Thanks for this comment. If we think about a simple metasearch engine which just redirects your search to other search engines this is true, there is way less to optimize there. In reality, if you are a provider of travel bookings or a travel operator, any final calculation of price and availability is a result of a multiple conditional sub-calculations driven by actual contractual agreements between underlying parties and making it fast along with multiparameter search (where parameters may also change their values in real-time). And to make it fast is non trivial.
