I didn't get a chance to book

So I checked my suitcase and the terminal employee who checked me in tells me I have to hurry to flight (30 mins to board). I get there before boarding and the counter kid says he sold seat to someone else. Why didn't baggage taking employee alert me to this before? That my seat was sold? Really?

They sold my ticket - I checked in along w my luggage in the terminal and when I got to the gate, the agent said he sold my ticket to someone else. They are offering incentives/refund now but really? He apparently told management i voluntarily surrendered tickets, but now I'm to sign a document saying that never happened. I had to use united to get home. it was a nightmare.

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.
