Cookies and device storage
The site uses browser storage for requested features and your measurement preference. No advertising cookies or third-party analytics scripts are installed. Effective 15 September 2026.
Wallet storage
The local-storage key milesvector:loyalty-profile:v1 holds the wallet and saved searches you choose to save. It remains until you delete it, replace it by import or clear browser site data. Use the Wallet page to export or delete your copy.
Selected flight comparisons
The session-storage key milesvector:selected-offer preserves a selected flight comparison while you navigate to its details. It contains search-result information, not passenger details, and normally ends with the browser tab session. Provider prices still expire; check the final price independently with the airline or programme.
Measurement choice
The local-storage key milesvector:pilot-measurement remembers yes or no for optional first-party usage counts. No automatic measurement request is sent unless you choose yes. Turn the option off in either planner to withdraw for future activity, or clear site data to reset the choice. These counts do not use a visitor identifier. Feedback is sent only when you press Send feedback.
Your controls
You can use the calculators without enabling measurement or saving a wallet. Blocking browser storage may prevent saved offers and wallet features from working. Programme and provider websites you choose to visit have their own storage policies.
