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

Monitor control didn’t work & couldn’t figure out how to lay bed flat so I slept very poorly. Cabin was very cold

Excellent flight. On time. Great staff. Clean and crisp cabin.

The airline was fine, but I did want to share about Kayak's error through Underpricer. The original booking was purchased with ANA, and Kayak booked it with United. This is a mistake that should not be happening, since the price I paid was with ANA and that was my preference. I appreciate the efforts done to make this right by paying for the seat preference, but sitting in the back of the airplane under economy is not enough to make this error right. ANA Airlines was the experience I wanted considering this was a life time experience that my family and I wanted to have as part of our Japanese experience. Please work on your affiliation with Underpricer to make the right bookings that the customer pays for. In my situation, I could of paid less for a United ticket versus my original payment with ANA Airlines.

The Manila airport was under renovation so there was no business class lounge. The double security check was disorganized and the flight attendants were grouchy.

Know that the movies that you are going to be offered are the oldest be rated movies they could possibly get. They may have one or two new movies that they keep advertising but when you’re flying 15 hours, there is nothing to see past the first new movie.

Flight attendants on United are the worst in the business. Can’t be bothered to provide even basic levels of service and are as rude as anyone can get. This flight was not an exception to that rule.

Friendly crew, but we were delayed for more than an hour and had to change planes due to maintenance issues.

Wonderful and fast TSA checkpoint. The line was fast and our gate was close by

Airline did not explain reasons why flight was delayed two hours. Explanations were badly needed and rarely provided. Problem seemed to clearly be the airline’s fault and not the fault of the weather or airport.

I don’t like the music section but I believe it was a cost decision. I changed my flight last minute due to work issues and had to sit way in the back. The seats were way closer together than I would have preferred.

The plane was up-to-date, and the free wi-fi was very much appreciated! All of the ports functioned well, and the entertainment choices made the flight much more enjoyable. One of the flight attendants was unfriendly, but the flight was enjoyable overall.

The food was good. I almost didn't get a seat on the flight unless I agreed to sit in emergency exit.

I got bumped by Qantas to American Airlines incurring a 6 hr layover at lax. I was not happy

The flight attendant was very polite and attentive. The food was good.

I had a comfortable and enjoyable experience. The entertainment options were plentiful, the food was appetizing, the snacks were tasty, and the staff was friendly, professional, and helpful.

Smooth flight. From the early boarding and all were on board before departure time and arrived early in ONT. Great crew. Thank you!!!!

Amazing I love American. I’ll never fly anyone else if I can help it.

Everything was great except for the wifi was junk. Crew was super friendly and helpful

It was fine. I didn't love the food but it was at least a real attempt at serving a meal, unlike my earlier flight from Nashville to Dallas.
