Most alerts start on about a 10-minute schedule, with timing adjusted for demand and provider conditions. If a check detects a match, book fast on the official reservation site (we never book for you). By creating an alert, you agree to the Terms and Privacy Policy; turn alerts off anytime from your dashboard or the link in any alert email.
