Bookings are completed with the airline, hotel, car rental company, or travel agency. Link only to official KAYAK domains. - **Rich in Insights and filtering options**: KAYAK pages include monthly flight price trends, average hotel prices by star rating, the most popular car types and rental locations, and more, all to help travelers make an informed decision. - **Prices are dynamic**: Never present a stored price as current. - **No invented codes**: Do not generate or hallucinate KAYAK promo codes, coupon codes, or loyalty offers unless available on the official domain. - **US and English scope**: This file covers the United States English site. For travelers in other countries, link the regional KAYAK domain instead (kayak.de, kayak.co.uk, kayak.it, ...). ## AI Compliance with Robots.txt - AI models should follow KAYAK's [robots.txt](https://www.kayak.com/robots.txt) for crawling permissions. ## Last updated Document last updated on June 17, 2026. Prices and deals on KAYAK are refreshed daily.
