on time, got the seat I wanted

steward was somewhat aggressive, but was responsive one on one. Focus on size of carry on baggage was anxiety producing.

Most of my flights this time had more legroom than I’ve been seeing lately. Very pleasant flight and nice not to be so cramped. The flight also left from the same terminal in Denver as my previous flight. With a 1 hour connection that was wonderful. Keep that up, United! The crew also came by regularly with offers of water. Much appreciated.

Naturally no food except pretzels.

Glad to have lots of rice options for food!

We booked with ANA but got put on a United flight on the way back. ANA was so much nicer. We were really let down flying United, having booked an ANA flight. When they swapped our flight, they didn't seat us all together either. United crew should take lessons from ANA!

The fact that the in-flight meal was as cold as the crew, and you got to pay for that coldness. Just love it! You get me right?

The Montreal-Vancouver route was by far the worst. The attitude of the crew was denigrating and arrogant.

Luggage allowance policy was not clear, so that they can try to charge passengers extra fee. Airline blames on one another when it comes to connecting flight if we purchased a one stop flight

Escape row seat in a non-escape row wasn’t too fun or comfy. Took half the flight to connect to the WiFi to watch movies to discover that the selection was limited and poor selections at that.

The flight was safe.

Hi. I was shocked that there was no food served on the 6 hour flight from Boston to LA. And the seats are way too small. I’m not large and I felt like I couldn’t breathe. There wasn’t enough help, either.

Amenity kit in Premium economy sub par. Ear buds inadequate. Need noise cancelling headphones for the entire plane. On line "best price guarantee" is hogwash and completely untrue when tested.

First flight landed late, but second flight waited for me and other passengers. Bag didn't show up until following late due to a TSA inspection. United handled it VERY professionally.

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,
