Service and the plane itself were terrific, but the extensive delays both before we left and after were a real pain.

Service and the plane itself were terrific, but the extensive delays both before we left and after were a real pain.

It was good and there is nothing to complain about .

The seats were narrower compare to other airlines traveling to Asia, which makes them uncomfortable after 6 hours The plane was worn, my tray table wasn’t level, You had to pay for WiFi and no Bluetooth option to use your own headphones. The crew was excellent in servicing the food and drinks. However I felt they needed some extra hands to serve the two sections of economy at the same time. They run out of one of the food option as they got to the rear section of the plane. Having travel on other Asian airlines during this trip; American Airlines can learn a bit from them, but I wonder if their service is geared towards a clientele that has become accustomed to not expect to much from an airline.

It was just a short flight. The crew was nice. No major issue.

Overall, it was ok. The attendants are nice. It was a short flight, and I did not use the restrooms. What I was frustrated was the check-in. I was to fly from ATL to Chicago (American) then change to Japan Airline to go to Japan. I checked in, but I only got a boarding pass for the flight from Atlanta to Chicago. It said I would need to check in for a flight to Japan on Japan Airline site. When I tried to check in on JAL website, it said I need to check in American... It was very confusing.

The crew was great, food was good. My concern is about the plane itself. It wasn't super clean, and during the landing process (after attendants had to take their seats) the air conditioning vent above my daughter's head started leaking a lot of water. It leaked for about 30 minutes, until we landed. I let the attendant know about the leak as we were getting off the plane, and she was very kind about saying she'd look into it. Given concerns about hygiene on planes, plus the fact that my daughter had to hold the blanket over her for 30 minutes to avoid getting soaked, that was not a great situation.

Absolutely WORST experience I’ve ever hard NEVER buy your airline ticket through a third party website, especially this one. Basically stole $1300 from me and has the WORST policy taking a WEEK to change a name on the reservation? A complete joke of a company.

There was a problem with the maintenance so missed the flight from las vegas to L.A and then L.A to Narita with japan airlines. They took care of the problem by rebooked with cathay pacific airways.

I paid for premium and it’s wasn’t what I was told I would be getting. Food wasn’t good. Should be able to pick and not be served items you dislike. Very little leg room.

I am trying to select a seat during booking but it respond that set assigment will be given during check in, and the seat assignment they give is in the middle seat and 2 row from the rest rooms, i am the person who pee a lot in this case I disturb so much the person beside me ,this trip is from Haneda to Texas, the trip from Texas to Cvg is a much better because its a smaller plane few passenger

It was ok, but not what it was like 20 years ago

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.

Over 5 hour delay with minimal updates or ability to standby for alternative flights. During boarding and 1 hr+ wait for takeoff, seats were drenched w water from air conditioning condensation and always leftover crumbs on carpet and seats

I flew from Barcelona to Chicago on UA yesterday. The flight was on time, the pilots did a great job and the flight attendants were super nice. All of them. Also food was good, and the drinks, including wine were served a few times during our flight. I highly recommend this airline.

Boarded early, left early, arrived 40 mins early! A win win for me!

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

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😍👍.

gave me complimentary food as the flight was not full and was attentive to my needs

It was a nice and smooth trip. Gave a friendly environment throughout the journey.

Meal and drink service was good. Old plane with old business class seats were quite disappointing

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.
