not available at our seating of row 52. Only twice were we offered water for hydration. A half hour before landing teh pilot acknowledged that some passengers with connecting flights should tell flight stewards and they would help.. We had a connecting flight thand at should have had a 2+ hour layover and now would be less than 1 hour from departure. The flight attendant told us not to worry.. plenty of time. We did not get off the plane until after 6 o'clock. We are seniors (ages 74 and 72 ) and had to walk the length of the terminal to go thru customs and the length of the next terminal to departure gate for 6:30 a boarding call. We ran and were breathing hard and reached the departure gate by 6:50. We rate the flight stewards negatively...the pilot did his best.

It was very bad travelling with air canada the people working at check in bagages was very bad person any way I pay to much many to get good flights but it’s not

Air Canada switched my connecting flight to Alaska airlines without any communication to me. The process of finding this out, needing to leave one portion of the airport for the next and what i should have done with my luggage was not communicated to me at all. Even the Air Canada agent that noticed the airline switch at the terminal did not explain this process to me. In doing so my luggage did not arrive with me. The delay to create a claim too 2 hours.

Food was great. Staff was great. I would have liked to see more in flight shopping - they went by so fast I missed it. I would have liked more variety in tv shows but overall flight was great. The staff made all the difference.

The bathroom I used could have been cleaner and tidier. Didn't look like it was kept very well. The staff were super helpful. There was an issue with my screen, and they rebooted it for me. They were also great at dishing out our meals, and cleaning up after.

The seats were very nice. The flight attendants were obnoxious and rude. I felt that if I asked for something they would bite my head off! When I did ask for something, they said they would do it after they finished what they were doing, but never did. Horrible. Check in at business class took way too long.
