Economy Basic check-in was easier than I'd expected it to be, security was quick and seamless. Once on board the aircraft, the flight crew kept us informed about possible weather issues (e.g. turbulence), including the approximate time to expect it, how long it might last, and that it would probably preclude in-flight beverage service. Flight attendants offered to provide one-at-a-time beverage service to those "really in need of a drink." I thought that was pretty gracious under the circumstances, and was happy to see that passengers didn't take advantage of the option :-). Looks like United is doing its best to counteract its recent negative publicity. Well done!

Seats were really neither notably comfortable nor notably uncomfortable. I think they were slightly on the comfortable side.

Would be nice to have more modern aircraft amenities, like power outlets for device charging, and display screens with at least some complimentary entertainment, or at least flight path tracking. Boarding counter lady was obnoxiously strict about not letting our carry-on bags to be carry-on. She made us test them in the size device and said they were too big, even though they could easy be pushed into the space, and regardless of the fact that we just flew on an American Airlines flight with them as carry-on and were only on a layover with them! Regarding the previous AA agent who let them be carry-on, she said "shame on them." Complete opposite of the positive experience we had with her counterpart in Phoenix. ಠ_ಠ

When we landed in Washington DC we sat on the Tarmac for an hour because there was no gate for the plane to park at. This caused me to miss my connection flight to Albany. I was put on a standby list for a flight that was leaving 7 hours later. They never offered to give me a meal voucher.

The flight was cancelled. I didn't receive a refund or free hotel accommodations. I've been on flights in Africa where free hotel accommodations were standard for a layover over 3 hours. A little embarrassing that an airline in America can't afford a hotel for people stranded in a city overnight.

however on the initial trip to cozumel we where rerouted from kc to huntvilles therefore missing our connecting flight to cozumel so the airline was accomodating and reseated us on a flight to cancun instead and I was thankful but i know that that flight was cheaper when i booked this but i didnt want to make the treak to cancun and bus and then ferry to cozumel but ended up doing that anyway is there any way at all to be compensated for the diffrence I am not upset at all but that made for a really long day getting there Just putting it out there

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,
