Booking engine for booking airline tickets on multiple host environments

Abstract

A system and method of booking an itinerary on at least one of a multiplicity of host environments include a plurality of host adaptor modules. Each host adaptor module is configured to interact with one of the plurality of host ticketing environments. A booking engine is provided for receiving commands related to booking the air travel itinerary and determining an appropriate host ticketing environment for processing the commands based on a number of predefined criteria. When the booking engine receives a command it forwards the command to a first host adaptor module which is associated with first host ticketing environment selected by the booking engine for processing the command. The host adaptor module receives the command and issues the command to said first host ticketing environment. The first host adaptor module in turn receives a response from the first host ticketing environment and determines whether the response comports with an expected response. If the response does not comport with the expected response, the booking engine identifies a second appropriate host environment for processing the command and forwards the command to a second host adaptor module associated with the second host ticketing environment. The second host adaptor module then issues the command to the second host ticketing environment.
