Great entertainment options on the screen. uSB A and C chargers. Free WiFi! Crew were excellent.

Service was excellent and they’re very helpful and nice

Check in crew member was very helpful, nice and excellent service👍

Overall the plane was good and the crew great. The big disappointment was the skycouch. Maybe it would be good if you were a parent with 2 small kids travelling but as a couple it's hopeless. It's impossible for 2 adults to lie down so one ends up sitting. We split our time with one lying and the other sitting. We both got more sleep sitting upright. We will never book one again and don't recommend it to anyone.

Aircon set too high so VERY warm and VERY uncomfortable.

Not a comfortable trip, the seats are not good, and they look old.

Lost my luggage and brought someone else luggage to my airport.

Not entirely positive. It’s frustrating that everything is done through the united app. One of our flight attendants on our trip from San Francisco to MSP continually had trouble hearing people so she flipped her hair into people’s faces

I flew United from San Francisco to Auckland. My connecting flight from Auckland to Christchurch was canceled with no explanation. I was finally told the cancellation was due to fog. Even though it was clear when we landed. I am from San Francisco, I know what fog is! And I didn't see any fog. I was told the next available flight was 7 hours later. Unacceptable, they should have had a flight ready to go as soon as it was deemed safe to take off.

Our original flight was cancelled from SFO to AKL on 6/16/25. So we had to stay overnight at a hotel after a 12-hour layover plus 3-hour delay before the cancellation. Then had to fly to LA and then to AKL the following day losing an entire day of our vacation in NZ, that we can never get back.

This was our second flight using the Delta One class of service. Overall, it’s a good product but for me the POD configuration is a bit constrictive. I am an average size male at 5’ 10” height weighing 190 lbs so it’s not a size thing for me. I’d rather have extra wide seats without the POD walls to be honest.

The airport was reasonably clean. The boarding process reasonably efficient. The cabin crew was efficient, polite but not that friendly. The food quality was unremarkable and the choices were awful . There was either a so so chicken dish or a “ vegetarian “ option which was really cheap carbohydrates drowned in cheese. Signing onto i flight wifi was not straightforward. Overall it was a very average experience

Really low quality food especially for an international flight. The crew also was surprisingly unpleasant except couple of ladies. I know we were not in first class but that’s no reason to treat customers as less.

Nothing special. The crew never went out of their way for anything.

The flight crew was friendly. I tried to adjust my seat online ahead of time but no option existed without additional fees. My friend asked at the gate about a seat change and was able to make it happen. That was great! The flight crew moved a very tall gentleman and his companion which allowed us to have more space which was nice. Overall, good experience. Appreciated the blanket and pillow.

I liked the friendliness of the staff. The cleanliness of all 3 planes.

It was beautiful easy and smooth experience. Thank you. Will definitely get Delta for my next travel.

My flight was extremely cold. I had a jacket and a cover was left in each seat. The cover was extremely thin and I have a disability, fibromyalgia and arthrithis and AC air is the worst. I closed my vent and my husbands vent and it still was frigid. I asked the attendant if I could get another cover and she quickly almost dismissively and totally unconcerned stating, (I quote) (one per chair) and walked off so quickly that I didn't get a chance to explain to her that I literally have adisability. I didnt want to make a seen so I set on that flight for over 5 hours in pain, joints locking up and extremely uncomfortable. When my fibromyalgia flares up my joints not only ache but they will lock up also and it takes me days to get back to my regular self even though I take medication for it. I felt like it would not have hurt anyone at all for her to just give me an extra cover because I'm sure they have all types of medical issues in people that fly every day.

Excellent flight, the planes were newer, they did a nice job with boarding, great service overall.

After I checked in, I realized we had no seat assignment. It said they would be assigned at the gate. This was really frustrating because I usually use a lounge before flights, but I couldn't because I had to be at the gate to ensure we got our seat assignments. The gate agent arrived an hour before the flight left. I was the first one up to ask about seat assignments. She told us to wait for names to be called. Dozens of other passengers were paged, but we were not. Finally, I asked my husband to ask. He went up and was also told to wait. About 10 minutes later, they called for boarding. We still had not been told our seats. We went back to the desk and they were in a panic, saying we actually weren't on that flight. Then they made an announcement telling the stand by passengers to not board (in case we needed their seats). It was so stressful and unprofessional. Finally they gave us our seats. I have no idea what happened and why the two desk agents seemed to have conflicting ideas about our seats, whether we were on that flight etc.

