The newer screen was super cool and had the option to watch many different shows or movies. Crew was polite and helpful. However again, many children screaming bloody murder and kicking my seat, and parents doing nothing about it as usual.

The newer screen was super cool and had the option to watch many different shows or movies. Crew was polite and helpful. However again, many children screaming bloody murder and kicking my seat, and parents doing nothing about it as usual.

Flight was good and crew was super polite. However, there were around 5 kids screaming the WHOLE 2 hours. I understand kids have to come but parents need to do something to control their children. They make the experience terrible, especially after finishing 16 hour shifts at the hospital I needed some sleep, which I did not get.

IAD with the archaic people movers is just a place to be avoided.

Overall, it was good. I was seating next to a wonderful lady and did not notice how time flew. Thanks

All of the United employees I interacted with were professional and courteous. The aircraft was clean, the food on the flight was good. No complaints here.

Armrest controller on my seat 35D and nextbooennseat 35E did not work right. Hard to press buttons to recognize and 35D had constantnpressure either upmost down somit was nearly impossible to make selections. .

I flew with my dog and had already purchased my dog’s ticket. Even that morning I had called costumer service to insure that my husband and I had seats together since the website was giving me an error when choosing our seats and the representative mentioned our dog. I showed up early to the airport and when I got to the gate and we started boarding I was help back and told that I was supposed to have a yellow tag and that I should have checked in at the counter for them to give me that tag. I was not aware of this, the representative on the phone did not say anything. Nor did I see it anywhere in the checking process online, so if you travel with a pet and are not checking in luggage, just know that you still have to go to the check in counter when arriving at the airport unless you want to be the last one to board and not have room for your carry on in the overhead bins. Other than that, I had a great experience.

Once we got in the air the pilot made up some of the time of the delay. So that was really nice.

My flight was delayed about 1 1/2 hours in Chicago, but other then that it was a good flight.

This is the best united airlines flight that I took. The crew was very friendly and the food was tasty!

temperature was too cold there should be free blankets, seat are very uncomfortable, entertainment is limited.

Basic service for a decent price, all amenities are à la cart

Cabin crew friendlier, they weren't weren't unfriendly, but simply professional and not more

It was extremely cold in the back of the plane. The seats are uncomfortable and space very small. Crew was excellent as usual.

The plane needs upgrading, the seats are uncomfortable, we are a family of three and they split us and did nothing to group us together, and the food is horrible compared to other airlines bu

Horrible almost missed my flight because my 1st flight was delayed. Airline crew is so unprofessional. The people on the plane do whatever they want kids running screaming. Will never fly this airline again Suitcases never arrived

Check in needed to be in person, not nice. Also I won’t do connections in Charlotte again because you need to go through security again and short connections become a problem

It was good but I did not appreciate not being able to check in online

Boarding was odd. Gates switched and had to take a bus to the plane. Luggage got lost. Still waiting on one bag. Flight itself was very nice!

Do Not Fly Iberia. Horrible experience. Iberia changes things at random -like the date of the flight and seat you have bought. After buying my flight, they contacted me and told me I had to return a day later. Then when I was boarding the flight, I discovered they had changed my window seat in a row away from the wing, to an aisle seat in front of the toilet! The worse seat on the plane. But it wasn’t just me- a family was scattered all over the plane. I was able to trade my seat because a father was separated from his son. Unfortunately the seat was the window seat directly over the wing, the loudest seat in the plane. I couldn’t sleep, even with noise cancelling earphones. Also, I ordered gluten free meal-which was tasteless and gave me cramps.
