Flight was on time and I received my checked baggage.

Seat was uncomfortable due to insufficient foot space. All (about 6) overhead bins in the rear of the aircraft were full because crew stored “essential equipment” in them. Crew was not professional. After takeoff they never came around to see if anyone needed anything and not even a glass of water was offered for the entire flight. They didn’t even ensure that everyone wore seatbelts on landing - woman next to me was stretched out hugging her companion while landing wilth unbuckled seatbelt. Entertainment screen did not wirk properly.

Despite delay, pilot made up time in air and we made our connection in Denver. Advice to download United app for free entertainment ahead of takeoff meant we didn't miss the chance to offer movies to our kids on flight. In-flight crew was incredibly friendly/helpful.

Gate attendant was INCREDIBLY unfriendly - made no eye contact or completely ignored our verbal greetings/thanks during early boarding w/ our young child. Delayed an hour out of Baltimore, we were worried we'd miss our connection.

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.
