Booking your travel arrangements online has now become cheaper. Most major online travel agencies have waived their nominal booking fees, either for a promotional length of time, or permanently. The latter is the case with online travel portal Expedia, which has permanently waived its $10 booking fee, in order to bring in more customers. Travelocity, Orbitz, and CheapTickets currently have "no booking fees" promotions running.
Due to the recession, and in turn the decreased demand for both business and leisure travel, online travel agencies have seen decreasing sales and profits. It seems as though the removal of booking fees will remain a mainstay, at least into the foreseeable future.
