Although the flight was delayed the crew and the flight itself were very good. Couldn't fault anything and after the disappointment of being abandoned in the US by BA it was a welcome relief to travel with United

Although the flight was delayed the crew and the flight itself were very good. Couldn't fault anything and after the disappointment of being abandoned in the US by BA it was a welcome relief to travel with United

Survey sent before we actually left. Delay after delay. Now a crew problem.

I love flying with United. Unfortunately, I flew on an older plane with minimal upgraded technology (no Bluetooth functionality or handy charging ports). Otherwise, the flight was great and even arrived early.

They changed my seats after I checked in and I was stressed from the time I saw that information until just before boarding, when the gate attendant fixed it, but it shouldn't have happened. And if it couldn't be prevented, then the people on the phone I spoke with should have done something to help, which they did not, nor did they offer me compensation, just meaningless apologies.

online check in was not available so i had to get to airport extra early. The flight was delayed and my luggage was lost. I had an argument with the person behind me who wanted to keep her bag on the floor and not allow my seat to recline on a 9hr plus flight. So overall, lots and lots of areas for improvement.

Horrific. They missed my connecting flight to San Diego. I didn’t get there until Monday at 9am when I had a mandatory court settlement conference scheduled at 6am since we had parties on the east coast. This caused many issues. All because United apparently forgot to hold the doors open until my flight landed that only had a 10 minute delay. This was the last flight to Southern California. So I couldn’t even rent a car to finish the trip. United cannot be trusted when traveling on specific days and times since weather didn’t have anything to do with the delays.

My flight was delayed a very short period of time but they did not hold my connecting flight to San Diego, also through United. So they closed the doors before we got off our plane. They would only have to help the door open for another five to ten minutes. So I missed a court deadline for a manditory mediation settlement conference for my client. I had to get an associate to be there in person and be on the phone with him relaying what he needs to do the entire time. The court was very upset with me and so was my client. United cannot be trusted.

Very rough getting into denver. my kid threw up it was so rough.

We were given vouchers we couldn’t use with a 5.5 hour delay

Cramped seat even in economy plus seat 10A. Over booked flight, no space for the bags

The flight delay in Dallas created a domino effect that impacted all of the connecting flights. It also increased the number of connections. I missed my flight from Casablanca to Marrakech because of the tight turnaround when landing in Casablanca. . CMN airport was understaffed. Only one person could help while other employees were just watching him. It was an extremely frustrating situation. People were crying and slamming their palms on the counter when speaking to the customer service provider, Allabough (man’s name?). Allabough couldn’t change my flight in the system. simultaneously, I was on the call with America. Airlines customer service rep named Solomon that said he couldn’t change it either. So, I took a ONYA voyages train to from Casablanca to Marrakech to get there on Friday June 26. This was unpredictable trip.

The flight delay in Dallas created a domino effect that impacted all connecting flights, leading to an increase in the number of connections. As a result, I missed my flight from Casablanca to Marrakech due to the tight turnaround when landing in Casablanca. CMN Airport was understaffed; only one employee was available to assist passengers while others just stood by and watched. It was an extremely frustrating situation. Many passengers were crying and banging their hands on the counter while talking to customer service representative Allabough. Unfortunately, Allabough couldn’t change my flight in the system. At the same time, I was on the phone with an American Airlines customer service representative named Solomon, who said he couldn’t make the change either. So, I decided to take an ONYA Voyages train from Casablanca to Marrakech to reach my destination on Friday, June 26. It turned out to be an unpredictable trip.

The flight was fine and the crew awesome. The problem is ORD and AA. Computers went down, ORD fell apart and a 40 min flight turned into a 3 hour trip. Guess the answer is to not try and fly to ORD after noon. But, as I said, crew was awesome and did everything they could to lesson the flight time.

Almost a 6 hour flight and the only food option is a cheese plate… and chips. Also how is it there are no options for texting on American. I’ll be going back to delta and united.

This flight never occurred because AA couldn’t get their act together.

Terrible. Cancelled my original flight. It made getting a boarding pass difficult. The AA employee (in a loud voice, so everyone around could hear) griped at me for not getting a boarding pass 24 hours before. I asked how I was supposed to do that when I had no idea what flight I was going to be on. She said (loudly), “Talk to AA customer service, not me!” I could certainly tell serving customers was not important to her. Our new flight was set to a completely different city. We had to change our rental car, and the price went way up. It took 2-1/2 hours to get checked in. By then our new flight had left. We ended up on stand by and had to split up the family to get to our destination. It cost us the whole first day of the trip. AA needs to employ people who actually care about doing a good job. I suppose those people are getting harder to find, but atleast try.

Am still mad at American airlines. You should know it's us travel nurses who are your customers and you treat us like nonsense it's not ok. American airlines took my money, no refund for whatsoever. A trip that was of 466 and I paid 466 and 833 then they chose for me where to sit and refund my seat choices and gave me expensive seats for 79 USD. Kayak doesn't help at all after booking you are on your own. Skyscanner is better

Bad food, small seats that didn’t recline. I thought I was buying a quantas ticket so I feel like I got scammed

This was a horrible experience. For a first class experience, my chair was held together by 3M tape - and I have a photo. The crew weren’t very attentive, somewhat dismissive and forgot my drink and snack, the chair reclined about 3 inches on a 6-hour cross country flight. I was also not informed that there was no lounge available in Newark airport because of renovations, so all around this was one of the worst experiences and I would actively avoid both American and Alaska Air going forward.

The flight was fine but the 8 hour delay in Chicago was awful - 5 gate changes and repeated delays without an explanation. No vouchers. Nothing.
