It was a short, comfortable flight. It did leave an hour late due to the pilot having to be replaced (family emergency) but that didn’t inconvenience myself & my friend. The situation was explained, eventually.

It was a short, comfortable flight. It did leave an hour late due to the pilot having to be replaced (family emergency) but that didn’t inconvenience myself & my friend. The situation was explained, eventually.

The seats were very uncomfortable. I paid for the front economy. i swear they added a row of seats in there. It was so tight, that I could measure the distance between my seat and the one in front from my elbow to the tips of my fingers plus six inches. The seat cushion was completely worn out. The dinner was very good. Thank you for having a vegetarian option as a standard. But breakfast was nothing but sugar. that's not food. The crew was crabby and rude, especially in regards to coming to the back gallery. And the entertainment choice: why would you put violent movies on the choice? the Godfather? Some movies with black women being beaten over the head with clubs? What the heck? You know that when there is a movie on a plane, everyone gets to watch it. Why choose the most violent titles possible? The total number of movies were very limited, and the television, even more so. No games were available on the set. The wellness section was nice, thank you. I appreciated a galley in the middle where I could stand. The seats were unbearable.

UA594 was delayed multiple times. I ended up getting picked up so I can make it in time for work 6AM on Monday, 7/6/2026

Boarded from a very small gate at LAX. Staff at gate had us line up, then waited 25 minutes to board without a word of explanation. Plane arrived on time then waited 20 minutes for a plane to vacate our gate. Majority of bags arrived after 15 minutes but it took an hour for a small number of remaining bags to be off-loaded despite my “priority” bag tag.

Excellent communication from the staff. We actually arrived early. Very friendly and professional staff.

Great staff. Clean plane, but we were delayed for more than an hour due to maintenance issues and had to board another plane.

I was very disappointed with my experience at the United Airlines baggage check. The representative was rude and unhelpful. I was required to remove approximately 1.5 pounds from my two checked bags, even though it was a very small amount over the limit. The interaction was unnecessarily unpleasant, and I expected much better customer service. I hope United will review this incident and provide additional customer service training to its staff.

No extra snacks were available. Meals quality is terrible. Crew was not friendly.

Lost one piece of luggage even though I checked in 2.5 hours before the flight

My experience on this United Airlines flight was highly uncomfortable, primarily due to two issues: Cabin Temperature: The temperature on the Boeing 737 MAX 8 was unacceptably high, feeling consistently around 80 degrees throughout the flight. This made sleeping impossible and significantly detracted from the experience. Seating Arrangement: Being stuck in a middle seat for a six-and-a-half-hour overnight flight compounded the discomfort. Moving forward, I will always purchase a seat assignment to avoid this situation.
