The flight was delayed by a hour and I wish they had communicated it sooner. No issues on the plane, it did take a while for food to come.

The flight was delayed by a hour and I wish they had communicated it sooner. No issues on the plane, it did take a while for food to come.

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.

Staff could’ve been a little more cordial. The men were much more friendlier than the women. My daughter and I also missed the 2nd to last meal as we were sleeping but that is on us.

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.

Did not like that we couldn't complete check in on-line without providing pictures of our passports. Worry about identity theft. We had no delays and boarding was handled In an efficient manner.

Both my flight where delayed Had 25min to make it to my transfer flight

I just got back from a trip with 3 flights each way. The flights were good and we were happy with out experience. There was one steward on our first flight that was harsh and grump with passengers. It did not leave a good impression. All of the other flight crews were great on the other five flights.

They changed my flight 5 hours before it took off and changed my connecting airport messing up my entire 1st day in Japan.

United needs to figure out its Economy PLUS standards; its better than economy but that's not saying much. It seems like United stripped away all the basics for an international flight (such as In Seat entertainment) and repackaged some of them as plus. Would not fly United internationally again.
