I booked a flight on Kayak today and apparently it was a scam. I cannot get ANY help--just machine-talk.

I booked a flight through Kayak, which routed me to Underpricer without clearly emphasizing the tradeoffs of using a third-party agency.

After booking, I found I could not select seats directly through Aer Lingus because of the third-party restriction. Instead, I was pushed to purchase seat assignments through Underpricer for about $500.

The flight itself is valid, but the experience is frustrating. You lose flexibility and basic airline functionality, then get upsold after the fact.

This reflects not just on Underpricer, but also on Kayak for directing customers into these bookings without clearer warnings about limitations.

Recommendation: book directly with the airline or a more transparent provider.

Hands-down, the worst experience I’ve ever seen the first time, I ever used kayak and my last time. I made a Car Rental reservation about 2 1/2 hours ago, for Washington Dulles airport pick up. When I got the actual reservation, it was for Sterling Virginia 30 miles away, which is absolutely ridiculous. Then trying to make the reservation to make sure that I had it, I called Avis and Avis said no your reservation is for Sterling not Dulles airport. It took me over an hour, to get the reservation changed and then the guy from kayak charged me $75 to make the change fee and I kept asking why would I have to pay when I didn’t book it at Sterling Virginia. He made me pay the $75 fee before he would actually send me an email stating that I had a Car Rental with Avis. This is bait and awitch. This is Fraud, and I plan on going to my bank and getting my $75 back cause I’m not gonna pay it. Do not book anything with kayak. They are the biggest crooks in the world. I would rather pay 50% more than book with them and any day of the week. Run run run away from them absolute crooks.

Evageline did an excellent job and was extremely pleased with her customer service. She was prompt and gave answers to all questions that I had. Will surely give her a five star rating.

You get what you pay for. They do not book, they have third party "agencies" that only want to upsell and not support customer when they need it. If you have a issue with your flight you are on your own.

I hate the commercial does not do anything to me baaaaad acting cmon you can do better by changing your marketing guy please

Kept refreshing while I was attempting to book an international flight.

Each time, it cleared the cache and forced data re-entry.

Apparently this is because their pricing is dynamic and any changes force the user to startover.

Lame business model.

I am absolutely furious. I searched on Kayak for a hotel stay from March 4th to 5th (tonight). Kayak redirected me to Agoda, but during the redirect, the dates were silently changed to March 11th–12th.
​I trusted the search results and paid for the hotel, only to realize I lost my money on a booking I never wanted. This is a deceptive practice between Kayak and Agoda. They lure you in with a price for your date and then switch it at checkout. Total scam – do not trust them!!!!!!!!!!!!!!

Darby was very helpful in finding me a flight when nearly all flights were full

SCAM Alert on Kayak! Why on earth Kayak associates themselves with AIRFARE ASSIST, a bunch of scammers?

I booked a flight to Tenerife thru Kayak, they send me a flight confirmation, with a reservation code and all, and I thought I was done. It was a return flight, and I did not care much about it, I had the 5 digit reservation code. On my last day of vacation, I tried to check in for my flight... the flight was never paid and booked. I spent the last day of my vacation chatting with the airline, and trying to figure out what happened. It was NEVER paid for, I had no flight, and was forced to purchase a NEW return flight from United.

When I came home, I immediately disputed the charge with my credit card, and the next day, I received an email from "Vincent", a rep from AirfareAssist, stating that I need to email back and state I am not disputing the charge. I sent them all the communication with the airline, explaining to them I did not get the ticket. They never came back although I sent them subsequent emails with clear proof the flight was never issued.

Stay away from Kayak's 3rd party associates.

Very good flight search engine to compare flight prices from different websites. Lot's of filters available to find the ideal flight. Extra information available like type of aircraft used in the flight you are interested in and more. Recommend it.

Kayak is full of scammers like budget air. Do not use it. Have you noticed that those companies change constantly ? That's because after a short time the word goes out and people realize that they are a scamm

Just heard an interesting account of a Kayak customer's experience with Kayak.

He purchased a flight to Madrid from them, paid and received a confirmation email. Turned up at the airport for the flight only to find they'd booked him to fly the following day.

My God, its scam after scam.

Bloody horrible company.

They jumped in on an easyjet search. I paid for the flight but it failed so they cancelled the transaction. But they refused to give me my money back

I have just spent an hour sending various complaints - its not obvious and they don't volunteer real people to sort it out. The chat bot does what chat bots do - blanket no.

Don't bother with Kayak, go to a reputable co. They offer nothing, just cause stress and steal your money

I’ve always used KAYAK before too, but my recent experience on 1.12.2026 was very frustrating. I followed a recommendation to book a car via Booking.com, only to have them cancel the reservation a few days later with no explanation. I ended up having to book directly with Enterprise at the last minute. KAYAK needs to be more selective with the third-party sites they promote; a "confirmed" booking shouldn't just disappear without reason.

I had a very frustrating experience with Kayak. The prices shown initially were misleading, and once redirected to third-party sellers, the final cost and conditions were very different from what was advertised. This caused confusion and wasted time.

I booked a rental car in October 2025 through Kayak, which made the booking through Priceline. The actual rental car company was Europcar. When I arrived at the Europcar location to pick up the car, it was out of business. A Europcar employee who happened to be there cleaning out the office told me the location had been permanently closed several weeks earlier and that she had contacted Priceline repeatedly to alert them of the need to rebook the affected bookings, with no reply. I ended up taking a taxi 45 km (at a cost of 77 British pounds) to the nearest open Europcar location, where they were very helpful and honoured my reservation. After my trip I contacted Kayak customer support. They denied all responsibility, saying that I must pursue the issue with Priceline, not with them. So I contacted Priceline customer support, who eventually agreed with me (after much debate) and promised that I would receive a refund of 77 British pounds within 5-10 business days. That was several weeks ago. I have not received any refund. From now on I will avoid third-party aggregators like Kayak and Priceline and try to make bookings directly with the actual vendors from now on!

I never received my money back thank you for screwing me yall suck

Poor customer service. We booked a car in Hawaii during Christmas break and kayak bailed out. Terrible experience, wouldn’t recommend AT ALL

This is NO1 flight search tool. It's so easy to use, and almost equally showing every provider so you have the freedom of choice.
I ALWAYS use kayak and it's ALWAYS giving lowest price across all platform.

Yes more freedom always comes with more scam. But it's not kayak's fault.
If you got scammed by justfly or edreams, it's justfly or edream's fault, it's NOT kayak's fault, NOT google's fault, NOT att's fault, NOT mcdonald's fault.
You might say "I won't be scammed if mcdonalds don't sell their burger to justfly", yes good point.
