Nope! Farelert is a free online tool which allows users to find, compare and track flight and hotel* prices by searching over 700 travel partners (such as airlines, online agents, travel websites) and alerts them when the price has decreased. Once you decide to book, you’re directed to the airline or relevant booking partner associated with your flight/hotel booking.
*Hotels currently do not feature price tracking. Don't worry... We're on it though!
