MANUAL – PASSENGER TRANSPORT SUPPLY<br />
Remarks concerning method<br />
variable computation<br />
Tariffs for air transport are updated daily in a ticket consolidators data base and three times per day on commercial<br />
booking systems. In addition most tariffs are “subject to availability”, meaning, even when set up well defined trip<br />
purpose specific rules (e. g. booking in 14 days in advance, weekendstay, etc.) varying tariffs, just depending on the<br />
booking situation, apply to every set of rules defined. Therefore a function deriving average costs from available tariffs<br />
has to be used in addition. This function takes also into account, which passenger fees and aircraft specific handling<br />
fees apply for a distinct airport, which are available from the ICAO.<br />