Excellent service. The personal adaptation of menus and the individual timing of service of them is fantastic.

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

Awesome hospitality, awesome staff, awesome food & awesome travel time. Thanks

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.

My baggage is lost. Flight cancelled, Rebooked ticket through long routes. Mental stress, emotional hurt

It never happened. Me flight from Doha to São Paulo was lated and the time of waiting for the luggage arrives when we arrived in São Paulo was about 1 hour and half. So it took a lot of time just waiting the luggage of flight that was already late, consequently we lost the flight to Recife with Latam Airlines and had to go to the Qatar office to arrange another flight to us to Recife, that one with Azul Airlines. It was more 4 hours waiting to this other flight to knows that this other flight was delayed too, total of 5 hours more at the airport to waiting to go home :/

I wish the leg room was better for Economy especially for the outbound flights to India . The outbound flight to US and Qatar was good

My flight was with American Airlines 120. The flight was delayed 3 hours and I missed my connection. When I arrived in Doha, the AA staff told me to call an 800 number to rebook a different flight, which was unacceptable. Eventually a Qatar Air staff member helped rebook me on a flight to Manila, that was 12 hours later. They offered me a hotel and meal voucher which I declined, because I didn’t want to leave the airport. Long story short, I spent 12 hours in the Doha airport waiting for my next flight.

Reason for travelling Tampa to Orlando is to fly Qatar Airline. we end up with American Airline. This was the miserable experience I ever had in my entire travel history. Flight attendants were rude. They hit my knee with the food cart and I was holding ice pack for 2 hours. I still have the pain after a week. WE boarded the flight twice because of the temperature inside the plan.

The food quality sucks. One must starve if they do not eat flesh Or wheat based products Some variety would be expected. The trivial amount of snacks and or food is inhumane

We Left Calgary 1/2 hour late and that made for a tight connection in Denver. After arriving everything was done to help us make our connection. That was a great effort. Thank You United

Efficient all round, very good crew. Short flight so the food, of course, was just snacks

Overall, it was good. I was seating next to a wonderful lady and did not notice how time flew. Thanks

My flight was delayed about 1 1/2 hours in Chicago, but other then that it was a good flight.

The experience was great, the crew was very polite and hospitable. I will definitely make if my go to airlines.

It was all good flight was on time, service was good I enjoyed a few movies and everything was smooth

Efficient, calm when things were delayed and kept us regularly informed of what was happening.

Airbus plane, nice and polite staff, entertainment even as it was a short flight.

Very nice and clean plane. Transit time between flights was tight though

It was crazy, boarded over a hour late from scheduled departure. Then when arrived in BNA issued with getting off the plane…over 1/2 hour. Not looking forward to flying Air Canada, ever again.

Great flight. Only complaint is it took over an hour for my luggage to get to the carousel on the return to LAX That was irritating

The service to/from the airport/plane (wheelchair assistance for my mother in law) was exceptional. The staff was super friendly and courteous. The staff on the plane was also very nice. The food quality could have been better (mashed chicken sandwich).

The flight was great. I like it when airline capitalism give you information. For someone with flight jitters it really helps. And this captain was very cheery and reassuring. I had trouble understanding the head flight attendant because she spoke very fast. But overall staff were very helpful and kind.

1 hour late No hot drinks No restroom in the back of the plane

I did the posting for 45 years. I just retired. I’m the only seat in the plane but didn’t have any phone. It has to be mine so imagine seeing 13 hours on the flat seat with a belt that didn’t close all the rest was OK.

I had wonderful wheelchair assistance through the Montreal airport onto the flight. Air Canada was excellent in this both at the Fredericton airport and the Montreal one where an attendant helped us through customs as well as transport and baggage security.

Flight was cancelled last minute due to Air Canada strike leaving us stranded and having to stressfully find a way home that cost hundreds of dollars in excess cost added to the trip. Having just experienced our mother's funeral service, this was not a good way to end our trip.

They went on strike before time and screwed us big time. Which is not fair. We respect their planned strike but why they went on strike ahead of time ??? Poor garbage management

Premium Economy is best if you can't get upgraded to Business.. Not as good to sleep for red-eye flights, but does the job. More space for your legs and arms.. The food is also better and the service is almost like business.
