Cookies are small text files that are stored on your device (computer, smartphone, or tablet) when you visit a website. They are widely used to make websites work efficiently and to provide information to the site's operators.
Cookies can be "session cookies" (which expire when you close your browser) or "persistent cookies" (which remain on your device for a set period or until you delete them). They can be set by the website you are visiting ("first-party cookies") or by third-party services embedded in that website ("third-party cookies").
Under UK GDPR and the Privacy and Electronic Communications Regulations (PECR), non-essential cookies require your consent before being set. This site sets no non-essential cookies of its own, so it shows no consent banner. The KAYAK search box embedded in our pages sets KAYAK's own cookies on kayak.com; they are listed below.
The table below lists all cookies currently used on CompareFlights.co.uk:
| Cookie Name | Provider | Purpose | Duration |
|---|---|---|---|
| _ga, _ga_* | Google Analytics | Not set on this site. Google Analytics runs in consent mode with analytics storage denied: it receives anonymous, cookieless page-view and click counts and stores no identifier in your browser. | Not set |
| Apache, cluster, kayak.t, kayak.mc, p1.med.sid | KAYAK (set on kayak.com) | Set by KAYAK when a page that contains the KAYAK search box loads, and when you click through to KAYAK. KAYAK uses them to run the search and to record that the visit came from CompareFlights.co.uk. They are KAYAK's cookies on KAYAK's domain; we cannot read them. | Session to 400 days |
| viator_ref | Viator (Tripadvisor) | Affiliate tracking cookie set when you click through to Viator (tours and activities). Used to attribute bookings and commissions. | 30 days |
