Sparkfare tells you whether an international flight price is good, by comparing it with that route’s own last 30 days. Checking a fare is free, with no signup. Get at most one email a day when a fare from your home airport beats its usual price, plus Away Mode, a checklist for everything around leaving. Sparkfare doesn’t sell or book travel; it sends you to the booking site. Fares are cached, so a price can change or be gone when you click.
