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

by the time they got to our row, they were out of some of the food options. games and movies were great but maybe more game options like tetris or pac man would be great

Great as usual, some delays but well communicated and made up for in the air

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.

Business class points redemption - good value for points paid, dubious value if out of your own pocket, domestic class business product okay for this length of flight. The flight left and arrived on time, crew were good, aircraft was a bit old and tired, but still miles ahead of their competitors in Virgin and Jetstar.

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.
