The flight from Chicago to Orlando was delayed inordinately. My whole journey from Lansing to MCO took 9.5 hours is just annoying and frustrating. We can understand the delays may be beyond their control, but overall the journey was so much waiting until reached to MCO. This is NOT the first time for me - but at least 80% of the time in this route. I barely remember reaching places on time.

I was truly shocked at how poor this flight went. The crew was not friendly during the checking process. The asked for people to gate check and were rude about it. They didn't handle my luggage with care. When I got to my seat I noticed a large section of the ceiling vent area was, no joke, TAPED TOGETHER WITH CLEAR PACKING TAPE! To add insult to injury, the back rest button was disabled on my seat and all the seats I could see. The wifi, never connected for me, despite troubleshooting it for a while. I did everything from restarting my wifi/phone to forgetting the network and restarting the app. But that didn't stop the mandatory 2 ads from playing every single time. Even the bags took over 45 mins to arrive at the carousel. Everything about this flight was a flop and I am beginning to notice that some of these events are becoming a trend. Perhaps it's time I switch loyalty programs.

Fliy was late missed my connection ,. I had to find altery transportation.

It would be helpful to be able to download an eticket from either American airlines or Cathay Pacific; not just Cathay Pacific.

Food is what you expect on a plane. Nothing gluten free. But that is expected. Drinks, apple juice, was fine. Seat, what I expected. Fine.

I'm not sure American is capable of on-time arrivals and departures. When you land at ORD, you almost always get held on the tarmac because your gate is still occupied. I may have missed my connection, but that ended up up being significantly delayed as well. Once again, I finally got home well after midnight.

I liked the humor of the captain and crew on the flight from Flagstaff to Dallas. They were humorous.

Delayed delayed delayed and no offer for food or vouchers

Turn on the heat. Flight was way too cold from Arizona to Chicago.

Overall pleasant was delayed and caused transportation issue when landing
