Smooth flight, nice staff, on time

Not enough leg room!!! The new planes cram us in even tighter. Unless you pay more, you suffer. Why should we have to pay more just because we are tall??!! Pocket for book etc is way too small.

The flight crew was nice and there was no problem with the actual flight. The issue was with the United employees at the check in area.

The employees at IAD were grumpy and put off by helping us passengers. The kiosk lines were full so after having waited for a while I went to the actual counter since there we no people in line and the agent chased em back to the kiosk. I felt that that was a very poor reflect of customer service. I expect more from United.

Not much.

Where do I start. Ticket counter at check in is an abomination even if you did it online as they suggest. The airline groups together those needing check in and those dropping off bags which makes no sense at all. Results in a long process. Nickel and dime you until the savings from a traditional airline is non-existent. Seats are uncomfortable, crew is unpleasant. No wifi or entertainment. And baggage is always delayed. Pay the money for a regular airline.

Being wedged in the middle seat after two overseas flights and seeing stand-by passengers in isle and window seats in rows ahead of mine... no, I did not appreciate that. In other words, UA is accomodating stand-by passengers before accomodating customers who have purchased tickets. Try sitting in a middle seat after two overseas flights... especially as a tall person with no knee space and a super-uncomfortable seat with the headcushion area reaching only your neck. Those seats were clearly made for folks under 5'8"-5'9".

Once again, your people need to cater to the people that flight. The very first time I flew with United was December 14, 1982. I was 7. As an adult I have either flown with Delta or US Air. I went with United on this trip and I have to say that I am never going back on another United flight.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
