I had only one problem. The temperature on the flight was too COLD. I froze throughout the flight. I thought it might be only my problem but when I went to the restroom during the flight, I saw several people huddling in their jackets. A couple had their winter coats on and I was jealous since I had only a very light jacket.

Our flight was delayed by over 4 hours due to a maintenance issue. They announced a new plane was on the way. We were given a $12 food voucher ( airport food is quite expensive You can’t even by a water and a small snack for 12:00. 4 hours later we boarded and landed in Atlanta at 10:20 ish pm. Of course we missed our connection and we were given a hotel voucher and another food voucher ! We didn’t make it home until 11:00 the next day ! Unacceptable

Fast, lovely scenery, great info on the Delta flight screen about landmarks we were flying over. Great landing!

Delta needs to step its game up get a more reliable internet service. Internet service was non-existent for this flight.

The crew was not very visible. This might be a good thing for people who wanted to sleep but seemed odd when compared to the Atlantic crossing where they are more present in the cabin. The Food (beef) was not good. Tough and tasteless. Would love to see more choices on a long flight like that.

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.

The crew on this leg continue to be extremely helpful with my wife’s mobility issues. They also came by many many times to ensure we were comfortable and had drink some food.

The Pilot was one of the best I've had, very informative about turbulence and got us to our destination early

I liked the cleanness in the bathroom and good crew on board and at boarding gates. There was no Hindi (Bollywood) movies. The entertainment can be improved as it is one of the worst one I saw when I compared it with other airlines. The Mumbai to Amsterdam flight did not have any food for my family which does not contain eggs in it though we have selected “Hindu Asian vegetarian meal”

Friendly boarding crew. Better could have been a bit more substantial food for this 3 plus hour flight.

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.

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.

Had a one hour delay due to mechanical issue. I didn’t think I’d be able to make my connecting flight, but they waited for me and greeted me when I arrived to help things run smooth.

Staff were good. My seat was in need of repair, but for a short flight was not problematic. Usual basic snack and drink setup that you'll find on any US carrier. Over, a decent, basic flight.

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

I will never book a flight through Cheap fare. They booked me from Portland Main . And would not give me a refund, so I bought 2 tickets one for 299. From Portland Main to ORD. Then I had to buy a ticket from Oregon PDX to ORD that was another 440. So Just so you know they even told me it was there fault but no refund. Bad bussniess. I did inform United but they said they couldn't help me due to the fact I booked through Cheap Tickets. Never again. And I'm spreding the word. I let everyone know at my 50th class reunion

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

Pilot Erika DeLong made us feel safe and at ease in a frankly scary time to be flying. Her warm smile and greeting and excellent command of the aircraft in foggy bumpy weather helped us all to calm our nerves and get us home safely.

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

Not enough room between rows and food was gross. $160 baggage charge?! Never again.

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.

they were super helpful. Agents at the desk got me on an earlier flight and I was able to get home several hours earlier.

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.
