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

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

No internet on flight, which makes log travels really hard.

My flight from Dallas to Sydney was cancelled. My entire trip was rerouted to include the following: Hartford to Washington DC Washington DC to JFK JFK to Auckland Auckland to Christchurch I paid for an aisle seat on the flight to Auckland and was asked if I would take a window seat to accommodate a family. The agent at the podium failed to mention that the family had a 3 month old baby and that a bassinet would be used during the 16 hour flight. The only way I could get out of my seat was to crawl under the bassinet of the sleeping baby. I think it is wrong that I was no given the choice to sit in another seat, that the agent knew what she was doing and chose to not properly disclose my seating arrangement. Terrible treatment.

they ran out of fruit for breakfast and so I just had a yogurt instead. other than that the flight was good

One of the best Qantas business flights I've had. Quality product

Poor! This flight was delayed 14 hours. There was no assistance in helping customers find other routes to their destination, nor any other kind of support. It was a chaotic experience. I'm not likely to fly with AA going forward.

We were upgraded and after just a short delay in attending to a safety check we were on our way. Would definately fly Qantas International on their Dreamliner again.

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.

Traditional economy class. Not a full flight so spare seats. Food and drinks were good

Their aircraft are old and amenities lack way behind other international carriers leaving from BNE. Even in economy

Short flight but an "eager to help" crew made the journey more enjoyable!

Not enough veg food available for passengers. I actually did not get the veg food and was told it was over, and I starved the entire flight duration.

Flight was delayed only slightly before takeoff due to traffic control. However, the flight arrived early to ORD. Good flight. United has been very reliable for me.

Flight left on time. Boarding was easy. Arrived to EWR 30 mins early. Luggage was deplaned in good time. Overall a very good experience.

Flight from Rome to SFO was excellent compared To our flight to Europe from SFO. The food was much tastier. You can see how UNITED is skimping, though. Instead of getting something mid flight you had to ask for it. It was not automatically served. There was a cookie at the end of the arrival meal, for example that tasted like it just came out of a box. They used to serve a little container of nuts, now … a tiny container of nuts, mixed with pretzels. This was business class that you really have to pay for! But this is minor complaints compared to the overall. My major complaint is the position of the even numbered seats by the windows. You have to turn around to see your window & the positioning as some other controls are harder to get at. This is compared to the odd number seat that are perfectly aligned.

The person I bought the ticket for didn’t make the flight.

Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.

Another delayed flight. When the delays exceed the duration of the flight, it’s a problem.

Excellent flight. Smooth, efficient boarding. Quick flight. Arrived early at STL.

After boarding the plane in Chicago, the passengers were told that there was a technical problem with the plane. Passengers remained on the plane as they tried to fix the problem. After what was probably an hour passengers were told that there was a need to change planes as the problem was not solved. Passengers disembarked and boarded another plane. After taxing to the runway and waiting for takeoff, passengers were told that owing to the thunderstorm the flight was unable to take off but would try and reroute. After some time passengers were told there wasn't enough fuel for the new route and the plane had to return to the gate for additional fuel. after another log delay the flight got underway. On the plane there was food, drinks, ice or entertainment. We were a glass of water, which appeared rationed. Flight arrived about 5 hours late. The pilot was fantastic and communicated with the passengers throughout the ordeal.
