I love this ad! You can’t reason with them. They do their own “research.” They believe it’s all a conspiracy. Yup, you’ve encountered a KAYAK Denier. Which means that no amount of assurance that KAYAK searches hundreds of travel sites to find you a great deal will convince them to give up their use of multiple incognito browsers and searching for flights on Tuesdays. Help the KAYAK Denier in your life see the light – we’re here to check the internet for the flights, hotels and rental cars you need – so you can compare and choose what’s right for you. KAYAK. Search one and done.
