Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

The flight was canceled the day of the flight. United says it was FAA issue, with some 35 flights canceled and more delayed.

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

I do prefer to fly United and have always had excellent service, except for bad weather. Flights are on time and staff is alway curtious and helpful

Since when do I have to pay for my checked bag? I have a United Explorer mileage plus silver card and I was charged for my checked bags. This also is an international flight. So I would like an explanation to be clear before I choose an airline please?

Plane 3 hours late. Missed connection. No help from gate staff. App horrible. Lost connection repeatedly. No service desk. Finally got help from young girl driving cart.

The flying experience was great. The flight was on time with no boarding issues during a peak travel period. The short cut baggage drop and process was not smooth and efficient at Dulles.

The negative was the wait at the airport coming back. I checked my bags in, an hour before boarding and I get the notification that my flight was delayed. Rather had gotten the notification while I was at the hotel. Then it was delayed 3 x’s. Ugh!

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

Flight crew was amazing! I don't like that the Polaris seats are side-by-side.

No issues other than paying twice for my seat selection.

Always good Thought the seatings were a bit tight for food. Made a mess with salad and oil.

Staff was friendly helpful also good timing I rate it a 10 out of 10

Very crowded; wanted us to check in 1 & only carry on full of meds & supplies; crew very reluctant to approve! I’ve lost checked in luggage in past.. It was non negotiable in my mind!

All was good with comfort and ease of boarding. There was confusion from what gate to board at. Meant moving a long distance but I allowed plenty of time for this.

every single person involved showed their joy, working in the airline industry - it created a very pleasant atmosphere for everyone

Your crew was so so so wonderful Only thing sound be great if you kept some phone chargers and converters rest 👌👌👌👌

For boarding, after family with youngsters, you should have 65 and over. Whatever rules, enforce them. It’s frustrating for those who respect them to see aggressive people rush to the gate out of turn…

AC needs to update their fleet. Too many mechanical issues, dated planes and too many delays

A snack would have been nice instead of having to buy food.
