Airline reviews

The boarding process was straightforward. One pertinent observation regarding all boarding procedures is that if an individual requires assistance or possesses a special status and is part of preboarding, it is advisable to limit the number of passengers who can preboard with them, rather than the entire, sometimes large, companion groups. The seats are uncomfortable, and the entertainment options are significantly inferior compared to other airlines. During the snack service, I requested an additional bag of snacks, but my request was denied. Initially, the flight attendant agreed to my request.becoming a strange accurate moment. The flight duration was four hours.

I had a cancelled flight because of technical issues going to my destination, and a delayed flight coming home. All told it wasn’t a total bust.

During landing. 2 crew members passed 3 times by my lane and didn't notice that people in front of us had their site to the furthermore reclined... That was uncomfortable and could have been dangerous.

Seats are uncomfortable. This has been a trend in the industry for decades. Trying to fit more seats on each plane to increase profits at the expense of the passenger.

It’s always a great time flying with united airlines.

We got delayed three hours and nobody thought to have the bathroom fixed while we were sitting waiting to board? took a full hour to have maintenance come and check it off. Had to shut the bathroom down twice so that the pilots could go to the bathroom. Everyone missed their connections.

Women boarding passengers at the gate was absolutely rude and disrespectful of passengers. The flight attendant was absolutely delightful! Smiling and connected with the passengers. So happy. The seats are cramped and uncomfortable but I guess that’s just the way it is Communication regarding flight was excellent

As great a red-eye flight as red-eye flights can be.

Both of my flights arrived early and check in process was smooth

Everything was on time Will use united again for sure

When I booked my flight a month ago - I selected a seat. That seat was NOT the one I ended up with when I checked into my flight the day before. This is the second time this has occurred. So, I checked my next flight on Wednesday and Thursday and no seat was assigned. Poor, very poor customer service.

The staff and service on American Airlines were truly outstanding. I had requested wheelchair assistance for my mother due to her knee issues, and the team went above and beyond every step of the way—from boarding in Boston to our arrival in Chicago. Their care, professionalism, and attentiveness made the entire experience smooth and stress-free. I’m very grateful for the support they provided.

Incredibly delayed. First delay was due to plane coming in being late. Resulted in 30 minute delay. Boarded and then had multiple mechanical issues. Was on plane for an hour until they told people they could get off if they wanted but couldn't come back. Then gate agent rushed in and said they had lost control of who went off and we would all have to deplane and then get back on. They said flight had not been cancelled. Then while sitting waiting to board again they announced it would take two hours to get new plane and to wait at new gate. New plane arrived, reboarded only to find out that pilots had timed out. Waited for new pilots. In that time one of the flight attendants timed out. Never received food or water while waiting. Was confusing mess as to what was happening. Even flight attendants and gate agents were getting frustrated. Almost 6 hours delayed. Called American to received flight credit but can't get anywhere as Kayak reservation and don't have a ticket number. Reached out to Kayak but never heard back.

American flight was diverted and delayed but app didn’t show that information so I wasn’t able to change my connection until the last min.

Wifi was spotty. Tray table was very dirty when I sat down.

Very disappointing. Flight was delayed by 1.5 hours and food options are very underwhelming even for first class seats (same food given to economy seats)

Was not able to do a online check-in because the American Airlines system doesn't store our visa or other passport information, allowing us to have a trouble-free check-in. We were forced to have to check-in at the counter which Changes are upgrade status given that we were not able to check in much earlier.

The plane was very creaky and lots of ringing. Plane was dirty and dingy. I couldn't hear the captain's announcements from the flight deck. Not sure if it was the captain or the audio equipment, but good thing there wasn't an emergency where we needed clear instructions. The overhead compartments were clearly full, but the flight crew allowed people to stand in the back with their carry on luggage. Then after everyone boarded, they had to go to the front to gate check their luggage because there was no room for their bags and then they returned to their seats...such a waste of time when clearly the overhead compartments were full when they originally boarded.

The new planes (American Eagle) are beautiful and especially comfortable. The flight attendants are consistently professional and courteous. And, while it may seem inconsequential, the new liquid tube of coffee creamer—in contrast to the powdered coffee creamer—makes all the difference in a cup of coffee.

Cleared standby and gave up my seat. Terrible policy and boarding experience
