PriceHash

PriceHash tracks airline fares for the specific route you care about and emails you only when it's genuinely a good time to book. It scores each fare from 0 to 100 using deterministic code based on the route's own price history and the time until prices typically rise, never relying on national averages or commissions. If data isn't solid enough, it stays silent, so you get fewer but more trustworthy alerts. You book directly with the airline or site you prefer.
