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

I almost missed my flight and they helped me out enormously

Business class was very good, one of my best flights

The "on the ground" A/C was not working. It was so hot while waiting to get in the air, a passenger from the rear of the plan declared "I just can't!" and waited in the gangway until time to close the doors. It was miserable. But the crew were champs and had an amazing attitude. I know they were as miserable as we were but didn't let that affect their performance.

The captain announced to the cabin there would be a delay because they observed a "cut" on a tire during precheck that needed to be cleared by maintenance. We were delayed during this inspection and allowed to proceed after maintenance "measured the cut and decided it was acceptable". My complaint is not about the delay or due diligence. I wish the captain had been more generic when making his announcement. I was a nervous wreck all the way to Charlotte worried that we would have a blowout when landing!

The SFO Lounge crew were amazing. The bartender Faris was great. Thanks!

The flight was on time and the landing was very smooth. The crew and flight attendants were all very friendly and professional.

Very good I can’t complain one bit. Thank you American Airlines for making my flight enjoyable and safe!

American Airlines is a miserable experience. It is predictably miserable, in the sense that every time I fly American, I brace myself for the certainty that it will be unpleasant and uncomfortable. But it is unpredictable in the sense that I never know if the flight will be on time or delayed nine hours (both happened to me this week). I never know if I will be able to sit in the seat that I selected when I purchased the ticket or if I will be told by Customer Service (!!!) that I must relocate from first class to a seat in the back of the aircraft with no explanation (both happened to me this week). Will the food be frozen and half defrosted, or scalding hot? Will the drinks be warm? Will the flight attendants be surly and mean? Will the toilets be cramped and foul? Will the seats be narrow and uncomfortable? Will there be a real electric outlet at the seat, or just an unreliable USB-2 port? Will there be enough seats in the boarding lounge or just a few? Will the boarding process be smooth and efficient, or will the gate agents mess it up and delay it needlessly for 30 or 40 minutes? Will the catering and cleaning crew be prompt or will they take an extra 30 minutes? Will the brakes on the aircraft work properly, or will the pilot delay takeoff for four hours while the ground crew attends to what can only be described as routine maintenance that should have been done the night before? I've eexperienced every one of these unpleasant things this year, 2026. The only thing I can reliably count on is that American will find a new way to make the experience of flying as miserable as they possibly can.

Flight was fine, but not having WiFi was a major negative

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.
