Unfortunately I was stuck next to someone who should have purchased 2 seats instead of taking up their space and mine. I couldn’t move the entire 3+ hour flight. Very uncomfortable flight.

Unfortunately I was stuck next to someone who should have purchased 2 seats instead of taking up their space and mine. I couldn’t move the entire 3+ hour flight. Very uncomfortable flight.

Only one side of the heafphone jack work. Crew was friendly and helpful.

Great. Flight departed early and arrived early. Deplaning and baggage claim ww were quick.

They separated our seats and moved us to the back of the plane. Hundreds of dollars and thousands of miles used and this was my platinum member experience.

Since it wasn’t a Delta flight, I was not able to sit with my group and there was no entertainment.

Three adults, three children. They did not give us seats together. Two seats together, in row 23, one in 13, one in 14, one in 10, and one in 17. When we got on the plane, the crew tried to ask people to move but basically threw up their hands. One person moved so we had two pairs of seats together. The 1.5 year old sat on a parent's lap (despite having paid for his own seat).

the fight attendants were great and i appreciated that they had season 1 of The Wire from HBO as a viewing option

AC barely worked on a 50 minute flight. It was very warm the whole flight. Flight was very bumpy and hard landing.

Got on the plane and then needed to deboard the plane because they didn’t have any pilots?

The flight was canceled two hours before departure, it took over five hours to rebook us on another flight.

Smooth boarding and friendly crew. Unfortunately as soon as we boarded the unit that provides air circulation failed. The pilot informed us and requested maintenance technicians to check it out. The plane became uncomfortably warm without any fresh air coming in. Plus the repair delayed our departure. I am glad the maintenance crew were able to fix the problem. I also was without use of my tv monitor for the first 1/3rd of the trip.

Communication with the customer and stay is important. Staff off with a minor inconvenience but it worked out of course. Also this was a very old Mint Class plane. They snuck this one in on us. The updated aircraft are much better.

The flight itself was fine, but the boarding process was extremely frustrating. There is no one scanning boarding passes - passengers just scan themselves and enter the jetway. By the time my husband and I got on the plane and were halfway to our seats they determined there were too many bags on the plane and everything at that point needed to be checked. This created a lot of unnecessary chaos. They should have alerted people before getting on the plane that they would need to start checking bags instead of waiting until people were already on the plane.

The best flight I’ve had in a while. The plane was like 25% capacity, if that. Smoothest boarding and deplaning process I’ve ever experienced. Wish all flights were this smooth.

I like their airplanes because they have plenty of legroom in their seats they always work with me if I have a change of plans on my tickets courteous and I always feel safe flying with them.

The flights are back on time and everything else runs perfectly.

The WiFi stopped working early on in the flight. No audio from entertainment system.

They announced at the last minute that international travelers had to checkin at counter. This created a long line and unnecessary stress.

After 14 hour delaybwith departure time changed 9 times then announcing the flight was canceled. Another later announcement said the cancelation was in error. Also after paying a higher fare to leave in the afternoon then departing at 4am was not right.

I cannot say this enough, I NEVER BOARDED OR HAVE HAD ANY TRAVEL IN THE PAST YEAR. However your app says ive been traveling a lot lately. GET REAL HUMANS TO GIVE CUSTOMER SUPPORT.

Staff was generally seeming stressed out and was a bit rude and slow. Plane left late. Pilot was very well-spoken.

Cabin was pitch black, even during meal service. The reading lights for seat 2E/F did not work, and seat 2E did not recline.

The seat seemed roomy, the service was good, everything was fine.

Was realllly smooth. It was delayed but we were well informed.

The senior flight attendants were amazing. Totally different vibe from other carriers. Easy 10 hour flight in Business Class. Great food. Good humor as well.

Delayed by 2.5hrs any longer and they would’ve had to honour their own policy for breaking their own rules and regs. Not cool, especially when I have an infant child that needs to stay on a routine and they get schedules.

The width of the chair is very small. Not comfortable at all.

Flight delayed over three hours. Arrived into SFO during rush hour and what would have been a one hour drive home took more than 2 hours. Very poor UNITED AIRLINES!!

I found that it seems that the space for personal bags or luggage is not enough( the cabinets for personal bags or luggage over the seats) .

service was slow and at times there was no service at all in premium plus seats. they do not care about people in premium plus

Great thanks - a whole row to myself. Good food but film selection not great.

My boarding pass wouldn't pull up in the app very easily and had to really dig through my email. That caused a delay in TSA..

I liked the duration speed while in the air but that is is for positive things to say. The service was over 3 hours late, staff not very friendly (probably because they were also late to the destination), uncomfortable seats and disappointing food options

RE Food: Wish there was a choice for No Rating. Flew from Honolulu to Los Angeles on a Red-Eye flight (11:00 pm to 7:30 am). Other than a package of cookies with a beverage choice offered soon after take-off, and a beverage choice shortly before landing, no other food choices were offered. Everyone slept or rested for most of the trip. Nothing to rate. RE Entertainment: Everyone was sleeping most of the flight. Only saw one passenger watch about 30 minutes of entertainment on his iPad. I never attempted to access any entertainment options.

Baby cried a lot. Nothing anyone could do about it. Just part of flying.

The boarding process was such a chaos with everyone crowding at the gates. There was no structure. The onboard crew were fantastic and very good.

For coast to coast travel the A321 and even the NEO, even in first class will never be excellent. That would take a B787 or 777 to accomplish.

The flight crew was fantastic! Which the seats had a small TV.

The foot ottoman cushion was missing on my business class seat.. the hydraulics is on its last leg & seat cushions do not have support or paddling. Heavily dented by butts

I have been flying with American most of my professional career. But the airline seems tired and becoming more and more subpar with older planes than other airlines, dirtier and less comfortable seating, and less and less amenities. Their WiFi seldom works and their food is becoming more and more mediocre. How do you fly from LAX to PHL with only being offered one drink and as a platinum customer. I am exploring delta here on out for more of my flying.
