No free food besides pretzels on an almost 8 hour flight. Any decent seat is an upchaege to economy plus. WiFi slow, only can access entertainment if you have app download on phone.

Nice seats, very helpful staff at ticketing and nice crew

Reservation was deleted so check in took a very long time and my seat (reserved weeks in advance) on the long international flight was reassigned to a very undesirable location.

My United connecting flight was delayed. I rushed to arrive at the gate prior to the departure time to be told the plane had left early and I had been rescheduled to the next morning at 7am. However, there were no vouchers available for me to stay in a hotel or get food. So, I was able to get a flight on American that got me home the same night. By the way, the American flight was delaying takeoff to wait for passengers who had been delayed on their connecting flights.

People who help me with my 87 year old mother we extremely thoughtful.

I did not like having to exit plane on the tarmac. It was difficult for my 87 year old mother, and the if the weather had been bad this would have been very unpleasant and extremely difficult for everyone!

I booked a LATAM flight for a 10.5 hour flight specifically because they have better in flight entertainment. I arrived at the airport and found it it was operated by AA. 10.5 hours with zero in flight entertainment. HORRIBLE EXPERIENCE.

had to take another flight, ticket agent was able to change me to a different flight on JAL. however, JAL could not access the ticket info and ticket agent would not take my payment. result was missing that flight, ticket manager told me it's my fault and tough luck no refund. American airlines told me the same, ended up losing my money for the ticket purchase. i booked another new flight with another airline direct. worst experience in my life using kayak.

The flight was over 4 hours delayed, and I didn't receive a notification that it was delayed until an hour after the flight was supposed to take off, which would have been ideal given that I had to pay 5x surge pricing for my uber to get there by the original scheduled time. Once we were about to board the plane, we were told again that it was further delayed. The crew was cranky and tired as they had clearly been dealing with delay issues the whole day. There were no tv's on the flight and we were told there would be free wifi to stream to our phones, however the wifi was so slow that it couldn't even load a single picture from the internet. Oh, there were also no decent food options on the flight. I will avoid United at all costs in the future, as my flight down was also over 3 hours delayed.

I was traveling for medical reasons and the Delta crew took great care of me, made sure I was at my connecting gate on time, and even put me in a better seat on the plane. Not sure if that was a coincidental upgrade, or intentional, but it was perfect.

We were initially told that our flight would arrive early. Then we sat on the tarmac for a half hour before anyone could be bothered to tell us we were waiting for the plane to be de-iced.

Oh the crew was very pretty. They spent more time on themselves their hair their make up and on their phones than they did the entire first class. Check our flights and miles. We fly AA ALOT for ourselves and other. WCB4350 Shipman. We don’t complain ever. But when you spend what we do and only just get your first drink with your dinner in the air is utterly ridiculous. Never got a clean up or a second drink. Had to interrupt the glam squad from their phones and make up bringing them our dirty glasses and trash asking for a second drink. Not impressed with this crew at all! Normally AA IS TOP KNOTCH. So it sets the standard that we’ve been accustomed to however complete and total letdown on this 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.
