- “Farecast is a service that predicts airline pricing in the future (U.S. domestic market only), helping customers decide if they should purchase a flight now, or wait. Theyve been testing a product which allows users to lock in a price found on the site for up to a week. For $10, customers will be protected against any price increases for that flight. This is, effectively, the purchase of an insurance policy against the risk of future price increases.”
