Everything was great except for the boarding process. Everyone is lining up all at the same time and it’s hard to tell between the groups as they are way too large.

Everything was great except for the boarding process. Everyone is lining up all at the same time and it’s hard to tell between the groups as they are way too large.

Very old flight - time to retire it for newer airplanes

2+ hours delayed Outlet in row 12 did not work Tv monitors did not work Lights kept off the entire flight for at 5pm-7pm flight

Do not like the size of the overhead bin. I think staff should monitor the size of suitcases that are being carried on by passengers to ensure they meet the size requirement.

Everything except the food and entertainment. It was a great experience though

Seated dude next to me even though lots of empty rows. But main thing was we sat on the tarmac after landing for 30 minutes because of, in the words of the dude who sat next to me, “operational incompetence”. We got changing directions about where to pick up gate checked bags. Pilot and flight attendant were awesome though.

Delayed, toilets did not flush, pilot parked to far away from Gate

Check-in, boarding and the flight from Phoenix to Houston was quick and easy. The flight from Houston to Shreveport was delayed 5 hours. It was frustrating but I think United handled it the best they could.

The staff was hospitable and professional. The seat had a bit of wear. The winner shade was stuck 1/4 open. I received the best of both worlds. The morning sun was able to come in and blind the screen i was trying to use while at the same time it was too low to look out and enjoy the view. Rather embarrassing for a 1st class ticket.

United is an incompetent airline. They parked the plane on the tarmac for an hour after arriving because they “didn’t have a gate available” it was actually some sort of lie because as we de planed there were approximately 9 open and manned and empty gates that we walked past. Many people on the flight missed connections for the hour long sit on the tarmac. Utterly baffling and incompetent behavior from United flight ops.

Massimo, flight attendant was very authentic, attentive - wonderful. Food/wrap was just okay.

Worst experience ever. Flight could not land in Charlotte for what we were told was a ground stop. Had to be diverted to Raleigh to refuel. Strangely during ground stop, our connecting flight had no issue taking off on time causing us to miss our flight. We were told there were no other flights that day to our final destination and that two days out was the next one. The only flights to get us there were from Chicago the next morning. Completely opposite direction but it was a direct flight. So we get flown to Chicago and have to find a hotel in our own dime. The flight in the morning was also delayed. Thankfully only a short time. The non too of all this, our luggage did not arrive by the time we were there. Communication was terrible, through the entire trip. Complete incompetence. Will never fly American again.

I am an AA flyer for a very long time... AA has yet to disappoint.

Arriving plane went to wrong gate. Flight Attendant was late. Was in no Hurry when he arrived. Flight was fine. Plane had to wait 20 minutes to get assigned a gate due to designated gate tied up. barely connected.. Boarded extremely late on final leg of trip.

See prior comment about how Kayak mishandled my reservation and delayed my arrival by 6 hours.

The flight was fine, once we got underway. It was more than hour delayed

The flight was significantly delayed for 6.5 hours because of snow. There was no communication once the plane returned to the gate regarding when the flight would resume. Other flights were departing while our flight was being unloaded for reasons unknown. Our flight also seemed out of the queue regarding further deicing, refueling, and waiting to Taxi to the runway.

Generally good. Flight left on time and the seats are comfortable. Plenty of space in front if you in you choose a comfort plus seat, completely worth spending the extra money given the amount of hours the flight lasts. The food tastes good but I would say it’s a the amount is too little. The crew was friendly and efficient. There was a some turbulence at different points into the flight. American Airlines has good deals to NZ if you book with plenty of time before you plan on going.

I am very appreciative of the help provided to me by Dennis and Whitney. I had lost my phone at EWR airport and they were very kind in assisting me. This included advice on how to file a report and also helping me connect with family. The pilot was also great about keeping passengers updated on the flight progress with regular communications over the system.

The screens were inoperable for movies and such, but everything else was just fine
