Pros: The flight attendants in first class were very very pleasant. Service was amazing.

Cons: Boarding was extremely congested. I know ithis is out if UA control but it seems like it's getting more worst. The food aka snack that was served on the flight was a cold muffin. Not to happy with a cold muffin. I'd rather have chips or pretzels.

Pros: Nothing

Cons: Our flight was delayed and despite assurances by United staff at the gate in Seattle that we would make our flight in SFO to Zürich we were too late and we missed our flight to Zürich. 14 hours later we are still at SFO trying to get on a flight to Frankfurt then on to Venice. We shall see if it actually happens. The couple we are traveling with gave up and went back home to Boise. They also bought their tickets through Kayak.

Pros: Everything was great! This was my first time flying Alaska Air and I could not have had a better trip! Everything ran according to schedule, I was comfortable during the flight, slept the entire time, staff was great!

Cons: The woman making announcements did not specifically announce the duration of the flight as we were departing. I was able to figure it out on the map option on the screen, but I would've liked to hear it verbally. Only suggestion I would have is an announcement on the plane for which baggage claim belt our luggage would come out of. I may not have heard it though, if there was an announcement. It was not difficult at all to figure out once I was in the baggage claim area, however if this was known while we were still on the flight, I prefer to know this info!

Pros: The airplane was clean and the crew was very friendly. The landing was one of the smoothest I have ever experienced.

Cons: After paying for my carryon bag - a ridiculous $50 - and then getting nothing to eat or drink on a four hour nonstop flight unless I bought it, I ended up not really saving any money over a more expensive airline. They also tried to charge me for choosing my seats while I was checking in for the flight online. The website was unclear and not easy to navigate so I ended up having to check in with an agent at the airport which I haven’t done in years.

Cons: Kayak a howed my gate as something that didn’t exist at the terminal. I went to a kayak help desk to have a ticket printed that showed my TSA precheck because it wasn’t showing on my mobile ticket, and no one was there to help. I waisted for 10 mins. It then took me nearly 2 hours to get through security. I asked if I could get through quicker and was told I could not, despite it being passed my boarding time. I then ran to my gate where I waited for another 10 mins (no one was there, again) and then an employee came out and said they couldn’t let anyone board once the door was shut. He then directed me to the delta help desk (there was at least 20 people behind me who missed their flight). I then had to pay an additional $75 to get a later flight. The whole experience was awful and I’m disappointed with Kayak and the gate confusion, but mostly Delta and the lack of customer service.

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.
